此问题有两种情况：

• 为Mabatis绑定错误
• IDEA打包问题（如果在eclipse下面没有该问题，在IDEA存在，需要在pom.xml下面加上*Mapper.xml配置一起打包）

Mybatis绑定错误解决方案

一般的原因是Mapper interface和xml文件的定义对应不上，需要检查包名，namespace，函数名称等能否对应上，需要比较细致的对比，我经常就是写错了一两个字母搞的很长时间找不到错误

按以下步骤一一执行：

1. 检查xml文件所在的package名称是否和interface对应的package名称一一对应
2. 检查xml文件的namespace是否和xml文件的package名称一一对应
3. 检查函数名称能否对应上
4. 去掉xml文件中的中文注释
5. 随意在xml文件中加一个空格或者空行然后保存

一般来说到此就可以排除错误了

IDEA存在该问题，但是eclipse正常

maven默认会把src/main/resources下的所有配置文件以及src/main/Java下的所有java文件打包或发布到target\classes下面，但是现实我们可能会在src/main/java下面也放置一些配置文件如hibernate配置文件或mybatis mapper配置文件等，如果不做一些额外配置，那我们打包后的项目可能找不到这些必须的资源文件，因此在pom.xml中增加类似如下配置：

<resources>
   <resource>
      <directory>src/main/java</directory>
      <includes>
         <include>**/*.xml</include>
      </includes>
   </resource>
   <resource>
      <directory>src/main/resources</directory>
   </resource>

</resources> 

就会将src/main/java下的xml文件随同java编译后的class文件一同copy到相应的class目录
