Springboot根据实体类生成数据库表

1. 添加pom.xml依赖

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

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

2.yml配置：

server:
  port: 8080

spring:
  application:
    name: jih-manage
  datasource:
    name: test
    url: jdbc:mysql://111.231.231.56/jih
    username: root
    password: root
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.jdbc.Driver
  jpa:
    hibernate:
      ddl-auto: update
    show-sql: true

3.实体类加注解：

@Entity           实体类的注解
@Id               映射到表格中id的属性
@Gernertervalue   添加其自增的属性；

4.启动项目
