报错原因：

项目未扫描到 dao 包

解决办法：

在主启动类上加上：@ComponentScan(basePackages = {“com.XX.dao”}) 你的项目的dao层包路径，如下：

  1. @ComponentScan(basePackages = {"com.xx.dao"})//引入dao根路径
  2. //@MapperScan("com.macro.mall.tiny.mbg.mapper")
  3. @SpringBootApplication
  4. public class MallApplication {
  5.     public static void main(String[] args) {
  6.         SpringApplication.run(MallApplication.class, args);
  7.     }
  8. }
