所用到的jar(pom.xml):

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:
以上是关于maven+spring-data-jpa环境搭建的主要内容，如果未能解决你的问题，请参考以下文章
JPA---Spring-data-JPA---Hibernate
Maven 使用 spring-data-jpa 和 querydsl 构建问题
