氛围+ Tomcat 8和非Atmosphere客户端的泽西错误

Question

我运行一个使用Atmosphere作为websocket支持框架的聊天服务器。大气使用泽西岛，因为我使用的气氛泽西maven依赖。

聊天服务器在Tomcat 7中运行，我们正在升级到Tomcat 8

我们的一个客户用泰鲁斯 - 作为他们的Java API的WebSocket。

当我们的聊天服务器部署在Tomcat 7上（Java 6,7或8）时，没有任何问题。

通过Tomcat 8（Java 8）上的聊天服务器，我们使用Atmosphere的测试客户端运行正常，但使用Tyrus的客户端却没有。我们所看到的错误是：

这是因为在Tomcat 7，从WebSocket的请求的请求的URL被视为类似的“http：//本地主机：8080 /聊天/”（请求是由到ws：// localhost：8080/chat /，但它已更改为http：// somewhere）。但是对于Tomcat 8，来自websocket请求的请求URL与“/ chat /”类似，并且模式不存在，Jersey会引发错误。

为了解决这个问题，Atmosphere会在Atmosphere客户端发出请求时查找包含模式的标题“origin”。但是，当一个Tyrus客户端发出请求时，这个“origin”头文件不包含导致上面显示的错误的http模式。

我想知道是否有人有任何想法为此简单的解决方案或碰到类似的问题。我做了很多搜索简单的解决方案，但还没有找到。没有人，我们正在考虑不得不停止使用Atmosphere并使用其他代码重构的其他内容。

这些是关于这个问题的票据/错误的一些链接，似乎已经解决了这个问题，但我有正确的版本，仍然有问题。

这种情况的解决方法是改变“原始“标题，并添加http：//模式（如果它不存在）。本文帮着想出来的：Modify request parameter with servlet filter

import java.io.IOException; 
import java.util.Collections; 
import java.util.Enumeration; 
import javax.servlet.*; 

public class FixSchemaFilter implements Filter { 

    @Override 
    public void init(FilterConfig filterConfig) throws ServletException {} 

    @Override 
    public void destroy() {} 

    @Override 
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { 
     if (request instanceof HttpServletRequest) { 
      chain.doFilter(new FixSchemaHttpServletRequest((HttpServletRequest) request), response); 
     } else { 
      chain.doFilter(request, response); 
     } 
    } 

    public class FixSchemaHttpServletRequest extends HttpServletRequestWrapper { 

     public FixSchemaHttpServletRequest(HttpServletRequest request) { 
      super(request); 
     } 

     @Override 
     public String getHeader(String header) { 
      String value = super.getHeader(header); 
      if (header.equalsIgnoreCase("origin") && !value.startsWith("http://")) { 
       return "http://" + value; 
      } 
      return value; 
     } 

     @Override 
     public Enumeration getHeaders(String header) { 
      Enumeration enumeration = super.getHeaders(header); 
      if (header.equalsIgnoreCase("origin") && super.getHeader(header) != null && !super.getHeader(header).startsWith("http://")) { 
       return Collections.enumeration(Collections.singleton(getHeader(header))); 
      } 
      return enumeration; 
     } 
    } 

} 

然后将过滤器添加到web.xml

<filter> 
     <filter-name>FixSchemaFilter</filter-name> 
     <filter-class>com.example.FixSchemaFilter</filter-class> 
</filter> 
<filter-mapping> 
     <filter-name>FixSchemaFilter</filter-name> 
     <url-pattern>/*</url-pattern> 
</filter-mapping>
