关于spring+springMVC+mybatis+maven搭建中的nested exception is org.apache.ibatis.binding.BindingException

以前没用maven的时候啥都很好，但是现在项目使用了maven，我也就把项目转换成了maven的方式。

项目中的mybatis使用的是mapper代理的方式进行开发，项目未迁移之前可以正常运行，但是迁移之后就一直报一个错误，

刚开始我以为是我在迁移的过程中不小心改了代码，但是经过一遍遍的代码走读，按照mapper代理的风格要求查了好几遍却没有发现任何错误，后来打开taget目录看了一下
发现了问题，

我的UserMapper.xml文件竟然没有，这就是问题所在。maven的java代码文件夹中默认不编译.xml文件，也就是说你的项目发布之后

java文件夹中的.xml文件根本就不发布，解决方案如下

在你的pom.xml文件的标签中添加如下代码

    oassm
    
        
            src/main/java
            
                **/*.properties
                **/*.xml
                **/*.tld
            
            true
        
    
    

这样你的项目发布之后.xml文件就能一起发布了，也就解决了上面的问题
