一、问题

使用了Mybatis generator自动生成的bean和mapper
写完service层和controller层后运行报错A component required a bean of type 'XXService' that could not found

二、解决方式

在springBoot主入口函数Application里添加注释@MapperScan("com.SF.data.dao")
括号里为自己的mapper路径

@SpringBootApplication
@MapperScan("com.SF.data.dao")
public class Shoppingweb01Application {
    public static void main(String[] args) {
        SpringApplication.run(Shoppingweb01Application.class, args);
    }

}
