具体的出错如图:

将.xml的的mapper文件引入即可解决.

具体可以通过修改pom文件解决

解决办法:

打开pom文件,在<build>标签中添加配置文件路径,以及需要发布的文件后缀名

<build>

  	    <!-- 解决mapper映射文件不发布问题 -->
  	  	<resources>
  		<resource>
  			<directory>src/main/java</directory>
  			<includes>
  				<include>**/*.xml</include>
  			</includes>
  		</resource>
  			<resource>
  			<directory>src/main/resources</directory>
  			<includes>
  				<include>**/*.properties</include>
  				<include>**/*.xml</include>
  			</includes>
  		</resource>
  	</resources>
  </build>

重启工程,再看发布.classes目录

即可解决
