Spring和Struts2集成_集成struts 2和spring得到的模式是-优快云博客

本文介绍如何将Struts2与Spring框架进行集成，通过配置让Struts2中的Action由Spring来管理，实现依赖注入等功能。包括配置struts.xml、applicationContext.xml文件，创建业务逻辑接口和服务实现，以及Action类的具体实现。

1.Struts2与Spring的集成相当于将Action的实例化交给Spring来管理

在src目录下新建struts.xml文件，例子如下

<?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">

    <package name="google" extends="struts-default">
        <action name="login" class="loginAction">
        <result name="success">/WEB-INF/page/success.jsp</result>
        <result name="error">/WEB-INF/page/error.jsp</result>
        </action>
    </package>

</struts>

2.在WEB-INF下新建applicationContext.xml，代码如下

<?xml version="1.0" encoding="UTF-8"?>

3.新建业务逻辑类和接口

package com.struts2.service;

public interface LoginService {
boolean isLogin(String userName,String password);
}
实现类

package com.struts2.service.impl;

import com.struts2.service.LoginService;

public class LoginServiceImpl implements LoginService {

public boolean isLogin(String userName, String password) {
        if("admin".equals(userName) && "123456".equals(password))
            return true;
        else
            return false;
}

}

4.新建Action类

package com.struts2.action;

import com.struts2.service.LoginService;

public class LoginAction {
private LoginService loginService;
private String userName;
private String passWord;

public String getPassWord() {
return passWord;
}

public void setPassWord(String passWord) {
this.passWord = passWord;
}

public String getUserName() {
return userName;
}

public void setUserName(String userName) {
  this.userName = userName;
}

public String execute()throws Exception{
  if(loginService.isLogin(userName, passWord)){
   return "success";
  }else
  return "error";
}

public LoginService getLoginService() {
return loginService;
}

public void setLoginService(LoginService loginService) {
this.loginService = loginService;
}
}

5.最后web.xml的配置

<?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">

<filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
Struts通过Filter启动，Spring通过Listener启动

6.客户端脚本

<%@ page language="java" pageEncoding="UTF-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>

    <title>My JSP 'index.jsp' starting page</title>

</head>

<body>
<form action="login" method="post">
