实例代码分析

3. Spring与Struts框架整合

Spring，负责对象对象创建

Struts， 用Action处理请求

Spring与Struts框架整合，

关键点：让struts框架action对象的创建，交给spring完成！

步骤：

引入jar文件

1）引入struts .jar相关文件

2）spring-core 相关jar文件

3）spring-web 支持jar包

spring-web-3.2.5.RELEASE.jar 【Spring源码】

struts2-spring-plugin-2.3.4.1.jar 【Struts源码】

配置:

4）配置XML

struts.xml 【struts路径与action映射配置】

bean.xml 【spring ioc容器配置】

web.xml

【核心过滤器： 引入struts功能】

【初始化spring的ioc容器】

查看api。

4） 代码以及配置

dao

package com.cx.dao;

/**
 * Created by cxspace on 16-8-9.
 */
public class UserDao {

    public void save(){
        System.out.println("DB:保存用户");
    }

}

service

package com.cx.service;

import com.cx.dao.UserDao;

/**
 * Created by cxspace on 16-8-9.
 */
public class UserService {

    private UserDao userDao;

    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }

    public void save(){
        userDao.save();
    }

}

action

package com.cx.action;

import com.cx.service.UserService;
import com.opensymphony.xwork2.ActionSupport;

/**
 * Created by cxspace on 16-8-9.
 */
public class UserAction extends ActionSupport{

    private UserService userService;

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

    public String execute(){
        userService.save();
        return SUCCESS;
    }
}
