独特的令人困惑的JBoss resteasy错误 - 无法找到资源

标签： java apache rest jboss httpd.conf

我通过负载均衡的Web服务器（2个Web服务器转发请求到两个应用服务器）访问其他URL时遇到问题。当设置为单个Web服务器到单个jboss应用服务器时，不会发生此问题。

以下是我从jBoss应用程序服务器日志中看到的错误消息：

16:02:46,711 DEBUG [org.jboss.resteasy.core.SynchronousDispatcher] (http-/30.31.32.33:8080-14) PathInfo: //AppName/rest/game/userStatus

        GameService gs = new GameService();
        return gs.getUserReportStatus(userId);
    }
}

以下是web.xml的主要内容：

我期望的结果是：

{"status":"Yes","dob":"01/01/1934","userName":"John Doe","reportStatus":"No"}

在向app服务器的ip地址发出请求时，我收到了上述正确的结果 http://30.31.32.33:8080/AppName/rest/game/userStatus?userId=99984029883634

通过负载平衡Web服务器时得到的实际结果是：

HTTP Status 404 - Could not find resource for relative : //AppName/rest/game/userStatus of full path: http://stg.testing.com//AppName/rest/game/userStatus?userId=99984029883634

在向Web服务器URL发出请求时，我收到了上述结果。 http://stg.testing.com/AppName/rest/game/userStatus?userId=99984029883634

  

注意：我通过将stg.testing.com分配给Web服务器ip进行测试   主机文件中的地址。

以下是httpd.conf文件中w.r.t设置app服务器名称/ IP地址出现的位置。

我使用jboss 7.1.2作为我的app服务器，使用apache作为web服务器。此Rest应用程序在后端使用axis soap webservice客户端。因此我在web.xml中有与轴相关的语句。我已经验证了soap客户端在两种情况下都能正常工作。 我不确定这是由于Web服务器问题（在AppName之前自动添加2个正斜杠）还是jboss问题，如列出的here ，here  和here 我已经尝试了以上三个jboss修复建议，但仍然有相同的错误。 任何帮助确定我的错误原因都会很棒。

更新：我尝试将servlet插入到上下文根目录下的单独目录中，并且可以从负载均衡器访问servlet。所以现在我假设这是一个软件问题而不是硬件问题。此外，在每个日志的请求期间调用org.jboss.resteasy.core.SynchronousDispatcher，我假设它不是404而是导致双正斜杠的内部重定向。任何帮助都会有用。提前谢谢。

今天我们发现了这个问题。 该问题是由httpd.conf

中的BalancerMember URL语句中的额外“/”引起的

现在，BalancerMember网址声明已更改为

<Proxy balancer://stgsilo stickysession=JSESSIONID>
   BalancerMember http://30.31.32.33:8080 min=10 max=100 route=node1 loadfactor=1
