在IDEA中利用SpringBoot整合JPA SpringBoot整合JPA的简单示例工具介绍一、创建新项目二、设置数据源三、实体类三、持久层接口四、控制层五、页面效果工具介绍 IDEA Navicat 一、创建新项目利用IDEA自带的spring初始化向导来新建一个spring的项目：设置项目名称以及包名：选择SpringBoot的版本以及添加以下依赖：然后一直next即可创建完成。项目的pom.xml文件中的依赖是这样的... 阅读详情

1.pom文件

    <parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.1.1.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>

	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-data-jpa</artifactId>
		</dependency>

		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
		</dependency>

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>


		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>
	</dependencies>

2.配置文件

spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF8&serverTimezone=GMT
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driverClassName=com.mysql.jdbc.Driver

spring.jpa.show-sql=true

server.port=8082

3.model层

package com.knife.testjpa.model;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

@Entity
public class Account {

	@Id
	@GeneratedValue
	private Long id;

	@Column
	private String name;

	public Long getId() {
		return id;
	}

	public void setId(Long id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

}

4.dao层

package com.knife.testjpa.dao;

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

import com.knife.testjpa.model.Account;

public interface AccountDao extends JpaRepository<Account, Long>{

}

5.controller层

package com.knife.testjpa;

import javax.annotation.Resource;

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

import com.knife.testjpa.dao.AccountDao;

@RestController
@RequestMapping("/test")
public class TestController {

	@Resource
	AccountDao dao;

	@RequestMapping(method = RequestMethod.GET)
	public Object test() {
		return dao.findAll();
	}

}

6.启动类

package com.knife.testjpa;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class App {
	public static void main(String[] args) {
		SpringApplication.run(App.class);
	}
}

7.测试
