Last Sunday, we went on a field trip. It was very interesting now; let me tell you something about our field trip. We got up early in the morning and we had breakfast together. Then, we rode to East park after we checked our backpacks and bikes. After one and a half hours, we arrived there. First, we went to the zoo those animals. There are monkeys, pandas, elephants, bears, wolves and so on. The animals were very cute and interesting. Then, we went boating. In the boat, we told jokes, sang songs and we also took many beautiful pictures. At last, we climbed up the mountain for our picnic. We ate many delicious food and fruits. We were very happy. What a special trip!

Spring的循环依赖的理论依据其实是基于Java的引用传递，当我们获取到对象的引用时，对象的field或则属性是可以延后设置的(但是构造器必须是在获取引用之前)。Spring的单例对象的初始化主要分为三步：（1）createBeanInstance：实例化，其实也就是调用对象的构造方法实例化对象（2）populateBean：填充属性，这一步主要是多bean的依赖属性进行填充（3）initializeBean：调用spring xml中的init 方法。从上面讲述的单例bean初始化步骤我们可以知道，循环依赖主要发生在第一、第二部。也就是构造器循环依赖和field循环依赖。那么我们要解决循环引用也应该从初始化过程着手，对于单例来说，在Spring容器整个生命周期内，有且只有一个对象，所以很容易想到这个对象应该存在Cache中，Spring为了解决单例的循环依赖问题，使用了三级缓存。

Walking close to it, you will feel the faint smell of flowers, which makes you comfortable. They are not only beautiful, but also full of life.

Spring数据校验spring拥有自己独立的数据校验框架，同时支持JSR303标注校验。springDataBinder在进行数据绑定时，可同时调用校验框架完成数据校验工作。在spring mvc中则可直接通过注解驱动的方式进行数据校验Validator校验接口boolean supports(Class<?> clazz)：该校验器能够对clazz类型的对象进行校验void validate(Object target,Errors errors)：对目标对象进行校验，并将校验错误记录到errorsLocalValidatorFactoryBeanLocalValidatorFactoryBean既实现了spring的validator接口，也实现了JSR303的Validator接口。只要在spring 容器中定义一个LocalValidatorFactoryBean，即可将其注入到需要校验的Bean中。<bean id="validator"class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>Spring mvc数据校验<mvc:annotation-driven>会默认装配好一个LocalValidatorFactoryBean，通过在处理方法的入参上标注@Valid注解即可让spring mvc执行数据校验工作。public String handle91(@Valid @ModelAttribute(“user”)Useruser,BindingResult bindingResult){if(bingingResult.hasErrors){return“/user/register”;}return “/user/showUser”}将入参对象添加@Valid注解，同时紧跟其后声明一个BindingResult的入参，根据BingingResult即可判断是否存在错误。绑定接口既可以是BindingResult也可以Errors类型在页面显示错误spring mvc除了会将表单/命令对象的校验结果保存在对应的BindingResult或Errors中，还会将所有校验结果保存到隐含模型中，也就是说即使处理方法的签名没有对应于表单/命令对象的校验结果入参，校验结果也不会丢失，它们始终可以在隐含模型中获取。隐含模型中所有数据最终通过HttpServletRequest的属性列表暴露给JSP视图对象。通过国际化资源显示错误信息每个属性在数据绑定和数据校验发生错误时，都会产生一个对应的FieldError对象，FieldError实现了org.springframework.context.MessageSourceResolvable接口。MessageSourceResolvable是可用国际化资源进行解析对象。MessageSourceResolvable提供3个接口Object getArguments()：返回一组参数对象String[] getCodes()：返回一组消息代码，每个代码对应一个资源属性，可以使用getArguments()返回的参数对资源属性进行参数替换String getDefaultMessage()：默认消息当一个属性校验失败后，校验框架会为该属性生成4个消息代码，这些代码以校验注解类名为前缀，结合类名、属性名、属性类型名生成多个消息代码如User类的password属性标注了一个@Pattern的注解，当校验失败后会产生如下4个错误代码Parttern.user.passwordParttern.passwordParttern.java.lang.StringParttern当使用Sprng mvc标签显示错误信息时，Spring mvc查看web上下文是否装配了对应国际化消息，如果没有，则显示默认的错误消息，否则使用国际化消息对错误代码进行翻译。