Geoserver 2.18.4 解決跨域問題

1.Geoserver的安裝

Geoserver安裝包下載下傳位址：http://geoserver.org/release/maintain/。下載下傳的是windows安裝版。

 安裝完成後，啟動geoserver。在浏覽器打開 http://localhost:8080/geoserver/web/，預設賬号：admin   預設密碼：geoserver 

 2.jar包拷貝

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

把3個jar包拷貝到geoserver\webapps\geoserver\WEB-INF\lib\目錄下；

 3.修改web.xml檔案

去geoserver\webapps\geoserver\WEB-INF目錄下找web.xml,進行如下修改：

• 添加如下内容，若是有，可以直接取消注釋

<!-- 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>
