CORS过滤器tomcat 7请求的资源上没有"Access-Control-Allow-Origin"标头

Question

我在tomcat7 conf/web.xml中使用以下配置

<filter>
 <filter-name>CorsFilter</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,HEAD,OPTIONS,PUT</param-value>
 </init-param>
 <init-param>
  <param-name>cors.allowed.headers</param-name>
  <param-value>Content-Type,X-Requested-With,accept,Origin,Access-Control-Request-Method,Access-Control-Request-Headers, Last-Modified</param-value>
 </init-param>
 <init-param>
  <param-name>cors.exposed.headers</param-name>
  <param-value>Access-Control-Allow-Origin,Access-Control-Allow-Credentials</param-value>
 </init-param>
 <init-param>
  <param-name>cors.support.credentials</param-name>
  <param-value>true</param-value>
 </init-param>

</filter>
<filter-mapping>
 <filter-name>CorsFilter</filter-name>
 <url-pattern>/*</url-pattern>
</filter-mapping>

我的apache webserver向tomcat rest api发送请求.APache webserver在端口8005上运行,tomcat在8080上运行.因此请求从mydomain.com:8085/index.php/kop发送到mydomain.com:8080/webiste-1.0/rest-api/product.我正进入(状态

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://x.x.x.x:8085' is    therefore not allowed access.

以下是chrome的请求标头:

Accept:application/json, text/javascript, */*; q=0.01
Cache-Control:no-cache
Origin:http://x.x.x.x:8085
Pragma:no-cache
Referer:http://x.x.x.x:8085/html/index.php/kop_och_salj
User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.153    Safari/537.36

我究竟做错了什么？我错过了什么吗？

我自己找到了解决方案。Apache Tomcat 包含对 CORS 的支持 - 从 Tomcat 版本 7.0.41 开始 - 我的问题是我在 ubuntu 12.04 版本上使用 apt-get install tomcat7 安装了 tomcat 7，并且安装了比 7.0.41 更旧的版本。一旦我手动安装了tomcat 7.0.54，cors过滤器就起作用了