如果在数据类型转换或数据类型格式时发生错误，或者该有的参数不存在，或者调用处理方法时发生错误，都会在隐含模型中创建错误消息，其错误代码前缀说明如下:required：必要的参数不存在，如@RequestParam(“param1”)标注了一个入参，当请求参数不存在时typeMismatch：在数据绑定时发生数据类型不匹配methodInvocation：spring mvc在调用方法时发生错误示例如果”aaa”非数字参数传递给User的salary属性，将发生数据转换的错误，Spring将为该错误生成如下错误代码typeMismatch.user.salarytypeMismatch.salarytypeMismatch.longtypMismatch装配国际化资源<bean id="messageSource"class="org.springframework.context.support.ResourceBundleMessageSource"><propertyname="basename"><value>conf/i18n/messages</value></property></bean>也可以通过basenames属性指定多个国际化资源在conf/i18n下添加基名为messages的国际化资源，一个默认的messages.properties，另一个对应messages_zh_CN.properties自定义校验规则通过@InitBinder注解的initBinder方法中装配自定义MyValidator@InitBinderpublic void initBinder(WebDataBinder binder){binder.setValidtor(newXXX());//在进行数据绑定时使用的校验器}也可以借助请求处理方法的签名传递一个Errors或BindingResult对象进来，然后在处理方法中直接校验。public String handle92(@ModelAttribute(“user”Useruser,BindingResult bindingResult)){ValidationUtils.rejectIfEmptyOrWritespace(bindingResult,”username”,”required”);//产生的错误信息对象错误代码包括//required.user.username// required.username// required.java.lang.String// requiredif(“aaa”.equalsIgnoreCase(user.getUsername())){bindingResult.rejectValue(“username”,”reserved”);//产生的错误代码如下//reserved.user.username// reserved.username// reserved.java.lang.String// reserved}if(bindingResult.hasErrors()){return “/user/register4”;}else{return “/user/showUser”;}}binder.setValidator()方法设置自定义的Validtor后，spring mvc将使用它对入参进行校验，将不在使用spring mvc框架装配的Validator对入参对象进行校验，即使入参标注了@Valid注解也不会校验

首先定义一个Gender枚举校验注解@Target({METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER})@Retention(RUNTIME)@Documented@Constraint(validatedBy = {GenderValidator.class})public @interface GenderConstraint {String message() default "Invalid gender type";Class<?>[] groups() default {};Class<? extends Payload>[] payload() default {};}下面定义一个校验器，这个比较关键, 注意校验器ConstraintValidator泛型的第二个类型一定要是Enum<Gender>类型，之前一直就是这里不对所以一直报找不到ConstraintValidatorpublic class GenderValidator implements ConstraintValidator<GenderConstraint, Enum<Gender>> {@Overridepublic void initialize(GenderConstraint constraintAnnotation) {}@Overridepublic boolean isValid(Enum<Gender> value, ConstraintValidatorContext context) {if (value instanceof Gender) {return true;}return false;}}剩下的就是在模型里面加上注解@GenderConstraint就可以了。就跟用其它validator一样，如果校验失败则通过BindingResult来处理错误结果。

每个人都有自己的理解，我肯定有不正确的地方，权且当抛砖引玉1.有的人认为使用了SSH可以大大提高系统速度，其实不然，我两个月前遇到的一个银行反洗钱项目就使用struts1.2 + jdbc开发，数据库20G左右，同样正常运行，速度还可以，我认为SSH提高的是非视图层的开发效率，减少了维护难度，对于运行速度倒不一定2.有的人认为只要会SSH的基本组合就可以了，其实不然，它们每个都是很多的版本，有些版本存在本质区别，如struts1和struts2的本质不同，spring2和spring2.5的注解配置，如果一点不考虑，一股脑采用配置文件，最终的结果只会被配置文件淹没，反而提高了维护难度，当然，太多的注解也让人昏迷，所以我认为必须对这些重点差异版本都进行学习，至少使用一会，自己去体会，找到配置文件和注解的平衡，从而提高开发效率，减少维护难度3.有的人认为hibernate好啊，有了它就万事大吉，其实不然，经过实践证明，它无法对复杂sql进行良好处理，事实上，实际项目中对复杂sql的需求相当高，远比增删改多，比如，我曾经做过的反洗钱系统中，三个大表，即使分表后依然千万级的数据量，并且三表还存在关联，使用hibernate，无法想象，所以我们使用ibatis2来专门处理复杂查询sql，以及批量修改和删除，使用hibernate来处理其他操作这里给一个SQL，看谁能使用HQL写出来，如果有，我佩服Sql代码 收藏代码 select datename(year,a.tr_date)+datename(month,a.tr_date)+(case when day(a.tr_date)<10 then "0"+datename(day,a.tr_date) else datename(day,a.tr_date) end ) as trade_date, datename(year,a.analyse_date)+datename(month,a.analyse_date)+(case when day(a.analyse_date)<10 then "0"+datename(day,a.analyse_date) else datename(day,a.analyse_date) end ) as analyse_date, datename(year,a.rep_date)+datename(month,a.rep_date)+(case when day(a.rep_date)<10 then "0"+datename(day,a.rep_date) else datename(day,a.rep_date) end ) as rep_date, a.*, d.*, s.file_name from tbriskshow a, tbriskshow_detail d, tbriskshow_relation r, rep_riskshow_file s where a.check_flag > 2 and a.sus_flag = 2 and r.id = a.id and r.tbriskdetail_id = d.id and a.status = 0 and a.type = 5 and s.riskshow_id = a.id 4.