sring整合mybatis报错：Invalid bound statement (not found):

最近没写ssm项目了，自己重新搭建项目在spring整合mybatis的时候，报错如下信息，忘记怎么解决了

原因：

检查了好久，所有的namespace ，等配置都没有问题，后来找了半天，发现在编译之后的xml文件没有被加载；在编译之后的target文件夹中没有对应的xml文件，所以导致的

解决方案：

找到pom文件，添加下面代码

		
            
                src/main/java
                
                    **/*.xml
                
            
        

再看下编译之后的target文件夹
