application.yml

spring:
 datasource:
  url: jdbc:mysql://127.0.0.1:3306/db01?serverTimezone=UTC&characterEncoding=utf8
  driver-class-name: com.mysql.jdbc.Driver
  username: root
  password: root

mybatis:
 table:
  auto: update
  #create系统启动后，会将所有的表删除掉，然后根据model中配置的结构重新建表，该操作会破坏原有数据。
  #update系统会自动判断哪些表是新建的．哪些字段要修改类型等，哪些字段要删除，哪些字段要新增，该操作不会破坏原有数据。#none系统不做任何处理。
  #add新增表/新增字段/新增索引新增唯一约束的功能，不做做修改和删除(只在版本1.0.9.RELEASE及以上支持)。model:
 model:
  pack: com.qs.entity #扫描用于创建表的对象的包名，多个包用"."隔开
 database:
  type: mysql #数据库类型目前只支持mysql
mybatis-plus:
 #1.如果是mybatis直接在mybatis下增加该配置。
 #2.如果使用properties配置方式,要写成mapperLocations
 mapper-locations: classpath*:mapper/*.xml,classpath*:com/gitee/sunchenbin/mybatis/actable/mapping/*/*.xml #第一个是自己写xml的路径，第二个是固定的

启动类上添加注解

@MapperScan({"com.gitee.sunchenbin.mybatis.actable.dao.*"})//固定的
@ComponentScan("com.gitee.sunchenbin.mybatis.actable.manager.*")//固定的
@SpringBootApplication
public class MybatistestApplication {

    public static void main(String[] args) {
        SpringApplication.run(MybatistestApplication.class, args);
    }

}