合理的配置文件布局很重要，项目开发才能正常进行，不要以为将所有struts，spring配置信息放置在一个文件中会很爽，如果你感觉到爽，那是因为你做的项目太小，所以全部按某种规范分开放置，使用总配置文件来引用这些配置5.再说说视图层，当前无外乎是JSP、CSS、JS、EL、JSTL、JSF、Jquery、Ext等技术，再高级点的就是使用JSP自定义标签技术将某些东西封装起成标签表单和表格，供统一调用，其实不管怎么样，由于每个人技术层次不同，到了后面维护必可避免的难搞，所以我结合我自己做过、参与过、看过的项目，认为视图层可以这样做：将所有控件封装（有人可能会说，这得封装多少东西啊，其实主要封装了表单、表格、树形、复选下拉、对话框，就能解决大部分问题），开发人员使用标准XML来配置界面以及其方法，再通过一个标准XML格式和服务器（SSH、存储过程）进行交互，这样，哪怕一个对界面完全没有感觉的人也能做出漂亮且风格完全统一的页面，并且维护相对容易，以下是一个示例页面配置XML： <!-- 菜单操作基础表单 --> <view id="10000011_form_base_conf"> <column>2</column> <defButtons>true</defButtons> <col type="number" field="cdbh" readonly="true" value="-1">菜单编号</col> <col type="number" field="fjbh" readonly="true" value="-1">父级编号</col> <col type="input" field="cdmc" must="true">菜单名称</col> <col type="select" field="sfzy" must="true" option="是:1|否:0">是否枝叶</col> <col type="number" field="pxh">排序号</col> <col type="input" field="ljdz" must="true">连接地址</col> </view> <!-- 添加菜单 --> <view id="10000011_form_add_conf"> <ext>10000011_form_base_conf</ext> <add_func_id>10000012</add_func_id> </view> <!-- 修改菜单 --> <view id="10000011_form_edit_conf"> <ext>10000011_form_base_conf</ext> <edit_func_id>10000013</edit_func_id> <delete_func_id>10000014</delete_func_id> </view> 数据访问XML： <func id="10000012"> <param name="cdmc" type="varchar" nullValue="" /> <param name="sfzy" type="int" nullValue="0" /> <param name="fjbh" type="int" nullValue="0" /> <param name="pxh" type="int" nullValue="0" /> <param name="ljdz" type="varchar" nullValue="" /> </func> 6.最后说说JavaWeb的未来，当然我个人认为的未来，随着Iphone，Ipad，安卓的普及，JavaWeb进军手机是必然的，就像当年PC上用PB，VB做的MIS，CRM等管理类桌面程序被大清洗一样（本人原来也是个PB程序员，后来转的Java，现在还依稀记得datewindow的风采），所以我认为JavaWeb的未来就是手持设备浏览器，服务器端其实应该没有太大变化，主要前端UI部分：多风格、多点触控式完全替代传统的表格、表单都是可能的，现在已经有不少框架出现，JQtouch、Jquery Mobile、Sencha Touch等等，当然这些我自己也还在学习中，谈不出什么，但我相信这就是未来，让我们拭目以待吧

首先别急嘛，既然语法有点混乱，那就先盯着语法题做嘛，做错的要整理在错题笔记上，同时要学会反思，总结出题的出发点，做题技巧，成绩肯定上去。加油吧！

这个bean并不是你想要的。。是spring生成的一个代理哈。。 因为这个是代理。。所以还没有创建你真正想要的目标。。也就是说你想要的目标不存在。。所以我觉得没有办法哦。。不过真正的实例是你使用它的时候创建的。。你可以在调用这个方法前先使用一下她。。比如调用一下他的方法。。

本文先叙述，如何操作PDF模板生成PDF文件，再说明在SpringMVC中如何根据PDF模板生成PDF文件。使用PDF模板生成PDF文件需要以下几个步骤：下面按步骤说明：1. 使用Microsoft Office Word画好模板此步骤就不详述了，就是一个普通的Word文件（template.docx）。给个示例截图：2. 使用Adobe Acrobat X Pro将Word文件转换为带表单字段的PDF模板文件1) 打开Adobe Acrobat X Pro2) 选择“创建PDF表单”3) 选择源：（PDF、Word、Excel或其它文件类型），下一步4) 定位Word文件路径，下一步5) Adobe Acrobat X Pro会自动猜测表单字段位置，如图6) 一般生成的表单字段都不符合我们的要求，选中删除即可。7) 点击右键选择文本框，拖动到适当的位置，设置好域名称，字号，字体等。8) 保存模板文件。（template.pdf）3. 使用itext操作PDF模板，填充数据，生成PDF文件1) 需要jar包：itext.jar、itextAsian.jar2) 核心代码：package personal.hutao.test;import java.io.ByteArrayOutputStream;import java.io.FileOutputStream;import java.io.IOException;import java.io.OutputStream;import java.util.HashMap;import java.util.Map;import org.junit.Test;import com.lowagie.text.DocumentException;import com.lowagie.text.pdf.AcroFields;import com.lowagie.text.pdf.PdfReader;import com.lowagie.text.pdf.PdfStamper;public class TestPdf { @Test public void test() throws IOException, DocumentException { String fileName = "D:/template.pdf"; // pdf模板 PdfReader reader = new PdfReader(fileName); ByteArrayOutputStream bos = new ByteArrayOutputStream(); PdfStamper ps = new PdfStamper(reader, bos); AcroFields fields = ps.getAcroFields(); fillData(fields, data()); ps.setFormFlattening(true); ps.close(); OutputStream fos = new FileOutputStream("D:/contract.pdf"); fos.write(bos.toByteArray());} public void fillData(AcroFields fields, Map<String, String> data) throws IOException, DocumentException { for (String key : data.keySet()) { String value = data.get(key); fields.setField(key, value); } } public Map<String, String> data() { Map<String, String> data = new HashMap<String, String>(); data.put("borrower", "胡桃同学"); return data; }}3) 打开contract.pdf，如图至此，就实现了根据PDF模板生成PDF文件。