运行插件

我是点击idea maven按钮的

添加配置 application.yml

server:
  port: 8080
spring:
  datasource:
    url: jdbc:mysql://192.168.1.12/jpa?characterEncoding=utf-8
    username: root
    password: pass
  jpa:
    hibernate:
      ddl-auto: update
    show-sql: true
    #不加这句则默认为myisam引擎
    database-platform: org.hibernate.dialect.MySQL5InnoDBDialect

实战查询

单元测试,好习惯
