需要在根基包同级写启动类

package com.baizhi.fo;

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

@SpringBootApplication
//添加扫描文件（dao/过滤器（拦截器等））
@MapperScan("com.baizhi.fo.dao")
（过滤器）
public class Application {
    public static void main(String[] args) {    SpringApplication.run(Application.class,args);
    }
}

mapper相关内容同另一博文（ssm项目）
简单controller写法

@Controller
public class AlbumController {

    @Autowired
    private AlbumService albumService;
    //条件分页
    @RequestMapping("/showpageAlbums")
    @ResponseBody
    public Map selectPagesByConditions(Integer page,Integer limit,String albumname){
        return albumService.selectPageAlbums(page,limit,albumname);
    }