SpringMVC的视图中已提供了对PDF模板文件的支持：org.springframework.web.servlet.view.document.AbstractPdfStamperView。那么只需要配置好此视图就可以了。具体分为以下步骤：1) 实现抽象类 AbstractPdfStamperViewpackage personal.hutao.view;import java.io.IOException;import java.util.Map;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.view.document.AbstractPdfStamperView;import com.lowagie.text.DocumentException;import com.lowagie.text.pdf.AcroFields;import com.lowagie.text.pdf.PdfStamper;public class PdfStamperView extends AbstractPdfStamperView { public static final String DATA = "data"; public static final String FILENAME = "mergePdfFileName"; @SuppressWarnings("unchecked") @Override protected void mergePdfDocument(Map<String, Object> model, PdfStamper stamper, HttpServletRequest request, HttpServletResponse response) throws Exception { response.setHeader("Content-Disposition", "attachment;filename=" + new String(model.get(FILENAME).toString().getBytes(), "ISO8859-1")); AcroFields fields = stamper.getAcroFields(); fillData(fields, (Map<String, String>) model.get(DATA)); stamper.setFormFlattening(true); } private void fillData(AcroFields fields, Map<String, String> data) throws IOException, DocumentException { for (String key : data.keySet()) { String value = data.get(key); fields.setField(key, value); } }}2) 在SpringMVC的配置文件中配置视图<!-- 按照BeanName解析视图 --><bean class="org.springframework.web.servlet.view.BeanNameViewResolver"> <property name="order" value="1" /></bean><!-- 定义Pdf模版视图 --><bean id="contract" class="personal.hutao.view.PdfStamperView"> <property name="url" value="/WEB-INF/template/template.pdf" /></bean>3) Controller中的业务逻辑处理package personal.hutao.controller;import static personal.hutao.view.PdfStamperView.DATA;import static personal.hutao.view.PdfStamperView.FILENAME;import java.util.HashMap;import java.util.Map;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import com.coamctech.sample.commons.controller.BaseController;@RequestMapping("/contract")@Controllerpublic class TestController { @RequestMapping("/export/pdf") public String exportPersonalCreaditLoanContract(Model model) { model.addAttribute(DATA, data()); model.addAttribute(FILENAME, "XXX贷款合同"); return "contract"; } private Map<String, String> data() { Map<String, String> data = new HashMap<String, String>(); data.put("borrower", "胡桃同学"); return data; }}

有三中方法可以实现验证码的功能第一种是自定义一个filter，放在SpringSecurity过滤器之前，在用户登录的时候会先经过这个filter，然后在这个filter中实现对验证码进行验证的功能，这种方法不推荐，因为它已经脱离了SpringSecurity第二种是自定义一个filter让它继承自UsernamePasswordAuthenticationFilter，然后重写attemptAuthentication方法在这个方法中实现验证码的功能，如果验证码错误就抛出一个继承自AuthenticationException的验证吗错误的异常比如（CaptchaException），然后这个异常就会被SpringSecurity捕获到并将异常信息返回到前台，这种实现起来比较简单[java] view plain copy @Override public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException { String requestCaptcha = request.getParameter(this.getCaptchaFieldName()); String