struts2多动作控制器(小实例)-原创手记-慕课网

一、创建JavaBean:LoginBean

package com.zpj.domain;public class LoginBean {        private String username;        private String pwd;        public String getPwd() {                return pwd;        }        public void setPwd(String pwd) {                this.pwd = pwd;        }        public String getUsername() {                return username;        }        public void setUsername(String username) {                this.username = username;        }}

二、创建Action：LoginAction

package com.zpj.action;import com.opensymphony.xwork2.ActionSupport;import com.zpj.domain.LoginBean;public class LoginAction extends ActionSupport {        private LoginBean loginBean;        public LoginBean getLoginBean() {                return loginBean;        }        public void setLoginBean(LoginBean loginBean) {                this.loginBean = loginBean;        }        /*        * 默认的validate()方法；        */        public void validate() {                System.out.println("这个是validate方法=====1");                super.validate();        }        /*        * 执行完这个方法后将执行默认的validate()方法；        */        public void validateSaveUser() {                System.out.println("这个是validateSaveUser方法=====2");                super.validate();        }        /*             * 默认的execute()方法；        */        public String execute() throws Exception {                System.out.println("这个是execute方法=====3");                return "ok";        }        /*        * 如果执行了此方法，则不再执行默认的execute()方法；        */        public String saveUser() throws Exception {                System.out.println("这个是saveUser方法=====4");                return "saveUserOk";        }        /*        * 如果执行了此方法，则不再执行默认的execute()方法；        */        public String checkUser() throws Exception {                System.out.println("这个是checkUser方法=====5");                return "checkUserOk";        }}

三、配置struts.xml文件

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"        "http://struts.apache.org/dtds/struts-2.0.dtd">        <struts>        <package name="s2" extends="struts-default">            <!-- 定义多动作控制器方法一 -->             <action name="loginAction" class="com.zpj.action.LoginAction">                <result name="ok">/success.jsp</result>                <result name="saveUserOk">/success.jsp</result>                <result name="checkUserOk">/success.jsp</result>                <!-- 重定向到index.jsp页面 -->                <result name="input" type="redirect">/index.jsp</result>             </action>             <!-- 定义多动作控制器方法二 -->             <action name="*loginDo" method="{1}" class="com.zpj.action.LoginAction">                <result name="ok">/success.jsp</result>                <result name="saveUserOk">/success.jsp</result>                <result name="checkUserOk">/success.jsp</result>                <!-- 重定向到index.jsp页面 -->                <result name="input" type="redirect">/index.jsp</result>             </action>        </package>        </struts>

四、创建首页index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%@ taglib prefix="s2" uri="/struts-tags" %><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head>    <title>My JSP 'index.jsp' starting page</title>    <!--    <link rel="stylesheet" type="text/css" href="http://pannijingling.blog.163.com/blog/styles.css">    --></head><body>        <center>        <!-- 使用第一种多动作控制器的调用方法-->        <s2:form action="loginAction!saveUser">             <s2:textfield name="loginBean.username" label="姓名"></s2:textfield>             <s2:password name="loginBean.pwd" label="密码"></s2:password>             <s2:submit label="登陆"></s2:submit>        </s2:form>        <hr>        <!-- 使用第二种多动作控制器的调用方法-->        <s2:form action="checkUserloginDo">             <s2:textfield name="loginBean.username" label="姓名"></s2:textfield>             <s2:password name="loginBean.pwd" label="密码"></s2:password>             <s2:submit label="登陆"></s2:submit>        </s2:form>        <hr>        <!-- 下面这个form中 action="loginDo"和 action="loginAction"效果是一样的-->        <s2:form action="loginDo">             <s2:textfield name="loginBean.username" label="姓名"></s2:textfield>             <s2:password name="loginBean.pwd" label="密码"></s2:password>             <s2:submit label="登陆"></s2:submit>        </s2:form>        </center></body></html>

五、创建登陆成功的页面success.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%@ taglib prefix="s2" uri="/struts-tags" %><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head>    <title>My JSP 'success.jsp' starting page</title>    <!--    <link rel="stylesheet" type="text/css" href="http://pannijingling.blog.163.com/blog/styles.css">    --></head><body>        <center>        <font color="red" size="20">欢迎您，登陆成功！</font>        <br><br><br><br><br><br>        <s2:a href="http://pannijingling.blog.163.com/blog/index.jsp">返回上一页</s2:a>        </center></body></html>
