 搭建mybatis的简单demo中报错,  本人使用的开发工具为idea,使用maven构建的web项目,对比网上eclipse中的web项目配置并无异常.

原因: 开发工具不同导致的报错!     idea不会编译src下的java目录下的xml文件的,所以找不到xml文件

解决: 

方案一

    
        
            
                src/main/java
                
                    **/*.xml
                
            
        
    

方案二

在resources中配置相同目录结构,把xml文件放到里面也能解决该问题.
