### 解决办法 ###

正确的写法应该是:

import org.mybatis.spring.annotation.MapperScan;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    import org.springframework.context.annotation.ComponentScan;
    
    @SpringBootApplication
    @ComponentScan(basePackages = {
        "com.microblog.mapper"})
    public class BackendBlogApplication {
        
    
        public static void main(String[] args) {
        
            SpringApplication.run(BackendBlogApplication.class, args);
        }
    }
