GeoServer解决跨域

需要使用geoserver rest在前端进行服务发布，所以解决geoserver跨域问题。

一、windwos安装包2.21.0版本Geoserver解决跨域（测试，可行）

打开geoserver\webapps\geoserver\WEB-INF下的web.xml文件。

去掉注释，在bin文件夹下startup.bat重启即可。

<!-- Uncomment following filter to enable CORS in Jetty. Do not forget the second config block further down.-->
    <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>

二、tomcat部署的独立版本geoserver跨域（未测试）。

打开geoserver\webapps\geoserver\WEB-INF下的web.xml文件。重启geoserver。

<!-- Uncomment following filter to enable CORS in Tomcat. Do not forget the second config block further down.
    <filter>
      <filter-name>cross-origin</filter-name>
      <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
      <init-param>
        <param-name>cors.allowed.origins</param-name>
        <param-value>*</param-value>
      </init-param>
      <init-param>
        <param-name>cors.allowed.methods</param-name>
        <param-value>GET,POST,PUT,DELETE,HEAD,OPTIONS</param-value>
      </init-param>
      <init-param>
        <param-name>cors.allowed.headers</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>