genCaptcha = (String)request.getSession().getAttribute("code"); logger.info("开始校验验证码，生成的验证码为："+genCaptcha+" ，输入的验证码为："+requestCaptcha); if( !genCaptcha.equals(requestCaptcha)){ throw new CaptchaException( this.messageSource.getMessage("AbstractUserDetailsAuthenticationProvider.badCaptcha",null,"Default",null)); } return super.attemptAuthentication(request, response); } 然后在配置文件中配置下[html] view plain copy <bean id="loginFilter" class="com.zrhis.system.security.DefaultUsernamePasswordAuthenticationFilter"> <property name="authenticationManager" ref="authenticationManager"></property> <property name="authenticationSuccessHandler"> <bean class="org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler"> <property name="defaultTargetUrl" value="/index.jsp"></property> </bean> </property> <property name="authenticationFailureHandler"> <bean class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler"> <property name="defaultFailureUrl" value="/login.jsp"></property> </bean> </property> </bean> 最后在http中加入custom-filter配置，将这个filter放在SpringSecurity的FORM_LOGIN_FILTER之前[html] view plain copy <custom-filter ref="loginFilter" before="FORM_LOGIN_FILTER"/> 最后一种是直接替换掉SpringSecurity的UsernamePasswordAuthenticationFilter，这种比较复杂，但是更为合理，也是我现在正在用的。如果用这种方法那么http 中的auto-config就必须去掉，而form-login配置也必须去掉，因为这个不需要了，里面的属性都需要我们自行注入。首先需要创建一个EntryPoint[html] view plain copy <bean id="authenticationEntryPoint" class="org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint"> <property name="loginFormUrl" value="/login.jsp" /> </bean> 然后在http中配置下[html] view plain copy <sec:http access-decision-manager-ref="accessDecisionManager" entry-point-ref="authenticationEntryPoint"> 然后我们来写CaptchaAuthenticationFilter，同样需要继承自UsernamePasswordAuthenticationFilter[java] view plain copy public class CaptchaAuthenticationFilter extends UsernamePasswordAuthenticationFilter{ public static final String SPRING_SECURITY_FORM_CAPTCHA_KEY = "j_captcha"; public static final String SESSION_GENERATED_CAPTCHA_KEY = Constant.SESSION_GENERATED_CAPTCHA_KEY; private String captchaParameter = SPRING_SECURITY_FORM_CAPTCHA_KEY; public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException { String genCode = this.obtainGeneratedCaptcha(request); String inputCode = this.obtainCaptcha(request); if(genCode == null) throw new CaptchaException(this.messages.getMessage("LoginAuthentication.captchaInvalid")); if(!genCode.equalsIgnoreCase(inputCode)){ throw new CaptchaException(this.messages.getMessage("LoginAuthentication.captchaNotEquals")); } return super.attemptAuthentication(request, response); } protected String obtainCaptcha(HttpServletRequest request){ return request.getParameter(this.captchaParameter); } protected String obtainGeneratedCaptcha (HttpServletRequest request){ return (String)request.getSession().getAttribute(SESSION_GENERATED_CAPTCHA_KEY); } } 在配置文件中配置CaptchaAuthenticationFilter[html] view plain copy <bean id="captchaAuthenticaionFilter" class="com.zrhis.system.security.CaptchaAuthenticationFilter"> <property name="authenticationManager" ref="authenticationManager" /> <property name="authenticationFailureHandler" ref="authenticationFailureHandler" /> <property name="authenticationSuccessHandler" ref="authenticationSuccessHandler" /> <property