请求Geoserver的WTMS服务返回200不返回图片问题-跨域导致

今天碰到个奇怪问题，改了个页面标题再打包布署GeoServer发现调用WTMS服务失败，请求返回状态码200，返回包大小0，使用postman模拟请求是可以正常返回图片的。

跟之前版本对比如下：

正常Response请求:

发现异常中没有：Access-Control-Allow-Origin

才想起来之前好像配置过跨域：

修改跨域：web.xml

注意如果按deepseek推荐使用org.eclipse.jetty.servlets.CrossOriginFilter这个类需要添加jar包（jetty-servlets-9.4.56.v20240826.jar, jetty-util-9.4.56.v20240826.jar）

下面我推荐tomcat的，不用加jar包

xml 复制代码

<!-- 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-mapping to enable CORS -->
    <filter-mapping>
        <filter-name>cross-origin</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

完了记录清理Tomcat缓存：apache-tomcat-8.5.99\work\Catalina\localhost

重启Tomcat就可以正常使用。

如果需要修改缓存目录，修改geoserver中web.xml，增加

xml 复制代码

   <context-param>
      <param-name>GEOSERVER_DATA_DIR</param-name>
       <param-value>E:\map\geoserver-2.15.0\webapps\geoserver\data</param-value>
   </context-param>
   <context-param>
      <param-name>GEOWEBCACHE_CACHE_DIR</param-name>
      <param-value>E:\map\geoserver-2.15.0\cache</param-value>
    </context-param>
