我用的是Intellij idea开发Spring+maven+mybatis，根据上面报错，是因为找不到xml文件，但是我的xml文件和路径都是对的，而且存在，为什么找不到呢？
后来发现，编译后的文件夹target中的class里，并没有mapping文件夹，更没有xml。那么问题就很清楚了，是Intellij idea导致不把xml编译进去，之前使用MyEclipse并没遇到这个问题。
解决办法是：须在pom.xml文件中添加如下配置(来源：http://blog.youkuaiyun.com/u012599988/article/details/44041205)

<build>
<finalName>API</finalName>
<resources>
······
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
······
</resources>
</build>
