java - jetty 跨源过滤器

Question

我已经配置了 Jetty 的跨域过滤器，但我仍然收到以下错误。有谁知道出了什么问题以及如何解决？错误消息下方是我的覆盖描述符(即补充 web.xml)

错误:

Origin http://localhost:8090 is not allowed by Access-Control-Allow-Origin.

覆盖描述符:

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>

 </filter>
 <filter-mapping>
     <filter-name>cross-origin</filter-name>
     <filter-pattern>/*</filter-pattern>
 </filter-mapping>
</web-app>

Answer 1

阿罗哈，

我也为此奋斗了一段时间，发现最终节点需要是:

<filter-mapping>
    <filter-name>cross-origin</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

不是

<filter-mapping>
     <filter-name>cross-origin</filter-name>
     <filter-pattern>/*</filter-pattern>
</filter-mapping>

这是我找到的对我有帮助的链接:wiki.eclipse.org/Jetty/Feature/Cross_Origin_Filter

在我更新了 web.xml 文件并重新启动了 jetty 服务器后，我能够使用 jQuery ajax 调用进行跨域请求。
