1.创建类实现interceptor接口或者继承abstractinter~~~类
package com.mi.intercepter; import java.util.Date; import com.mi.action.LoginAction; import com.opensymphony.xwork2.ActionInvocation; import com.opensymphony.xwork2.interceptor.Interceptor; public class Intercep implements Interceptor{ private static final long serialVersionUID = 1L; private String name; @Override public void destroy() { System.out.println("destroy is run************"); } @Override public void init() { System.out.println("init is run************"); } @Override public String intercept(ActionInvocation invocation) throws Exception { LoginAction loginAction = (LoginAction) invocation.getAction(); System.out.println(getName()+"the***starttime is*** "+new Date()); long start = System.currentTimeMillis(); String result = invocation.invoke(); System.out.println("the endtime*** "+new Date()); long end = System.currentTimeMillis(); System.out.println(getName()+"the costtime is *** "+(end-start)+"毫秒"); System.out.println("result s result*** "+result); return result; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
2.在struts.xml文件中配置已经创建的拦截器,并且配置要拦截诶的action
<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <constant name="struts.i18n.encoding" value="utf-8" /> <package name="lee" extends="struts-default"> <interceptors> <interceptor name="simple" class="com.mi.intercepter.Intercep"> <param name="name">简单拦截器</param> </interceptor> </interceptors> <!-- 用户注册的Action --> <action name="regist" class="com.mi.action.RegistAction"> <!-- 类型转换失败、输入校验失败,转入input对应的视图 --> <result name="input">/content/registForm.jsp</result> <result>/content/show.jsp</result> </action> <action name="login" class="com.mi.action.LoginAction"> <result name="error">/content/error.jsp</result> <result name="success">/content/welcome.jsp</result> <interceptor-ref name="defaultStack"></interceptor-ref> <interceptor-ref name="simple"> <param name="name">改名后的拦截器</param> </interceptor-ref> </action> <action name="*"> <result>/content/{1}.jsp</result> </action> </package> </struts>
3.我的loginAction
package com.mi.action; import com.opensymphony.xwork2.ActionSupport; public class LoginAction extends ActionSupport { private static final long serialVersionUID = 1L; private String username; private String password; // username??setter??getter???? public void setUsername(String username) { this.username = username; } public String getUsername() { return username; } // password??setter??getter???? public void setPassword(String password) { this.password = password; } public String getPassword() { return password; } public String execute() throws Exception { System.out.println("??execute??????????.........."); Thread.sleep(1500); if (getUsername().equals("tangxiujuan") && getPassword().equals("tangxiujuan")) { return SUCCESS; } return ERROR; } }
4.此时控制台会打印出如下内容,请忽略乱码!!!重点在于拦截器!
