spring boot 入口文件:

package com.mall.demo;

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

@SpringBootApplication
@MapperScan(basePackages = "com.mall.demo.mapper")
public class MallProjectApplication {

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

使用的編輯器是IDEA ,service實現(xiàn)類中使用Autowired注入，但運行 依然提示沒有注入成功。
錯誤信息如下：

Description:

Field categoryMapper in com.mall.demo.service.impl.CategoryServiceImpl required a bean of type 'com.mall.demo.mapper.CategoryMapper' that could not be found.


Action:

Consider defining a bean of type 'com.mall.demo.mapper.CategoryMapper' in your configuration.
