SpringBoot整合MyBatisPlus

因为Spring没有收录MP，所以要自己添加MP坐标

        
            com.baomidou
            mybatis-plus-boot-starter
            3.4.3
        

修改dao层

public interface BookDao extends baseMapper {

}

修改配置文件

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/ssm_db
    username: root
    password: 123456
mybatis-plus:
  global-config:
    db-config:
      table-prefix: tbl_