name="filterProcessesUrl" value="/login.do" /> </bean> <bean id="authenticationSuccessHandler" class="com.zrhis.system.security.SimpleLoginSuccessHandler"> <property name="defaultTargetUrl" value="/WEB-INF/app.jsp"></property> <property name="forwardToDestination" value="true"></property> </bean> <bean id="authenticationFailureHandler" class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler"> <property name="defaultFailureUrl" value="/login.jsp" /> </bean> 从配置文件中就可以看出来authenticationManager、authenticationFailureHandler、authenticationSuccessHandler、filterProcessesUrl等都需要我们自行注入了。filterProcessesUrl定义的是登录验证的地址，默认的是j_spring_security_check这里我们改成login.doauthenticationSuccessHandler中的defaultTargetUrl定义的是登录成功后跳转到的页面authenticationFailureHandler中的defaultTargetUrl定义的是登录失败后跳转到的页面我们的首页app.jsp在/WEB-INF下所以需要使用服务器跳转，所以需要将forwardToDestination设为true，因为客户端跳转是不能直接访问WEB-INF下的内容的。最后在http中将FORM_LOGIN_FILTER替换掉，最终http中完整的配置就变成了下面的内容[html] view plain copy <sec:http access-decision-manager-ref="accessDecisionManager" entry-point-ref="authenticationEntryPoint"> <sec:access-denied-handler ref="accessDeniedHandler"/> <sec:session-management invalid-session-url="/login.jsp" /> <sec:custom-filter ref="filterSecurityInterceptor" before="FILTER_SECURITY_INTERCEPTOR"/> <sec:custom-filter ref="captchaAuthenticaionFilter" position="FORM_LOGIN_FILTER"/> </sec:http> custom-filter中before是在这个filter之前，after是之后，position是替换。

form加上enctype="multipart/form-data"

"studentController" 中spring的一些注入的有问题吧。

Spring is coming. What a nice season! The weather is getting warmer and warmer. The flowers are coming out. How beautiful the world is! Look around, the sky is blue and the leaves on the trees are turning green. The sun is shining brightly and the air is so fresh, now everyone takes off his warm coat and is more active than before. We all have good feelings. I must say, be careful not to catch cold again. A good beginning is half done and it"s the first season in the year. We must make the best use of our time and catch every second to work and study. Do you think so?行么

一、在web.xml文件中进行如下配置： <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/classes/applicationContext-*.xml </param-value> </context-param>那么需要在工程下创建一个以applicationContext- 为开头的xml文件eg:applicationContext-jobconfig.xmlxml的头和结尾部分跟其他spring配置文件相似，就不赘述，正文如下： <bean id="youJobName(类别名)" class="com.******.YourJobClassLocation(类的定位)" /> <bean id="doYourJob(别名)" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <property name="targetObject"> <ref bean="youJobName(类别名)""/> </property> <property name="targetMethod"> <value>runMethodName(定时执行的方法名)</value> </property> </bean> <bean id="youJobNameTrigger(触发器别名)" class="org.springframework.scheduling.quartz.CronTriggerBean"> <property name="jobDetail"> <ref bean="doYourJob(别名)""/> </property> <property name="cronExpression"> <value>0 0/20 * * * ?(定时的时间配置)</value> </property> </bean> <bean id="doScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref local="youJobNameTrigger(触发器别名)"/> </list> </property> </bean>这样的配置几本就可以运转了，但是有一个地方可能是你需要根据你的需求来确定的，那就是触发时间。下面有一些关于时间配置的说明： <value>0 0/20 * * * ?</value>按顺序 <value> 秒 分 小时 日期 月份 星期 年 </value>字段顺序允许值允许的特殊字符秒 0-59 , - * / 分 0-59 , - * / 小时 0-23 , - * / 日期 1-31 , - * ? / L W C 月份 1-12 或者 JAN-DEC , - * / 星期 1-7 或者 SUN-SAT , - * ? / L C # 年（可选） 留空, 1970-2099 , - * / The "*" character is used to specify all values. For example, "*" in the minute field means "every minute". “*”字符被用来指定所有的值。