将下面代码粘贴到pom文件里build里即可

<build>
<resources>
      <resource>
        <!--表示需要编译的源文件路径-->
        <directory>src/main/java</directory>
        <includes>
          <!--表示以.properties和*.xml结尾的文件将进行编译-->
          <include>**/*.properties</include>
          <include>**/*.xml</include>
        </includes>
        <filtering>false</filtering>
      </resource>

             <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
            </resource>
    </resources>
</build> 

 然后重新compile一下就可以在target/classes下看到了
