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
