下面是程序测试代码(接口使用RESTful风格)：

1.model实体 User.java

package com.ajie.wechat.model;

import java.io.Serializable;

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.GenerationType;

import javax.persistence.Id;

import javax.persistence.Table;

@Entity

@Table(name = "user")

public class User implements Serializable {

    private static final long serialVersionUID = 7419229779731522702L;

    @Id

    @GeneratedValue(strategy = GenerationType.IDENTITY)

    @Column(name = "userId")

    private Long id;

    @Column(length = 50)

    private String account;

    public Long getId() {

        return id;

    }

    public void setId(Long id) {

        this.id = id;

    }

    public String getAccount() {

        return account;

    }

    public void setAccount(String account) {

        this.account = account;

    }

    public static long getSerialversionuid() {

        return serialVersionUID;

    }

}

2.Dao

package com.ajie.wechat.dao;

import org.springframework.data.jpa.repository.JpaRepository;

import com.ajie.wechat.model.User;

public interface UserDao extends JpaRepository<User, Long> {

}

3.Service

package com.ajie.wechat.service;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import org.springframework.transaction.annotation.Transactional;

import com.ajie.wechat.dao.UserDao;

import com.ajie.wechat.model.User;

@Service

@Transactional

public class UserService {

    @Autowired

    private UserDao userDao;

    public String add(User user){

        userDao.save(user);

        return "添加成功！";

    }

    public String addUser(String account){

        User user = new User();

        user.setAccount(account);

        userDao.save(user);

        return "添加成功！";

    }

    public User getOneUser(Long id){

        return userDao.findOne(id);

    }

}

4.controller层使用@RestController(等同于@Controller + @ResponseBody)

package com.ajie.wechat.controller;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.http.MediaType;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestBody;

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

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RestController;

import com.ajie.wechat.model.User;

import com.ajie.wechat.service.UserService;

@RestController

@RequestMapping(value = "/frame")

public class UserController {

    @Autowired

    private UserService userService;

    @RequestMapping(value = "/saveUser",

            method = RequestMethod.POST,

            produces = MediaType.APPLICATION_JSON_VALUE + ";charset=UTF-8")

    public String saveUser(@RequestBody User user){

        return userService.add(user);

    }

    @RequestMapping(value = "/saveUser/{account}",

            method = RequestMethod.GET,

            produces = MediaType.APPLICATION_JSON_VALUE + ";charset=UTF-8")

    public String add(@PathVariable String account){

        return userService.addUser(account);

    }

    @RequestMapping(value = "/user/{id}",

            method = RequestMethod.GET,

            produces = MediaType.APPLICATION_JSON_VALUE + ";charset=UTF-8")

    public User add(@PathVariable Long id){

        return userService.getOneUser(id);

    }

}

一些需要注意的地方:

spring的配置:
