问题： 在编译后的target文件夹下，发现只有mapper的class文件，而没有xml文件，将对应的xml文件放到这个文件夹下运行就不会出现下面的错误。说明出现这个错误的原因是maven编译时没有将xml文件放进去。

解决方法：在pom.xml中添加如下代码

...
        
            
                src/main/java
                
                    **/*.xml
                
                true
            
        
...
