Tomcat8和非Atmosphere客户端出现Atmosphere+Jersey错误

Question

我运行了一个聊天服务器，它使用Atmosphere作为websocket支持的框架。Atmosphere使用Jersey是因为我使用atmosphere jersey maven依赖项。

聊天服务器在Tomcat7上运行，我们正在升级到Tomcat8。

我们的一个客户使用Tyrus作为他们的Java websocket API。

当我们的聊天服务器部署在Tomcat7(使用Java6、7或8)上时，没有问题。

在Tomcat8 (Java 8)上使用我们的聊天服务器时，使用Atmosphere的测试客户端工作得很好，但是使用Tyrus的客户端就不行了。我们看到的错误是：

这是因为在Tomcat7中，来自websocket请求的请求URL类似于"http:// localhost:8080/chat/“(向ws://localhost:8080/chat/发出请求，但它已更改为http://某处)。但是在Tomcat8中，来自websocket请求的请求URL类似于"/chat/“，模式不在那里，Jersey抛出一个错误。

为了解决这个问题，Atmosphere在Atmosphere客户端发出请求时查找报头"origin“，它具有模式。但是当Tyrus客户端发出请求时，"origin“报头不包括http schema，从而导致上面显示的错误。

我想知道是否有人对此有任何简单的解决方案，或者遇到过类似的问题。我已经做了很多寻找一个简单的解决方案，但还没有找到一个。如果没有一个，我们将不得不停止使用are，而使用其他一些东西，这就是大量的代码重构。

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

Atmosphere版本: 2.4.8

泽西版本(通过大气)：1.19

Tyrus版本: 1.13

此问题的解决方法是通过过滤器更改"origin“标头，如果http://模式不存在，则添加它。这篇文章帮助我们解决了这个问题：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>
