配置web.xml设置拦截器

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<display-name></display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
</web-app>

配置struts.xml进行映射

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="helloworld" extends="struts-default" namespace="/login">
<action name = "hello">
<result name="success">/hello.jsp</result>
</action>
<action name = "welcome" class="com.qiaozhq.outman.WelcomeAction">
<result name="success">/welcome.jsp</result>
<result name="fail">/error.jsp</result>
</action>
</package>
</struts>

WelcomeAction.java

package com.qiaozhq.outman;

public class WelcomeAction {
private String name;
private String password;
public String execute(){
System.out.println("WelcomeAction execute...");
System.out.println("name="+name+",password="+password);
if("".equals(name)){
return "fail";
}
return "success";
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}

}

hello.jsp 表单提交页面

<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
