错误如图  
![在这里插入图片描述][d04cf2b06deb497297cac086b62ae068.png_pic_center]

**第一步** 查看配置文件是否正确

![查看这几个地方][cacb54c829aa4d7ea9a1bd557bb28dc3.png_pic_center]  
**第二步** 查看标签是否正确  
检查UserMapper上是否加上@Mapper  
![这里加上][04f2e65df26b46ecbfd2839a8aed31f1.png_pic_center]

**补充**第二步还是不行的话查看下POM文件是否导入mybatis-plus-boot-starter

配置mybatis-plus.mapper-locations无提示信息；  
此时发现右上角出现感叹号，Cannot resolve configuration property ‘mybatis-plus.mapper-locations’，强行敲完，启动报错。  
如图所示

检查pom文件，发现未引入包:mybatis-plus-boot-starter

<dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-boot-starter</artifactId>
        <version>3.3.2</version>
    </dependency>

欢迎补充
