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！

Spring与Hibernate整合：

【SSH整合:

Spring与Struts

关键点： action交给spring创建!

Spring与Hibernate

关键点： sessionFactory对象交给spring创建！

】

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】

package loaderman.action;

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

public class UserAction extends ActionSupport {

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

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

package loaderman.dao;

public class UserDao {

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

package loaderman.service;

import loaderman.dao.UserDao;

public class UserService {

    //IOC容器注入
    private UserDao userDao;
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }

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