spring boot 整合mybatis 配置

1.需要在application.yml中配置以下代码

mybatis:
//配置接口映射的路径
  mapper-locations: classpath:mybatis/mapper/*.xml

2.在启动类application中类上加一个注解@MapperScan("com.itxinghua.baidu.mapper")

package com.itxinghua.baidu;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
//扫描包下的所有mapper接口并交给spring管理
@MapperScan("com.itxinghua.baidu.mapper")
public class BaiduApplication {

    public static void main(String[] args) {

        SpringApplication.run(BaiduApplication.class, args

        );
    }

}
