geoserver rest接口跨域访问

我用的2.12.2版本，访问rest接口时遇到了跨域问题，参考http://blog.csdn.net/qq_29176825/article/details/77968307等文章时，发现源码文件中自带了跨域功能，只是默认没有启用。

找到geoserver-2.12.2\src\web\app\src\main\webapp\WEB-INF\web.xml中

<!-- Uncomment following filter to enable CORS -->

   <!-- <filter>

        <filter-name>cross-origin</filter-name>

        <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>

    </filter> -->

   <!-- Uncomment following filter to enable CORS -->

    <!-- <filter-mapping>

        <filter-name>cross-origin</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping> -->

放开注释，修改为

   <filter>

        <filter-name>cross-origin</filter-name>

        <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
