一、去geoserve的lib目录下 geoserver\lib找jetty-servlets-XX.jar , jetty-util-xx.jar(xx表示不同的版本)两个jar包；
二、把两个jar包拷贝到geoserver\webapps\geoserver\WEB-INF\lib\目录下；
三、去geoserver\webapps\geoserver\WEB-INF目录下找web.xml,进行如下修改：
<!-- Uncomment following filter to enable CORS in Jetty. Do not forget the second config block further down.

</filter>
- 去找<filter-mapping>的平级标签，加上以下内容：
<filter-mapping>
<filter-name>cross-origin</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
四、完整版web.xml
