解决：
在检查了所有的配置之后，发现名称、位置这些都没问题，那么问题在哪呢？
可以看到我的mapper.xml并没有放在resources文件夹里面
这时候有两种方法：
1、把*.xml放到resources里面
2、在maven的pom.xml中加上
1 <build> 2 <resources> 3 <resource> 4 <directory>src/main/java</directory> 5 <includes> 6 <include>**/*.xml</include> 7 </includes> 8 <filtering>false</filtering> 9 </resource> 10 </resources> 11 </build>
