Geoserver 2.18.4 解决跨域问题

1.Geoserver的安装

Geoserver安装包下载地址：http://geoserver.org/release/maintain/。下载的是windows安装版。

 安装完成后，启动geoserver。在浏览器打开 http://localhost:8080/geoserver/web/，默认账号：admin   默认密码：geoserver 

 2.jar包拷贝

去geoserve的lib目录下 geoserver\lib找jetty-servlets-XX.jar , jetty-util-xx.jar，jetty-http-XX.jar(xx表示不同的版本)3个jar包；

把3个jar包拷贝到geoserver\webapps\geoserver\WEB-INF\lib\目录下；

 3.修改web.xml文件

去geoserver\webapps\geoserver\WEB-INF目录下找web.xml,进行如下修改：

• 添加如下内容，若是有，可以直接取消注释

<!-- Uncomment following filter to enable CORS -->
   <filter>
        <filter-name>cross-origin</filter-name>
        <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
       <init-param>
           <param-name>chainPreflight</param-name>
           <param-value>false</param-value>
       </init-param>
       <init-param>
           <param-name>allowedOrigins</param-name>
           <param-value>*</param-value>
       </init-param>
       <init-param>
           <param-name>allowedMethods</param-name>
           <param-value>GET,POST,PUT,DELETE,HEAD,OPTIONS</param-value>
       </init-param>
       <init-param>
           <param-name>allowedHeaders</param-name>
           <param-value>*</param-value>
       </init-param>
    </filter>
    
    
<!-- Uncomment following filter to enable CORS  -->
    <filter-mapping>
        <filter-name>cross-origin</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
