原因

pom.xml文件默认不拷贝到class路径下，

解决方法

修改taotao-manager-mapper的pom文件

在pom文件中添加如下内容：

<!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 -->       <build>             <resources>             <resource>                 <directory>src/main/java</directory>                 <includes>                     <include>**/*.properties</include>                     <include>**/*.xml</include>                 </includes>                 <filtering>false</filtering>             </resource>         </resources>       </build>
