JavaWeb_(Spring框架)在Struts+Hibernate框架中引入Spring框架

　　spring的功能：简单来说就是帮我们new对象，什么时候new对象好，什么时候销毁对象。

　　在MySQL中添加spring数据库，添加user表，并添加一条用户数据

　　使用struts + hibernate框架实现用户登陆功能：当用户在login.jsp中账号密码输入错误，重定向login.jsp，并提示用户输入账号、密码错误，如果用户在login.jsp中账号密码输入正确，跳转到index.html

web.xml

　　修改UserService.java和UserDao，不用再UserAction中使用UserService userService = new UserService()，使用Spring框架帮我们new对象

package com.Gary.web;

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

public class UserAction extends ActionSupport implements ModelDriven<User>{

    public User user = new User();

    private UserService userService;
    
    public String login() throws Exception {
        
        boolean success = userService.findUser(user);
        if(success)
        {
            return "toIndex";
        }else {
            ActionContext.getContext().put("error", "用户名或者密码错误！！");
            return "login";
        }
        
    }

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

    public UserService getUserService() {
        return userService;
    }

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

    
    
    
    
}

UserAction.java

package com.Gary.service;

import org.hibernate.Transaction;

import com.Gary.dao.UserDao;
import com.Gary.domain.User;
import com.Gary.utils.HibernateUtils;

public class UserService {

    private UserDao userDao;
    
    public boolean findUser(User user) {
        
        
        Transaction beginTransaction = HibernateUtils.getCurrentSession().beginTransaction();
        User temp = null;
        try {
            
            temp = userDao.findUser(user);
        }catch(Exception e){
            beginTransaction.rollback();
        }
        
        beginTransaction.commit();
        
        return temp==null?false:true;    
    }

    public UserDao getUserDao() {
        return userDao;
    }

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

UserService.java

　　applicationContext.xml中进行Action、Service的配置，Dao暂时不配置

    <!-- 配置Action -->
    <bean name = "userAction" class="com.Gary.web.UserAction" scope="prototype">
        <property name="userService" ref="userService"></property>

applicationContext.xml

　　在struts.xml中告诉struts不用创建Action，sping来帮你创建Action
