SpringBoot整合MyBatisPlus

1.导入mybatisplus与Druid对应的starter

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.2.6</version>
</dependency>

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
    <version>3.4.2</version>
</dependency>

2.配置数据源与MyBatisPlus对应的基础配置

spring:
  datasource:
    druid:
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://localhost:3306/mybaits?serverTimezone=UTC
      username: root
      password: root

mybatis-plus:
  global-config:
    db-config:
      table-prefix: tbl_
      #id生成策略使用数据库策略
      id-type: auto

3配置数据层的接口继承BaseMapper并指定泛型

@Mapper
public interface BookDao extends BaseMapper<Book> {

}
