问题

项目报异常：

1

Unsatisfied dependency expressed through field 'articleService';
Unsatisfied dependency expressed through field 'baseMapper';

解决方法

应该是Mapper没有被扫描到

  • 方法一：添加@MapperScan("xxx.xxx.xxx")注解, xxx.xxx.xxx就是你Mapper所在的包

    @SpringBootApplication
    @MapperScan("org.bailang.mapper")
    public class BaiLangBlogApplication {
        public static void main(String[] args) {
            SpringApplication.run(BaiLangBlogApplication.class, args);
        }
    }

  • 方法二：在mapper接口上面添加@Mapper注解

    @Mapper
    public interface ArticleMapper extends BaseMapper<Article> {