如：”*“在分钟的字段域里表示“每分钟”。 The "?" character is allowed for the day-of-month and day-of-week fields. It is used to specify "no specific value". This is useful when you need to specify something in one of the two fileds, but not the other. See the examples below for clarification. “?”字符只在日期域和星期域中使用。它被用来指定“非明确的值”。当你需要通过在这两个域中的一个来指定一些东西的时候，它是有用的。看下面的例子你就会明白。 月份中的日期和星期中的日期这两个元素时互斥的一起应该通过设置一个问号(?)来表明不想设置那个字段The "-" character is used to specify ranges For example "10-12" in the hour field means "the hours 10, 11 and 12". “-”字符被用来指定一个范围。如：“10-12”在小时域意味着“10点、11点、12点”。 The "," character is used to specify additional values. For example "MON,WED,FRI" in the day-of-week field means "the days Monday, Wednesday, and Friday". “,”字符被用来指定另外的值。如：“MON,WED,FRI”在星期域里表示”星期一、星期三、星期五”. The "/" character is used to specify increments. For example "0/15" in the seconds field means "the seconds 0, 15, 30, and 45". And "5/15" in the seconds field means "the seconds 5, 20, 35, and 50". Specifying "*" before the "/" is equivalent to specifying 0 is the value to start with. Essentially, for each field in the expression, there is a set of numbers that can be turned on or off. For seconds and minutes, the numbers range from 0 to 59. For hours 0 to 23, for days of the month 0 to 31, and for months 1 to 12. The "/" character simply helps you turn on every "nth" value in the given set. Thus "7/6" in the month field only turns on month "7", it does NOT mean every 6th month, please note that subtlety."/"字符用来指定渐增的值。例如0/15出现在秒字段的时候意味着“在第0，15，30和45秒”（的时候被触发）。而5/15出现在秒字段的时候意味着“在第5，20，35和第50秒”（的时候被触发）。"*/"和"0/"的指定是等价的。注：当分子+分母的值大于该字段的最大值，如在秒钟字段出现45/20的时候，表示在第45秒以后的每20会触发一次，但是20秒以后又算做另外的时间段以内了，所以该字段的/20即失效，如改为45/10 则只有 第45 和55秒会执行一次。The "L" character is allowed for the day-of-month and day-of-week fields. This character is short-hand for "last", but it has different meaning in each of the two fields. For example, the value "L" in the day-of-month field means "the last day of the month" - day 31 for January, day 28 for February on non-leap years. If used in the day-of-week field by itself, it simply means "7" or "SAT". But if used in the day-of-week field after another value, it means "the last xxx day of the month" - for example "6L" means "the last friday of the month". When using the "L" option, it is important not to specify lists, or ranges of values, as you"ll get confusing results. L是‘last"的省略写法可以表示day-of-month和day-of-week域，但在两个字段中的意思不同，例如day-of-month域中表示一个月的最后一天，如果在day-of-week域表示‘7"或者‘SAT"，如果在day-of-week域中前面加上数字，它表示一个月的最后几天，例如‘6L"就表示一个月的最后一个星期五，The "W" character is allowed for the day-of-month field. This character is used to specify the weekday (Monday-Friday) nearest the given day. As an example, if you were to specify "15W" as the value for the day-of-month field, the meaning is: "the nearest weekday to the 15th of the month". So if the 15th is a Saturday, the trigger will fire on Friday the 14th. If the 15th is a Sunday, the trigger will fire on Monday the 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th. However if you specify "1W" as the value for day-of-month, and the 1st is a Saturday, the trigger will fire on Monday