將下面代碼粘貼到pom文件里build里即可

<build>
<resources>
      <resource>
        <!--表示需要編譯的源文件路徑-->
        <directory>src/main/java</directory>
        <includes>
          <!--表示以.properties和*.xml結(jié)尾的文件將進(jìn)行編譯-->
          <include>**/*.properties</include>
          <include>**/*.xml</include>
        </includes>
        <filtering>false</filtering>
      </resource>
    </resources>
</build> 

?然后重新compile一下就可以在target/classes下看到了
