springmvc整合hibernate

摘要: springmvc整合hibernate

创建web项目

导入jar包

创建数据库

在web.xml中spring的监听器ContextLoaderListener,mvc框架的前端控制器DispatcherServlet

5、在类路径下提供spring的配置文件applicationContext.xml,mvc框架的配置文件springmvc.xml

6、创建控制器类，业务类，持久层类，并在类上使用相应的注解

package cn.internet.controller;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import cn.internet.domain.User;
import cn.internet.service.UserService;

@Controller
@RequestMapping(value="/user")
public class UserController{

@Resource
private UserService userService;

@RequestMapping(value="save.action")
public String save(User user){
userService.save(user);
return "success";
}
}

package cn.internet.dao;

import javax.annotation.Resource;

import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Repository;

import cn.internet.domain.User;

@Repository
public class UserDao {

@Resource
private HibernateTemplate hibernateTemplate;

public void save(User user) {
hibernateTemplate.save(user);
}
}

package cn.internet.service;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import cn.internet.dao.UserDao;
import cn.internet.domain.User;

@Service
@Transactional
public class UserService {

@Resource
private UserDao userDao;

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