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:

   HTTP/1.1 200X-Frame-Options: SAMEORIGINX-Content-Type-Options: nosniffgeowebcache-tile-index: [13591, 9726, 14]Cache-Control: no-cache, no-store, must-revalidatePragma: no-cacheExpires: 0geowebcache-cache-result: HITgeowebcache-tile-index: [13591, 9726, 14]geowebcache-tile-bounds: 13205872.500935059,3752140.8439404294,13208318.485839844,3754586.828845214geowebcache-gridset: EPSG:3857geowebcache-crs: EPSG:3857Last-Modified: Wed, 08 Jan 2025 03:40:58 GMTContent-Disposition: inline; filename=geoserver-dispatch.imageContent-Type: image/pngContent-Length: 188615Date: Thu, 27 Feb 2025 05:48:49 GMTKeep-Alive: timeout=20Connection: keep-alive

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

<!-- 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

   <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>
