1.Spring-Data-Jpa

　　JPA定義了對象持久化的標準。

　　目前實現了有Hibernate，TopLink

2.pom添加依賴

1         <dependency>
2             <groupId>org.springframework.boot</groupId>
3             <artifactId>spring-boot-starter-data-jpa</artifactId>
4         </dependency>
5 
6         <dependency
 
>
7             <groupId>mysql</groupId>
8             <artifactId>mysql-connector-java</artifactId>
9         </dependency>

3.對jps進行配置

 1 spring:
 2   profiles:
 3     active: dev
 4   datasource:
 5     driver-class-name: com.mysql.jdbc.Driver
 6     url: jdbc:mysql://127.0.0.1:3306/people
 
 7     data-username:root
 8     username: 12345678
 9   jpa:
10     hibernate:
11       ddl-auto: update
12     show-sql: true

4.新建一個people的數據庫

　　CREATE DATABASE IF NOT EXISTS yiibaidb DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

5.

springBoot的數據庫操作
