SSH整合之spring整合struts2(续上)

一、项目结构

二、新建UserAction，继承自ActionSupport，并实现ModelDriven<User>接口；getModel方法是用来装配对象属性的；注意，userService字段名要和applicationContext.xml中配置的userservice bean中id名称一致

package com.hjp.action;

import com.hjp.domain.User;
import com.hjp.service.UserService;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

/**

 */
public class UserAction extends ActionSupport implements ModelDriven<User> {

    User user = new User();

    @Override
    public User getModel() {
        return user;
    }

    private UserService userService;

    public void setUserService(UserService userService) {
        this.userService = userService;
    }

    public String register(){
        userService.register(user);
        return SUCCESS;
    }
}

UserAction

三、新建index.jsp文件，代码如下

<%--
  Created by IntelliJ IDEA.
  User: JiaPeng
  Date: 2015/12/13
  Time: 11:36
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title></title>
</head>
<body>
<form method="post" action="${pageContext.request.contextPath}/userAction_register">
    用户名：<input type="text" name="username"/><br/>
    密码：<input type="password" name="password"/><br/>
    年龄：<input type="text" name="age"/><br/>
    <input type="submit" value="注册"/>
</form>
</body>
</html>

index.jsp

四、新建struts.xml文件,及message.jsp文件

<?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>
    <!--常量-->
    <constant name="struts.devMode" value="true"></constant>
    <!--包-->
    <package name="hello" namespace="/" extends="struts-default">
        <action name="userAction_*" class="com.hjp.action.UserAction" method="{1}">
            <result name="success">/message.jsp</result>
        </action>
    </package>

</struts>

struts.xml

<%--
  Created by IntelliJ IDEA.
  User: JiaPeng

  Time: 16:23

--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title></title>
</head>
<body>
成功！
</body>
</html>

message.jsp

五、配置web.xml文件，主要是配置spring和struts

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
    <!--spring-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!--struts-->
    <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>/*</url-pattern>
    </filter-mapping>
</web-app>

web.xml
