最近业余时间在学习jpa和Springdata，趁有时间整理一下sssp搭建整合

所需各个框架jar包

</beans>

db.properties，只是基本连接

jdbc.user=root
jdbc.password=root
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql:///sssp

然后在测试类里测试一下数据库连接

package com.sssp_demo.test;

import javax.sql.DataSource;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * 测试类
 */
public class SSSPTest {
	
	private ApplicationContext ctx = null;
	{
		ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
	}
	
	/**
	 * 测试DataSource连接
	 */
	@Test
	public void testDataSource() throws Exception {
		DataSource dataSource = ctx.getBean(DataSource.class);
		System.out.println(dataSource.getConnection());
	}
}

然后在页面测试一下

User.java

package com.sssp_demo.entity;

import java.util.Date;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import org.springframework.format.annotation.DateTimeFormat;

@Table(name="SSSP_USER")
@Entity
public class User {
	
	private Integer userId;
	private String userName;
	@DateTimeFormat(pattern="yyyy-MM-dd")
	private Date userBirth;
	
	@GeneratedValue
	@Id
	public Integer getUserId() {
		return userId;
	}
	public void setUserId(Integer userId) {
		this.userId = userId;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	
	@Temporal(TemporalType.DATE)
	public Date getUserBirth() {
		return userBirth;
	}
	public void setUserBirth(Date userBirth) {
		this.userBirth = userBirth;
	}
	@Override
	public String toString() {
		return "User [userId=" + userId + ", userName=" + userName + ", userBirth=" + userBirth + "]";
	}
	
}

UserRepository.java

实现了Repository的子接口JpaRepository接口各个接口有不同的方法

package com.sssp_demo.repository;

import org.springframework.data.jpa.repository.JpaRepository;
import com.sssp_demo.entity.User;

public interface UserRepository extends JpaRepository<User, Integer>{
	
	
}

UserService.java

package com.sssp_demo.service;

import com.sssp_demo.entity.User;

public interface UserService {
	
	public User saveUser(User user);
}

UserServiceImpl.java

package com.sssp_demo.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.sssp_demo.entity.User;
import com.sssp_demo.repository.UserRepository;
import com.sssp_demo.service.UserService;

@Service
public class UserServiceImpl implements UserService{
	
	@Autowired
	private UserRepository repository;
	
	// save是Repository的子接口CrudRepository提供的方法，返回新增的类
	@Transactional
	public User saveUser(User user) {
		return repository.save(user);
	}
	
}

UserController.java 这个就直接页面了

package com.sssp_demo.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.sssp_demo.entity.User;
import com.sssp_demo.service.UserService;

@Controller
public class UserController {
	
	@Autowired
	private UserService userService;
	
	@ResponseBody
	@RequestMapping("/save")
	public String saveUser(User user) {
		User userTmp = userService.saveUser(user);
		return "hello" + userTmp;
	}
}

然后启动服务器，刷新服务器，数据库表JPA已建好

只是测试就直接在浏览器地址栏操作

http://localhost:8080/sssp_demo/save?userName=jack&userBirth=2018-07-19

数据库

ok!!  搭建成功