the 3rd, as it will not "jump" over the boundary of a month"s days. The "W" character can only be specified when the day-of-month is a single day, not a range or list of days. The "L" and "W" characters can also be combined for the day-of-month expression to yield "LW", which translates to "last weekday of the month". The "#" character is allowed for the day-of-week field. This character is used to specify "the nth" XXX day of the month. For example, the value of "6#3" in the day-of-week field means the third Friday of the month (day 6 = Friday and "#3" = the 3rd one in the month). Other examples: "2#1" = the first Monday of the month and "4#5" = the fifth Wednesday of the month. Note that if you specify "#5" and there is not 5 of the given day-of-week in the month, then no firing will occur that month. The "C" character is allowed for the day-of-month and day-of-week fields. This character is short-hand for "calendar". This means values are calculated against the associated calendar, if any. If no calendar is associated, then it is equivalent to having an all-inclusive calendar. A value of "5C" in the day-of-month field means "the first day included by the calendar on or after the 5th". A value of "1C" in the day-of-week field means "the first day included by the calendar on or after sunday". 关于cronExpression的介绍:　 字段 允许值 允许的特殊字符 秒 0-59 , - * / 分 0-59 , - * / 小时 0-23 , - * / 日期 1-31 , - * ? / L W C 月份 1-12 或者 JAN-DEC , - * / 星期 1-7 或者 SUN-SAT , - * ? / L C # 年（可选） 留空, 1970-2099 , - * / 表达式意义 "0 0 12 * * ?" 每天中午12点触发 "0 15 10 ? * *" 每天上午10:15触发 "0 15 10 * * ?" 每天上午10:15触发 "0 15 10 * * ? *" 每天上午10:15触发 "0 15 10 * * ? 2005" 2005年的每天上午10:15触发 "0 * 14 * * ?" 在每天下午2点到下午2:59期间的每1分钟触发 "0 0/5 14 * * ?" 在每天下午2点到下午2:55期间的每5分钟触发 "0 0/5 14,18 * * ?" 在每天下午2点到2:55期间和下午6点到6:55期间的每5分钟触发 "0 0-5 14 * * ?" 在每天下午2点到下午2:05期间的每1分钟触发 "0 10,44 14 ? 3 WED" 每年三月的星期三的下午2:10和2:44触发 "0 15 10 ? * MON-FRI" 周一至周五的上午10:15触发 "0 15 10 15 * ?" 每月15日上午10:15触发 "0 15 10 L * ?" 每月最后一日的上午10:15触发 "0 15 10 ? * 6L" 每月的最后一个星期五上午10:15触发 "0 15 10 ? * 6L 2002-2005" 2002年至2005年的每月的最后一个星期五上午10:15触发 "0 15 10 ? * 6#3" 每月的第三个星期五上午10:15触发 每天早上6点 0 6 * * * 每两个小时 0 */2 * * * 晚上11点到早上7点之间每两个小时，早上八点 0 23-7/2，8 * * * 每个月的4号和每个礼拜的礼拜一到礼拜三的早上11点 0 11 4 * 1-3 1月1日早上4点 0 4 1 1 *quartz的高级特性不仅如此 1 数据库存储 2 集群支持 3 数据库持久化任务，trigger 4 trigger 的停止，运行 5 任务的任意添加 6 比corntrigger 更详尽的任务安排 7 线程的内部数据交换

skywalking-5.0.0-alpha 已经修复的版本 skywalking-5.0.0-beta 在观察项目中的日志时，发现 有一个拦截全部Controller方法的日志切面WebRequestInterceptor类 该方法会拦截skywalking的某个方法。 导致每次Web请求，Controller虽然被执行一次，但是doAround会被执行两次。 如果在doAround中做了某些身份认证，Token校验之类的，则产生了不必要的重复请求。 在doAround中打印： 会发现调用了getSkyWalkingDynamicField。 这个方法由skywalking-agent的InstMethodsInter 生成的： SkyWalkingAgent通过 找到一个具体实现类 然后调用define 然后生成了InstMethodsInter 这个类intercept的方法中： interceptor.afterMethod对应 GetBeanInterceptor 的 afterMethod， 这里会调用getSkyWalkingDynamicField ，但是 这里会被WebRequestInterceptor拦截！！！ 。 getSkyWalkingDynamicField出自EnhancedInstance 在InstMethodsInter.afterMethod调用getSkyWalkingDynamicField的时候，不小心会被Spring的Aspect拦截。 导致重复调用了一次WebRequestInterceptor的doAround。 改写JoinPoint，并排除getSkyWalkingDynamicField方法 ： 果然一个月之前官方已经修复了这个BUG 修复的原理就是把Spring的org.springframework.aop.support.MethodMatchers 的matches 静态方法给增强了，那就是让Spring忽略EnhancedInstance接口的所有方法！ 这方法既粗暴，又优雅，非常值得学习。 相关链接 issue #1114 pull #1118
