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>
