直接在pom.xml文件中加入下列对应的文件格式到<build>即可，如果其他后缀文件也是

读取不到，那么在<includes></includes>中新增<include>**/*.properties</include>即可。

<build>
    <!--扫描到resources下的xml等资源文件-->
    <resources>
      <resource>
        <directory>src/main/java</directory>
        <includes>
          <include>**/*.xml</include>
        </includes>
        <filtering>true</filtering>
      </resource>
      <resource>
        <directory>src/main/resources</directory>
        <includes>
          <include>**/*.xml</include>
        </includes>
        <filtering>true</filtering>
      </resource>
    </resources>
</build>
