    71221208243

    想使用hibernate来获取数据库里的数据,但是浏览器访问的时候 就报错了.
    eclipse没有提示语法错误,但是控制台报错了.
    MvcController.java

    package qiye.web;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

import qiye.entity.Service;

@Controller
public class MvcController {
    private static SessionFactory sessionFactory;
    static{
        Configuration configuraction = new Configuration().configure();
        sessionFactory = configuraction.buildSessionFactory();
    }
    public static Session getSession(){
        return sessionFactory.openSession();
    }
    
    
    @RequestMapping("/index")
    public String index(){
        
        Session session = MvcController.getSession();
        Service service = (Service)session.get(Service.class, new Integer(1));
        System.out.println(service.getTitle());
        
        return "index";
    }
    
}

        你这用法不正规啊，网上搜一下spring整合hibernate。

          这个用法有错误，hibernate 是对dao层进行操作，service是操作业务逻辑代码，controller是空气器，这是要明确分工，下面是个简单的小demo

          //新建UserDao
package com.purchase.dao;
import com.purchase.domain.User;

public interface UserDao {
    public void addUser(User user);
}



//新建实现类UserDaoImpl
public class UserDaoImpl implements UserDao{

    private SessionFactory sessionFactory;  
    public void setSessionFactory(SessionFactory sessionFactory) {  
        this.sessionFactory = sessionFactory;  
    }  
  
    @Override   
    public void addUser(User user) {//添加用户  
        sessionFactory.getCurrentSession().save(user);  
    }  
}

//新建service类
public interface UserService {  
    public void addUser(User user);  
    }
    
//新建service实现类
public class UserServiceImpl implements UserService {
    public UserDao userDao;
    
    @Override  
    public void addUser(User user) {  
        userDao = new UserDaoImpl();
        userDao.addUser(user);  
    }  
    }

    
//新建controller控制类
@Controller  
@RequestMapping("/user")  
public class UserController {  
    @Resource(name="userService")// 获取spring配置文件中bean的id为userService的，并注入   
    private UserService userService;     
    
    @RequestMapping("/addUser")// 请求url地址映射，类似Struts的action-mapping   
    public String addUser(User user){    
        userService.addUser(user);  
        return "redirect:/user/success";  
    } 
    }
