问题：

相关报错如下：

***************************

APPLICATION FAILED TO START

***************************

Description:

A component required a bean of type 'org.com.mapper.UserMapper' that could not be found.

Action:

Consider defining a bean of type 'org.com.mapper.UserMapper' in your configuration.

解决办法：

一：

查看导入的@Mapper是否正确

二：

 1.给主类XXXApplication加注解@MapperScan("包名.mapper文件夹名")

 2. pom.xml文件的build节点下加入如下代码：

 
        
            
                src/main/java
                
                    **/*.properties
                    **/*.xml
                    **/*.yml
                
                false
            
            
                src/main/resources
                
                    **/*.properties
                    **/*.xml
                    **/*.yml
                
                false
