使用Sockjs和Stompjs的Spring MVC和Websocket异常

javajavascriptspring-mvcwebsocketspring-websocket
4
你好，我有一个完全配置了注释的Spring MVC 4.0.4项目，在Wildfly 8.1服务器中运行。唯一的问题是当我使用以下javascript代码初始化Sockjs时，会出现一个我不理解的异常。为了清晰起见，当我使用基于XML的配置时，这种情况并没有发生。我使用了这个链接中的教程。 Javascript 代码： 
var socket = new SockJS('/frontend/track');
referencesServices.stompClient = Stomp.over(socket);

Websocket Java配置

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
    public static final Logger LOGGER = LogManager.getLogger(WebSocketConfig.class); 

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        LOGGER.debug("INIT WEBSOCKET END POINTS");
        registry.addEndpoint("/track").withSockJS();//.setDisconnectDelay(30000);
    }

    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
        registry.enableSimpleBroker("/updates");
//      registry.enableStompBrokerRelay("/queue/", "/topic/");
        registry.setApplicationDestinationPrefixes("/app");
    }

}

异常

更新

现在在smoky的帮助下，websocket已经可以在wildfly 8上运行了，现在唯一的问题是当sockjs连接时会抛出异常：

Weboscket sockjs 错误

其实我也遇到了同样的问题。我发现这个问题来自于io.undertow.servlet.spec.HttpServletResponseImpl，它使用了io.undertow.util.HeaderMap，返回了null并导致了NullPointerException。这个库是Wildfly原生的。但我还没有找到任何解决方案。 - Ludovic Guillaume
那么解决方案就是将服务器更改为Tomcat 8，例如？ - Diego Fernando Murillo Valenci
实际上，这在Glassfish 4上运行正常。因此，我猜这是Wildfly的一个错误。我认为可以通过使用Spring 4.0.5修改AbstractSockJsService中的第366行来绕过此问题。我正在寻找解决方案。 - Ludovic Guillaume
如果我使用Maven更改undertow-servlet并使用jboss-deployment-structure排除模块，你觉得怎么样？你知道我可以排除哪个模块以及在我的pom中包含哪些jar吗？ - Diego Fernando Murillo Valenci
@DiegoFernandoMurilloValenci，你能为你的更新问题开一个新的提问吗？这个问题与之前的无关，应该对其他人有帮助。当完成时通知我，我可能能够帮助你解决这个问题。 - Brian Clozel

通过op的帮助：

首先，您需要使用最近的undertow库。有两种可能性，但我只测试了第一种：

  1. 更新modules\system\layers\base\io\undertow\中的undertow libs：

    我只将core和servlet从1.0.15.Final更新到1.1.0.Beta3，然后更新了两个module.xml文件以使用新文件。

  2. 在项目中使用新的undertow libs（例如使用Maven），并使用jboss-deployment-structure.xml禁用模块。

XML应该如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="io.undertow.core" />
            <module name="io.undertow.servlet" />
        </exclusions>
</deployment>
</jboss-deployment-structure>

其次，在web.xml中，您需要向DispatcherServlet 和过滤器（如果使用）添加<async-supported>true</async-supported>。
谢谢，我正在尝试第二次尝试，但是出现了相同的错误。我正在使用Java配置，所以不知道在哪里将async-support设置为我的过滤器，我使用AbstractAnnotationConfigDispatcherServletInitializer作为我的Web初始化程序（替换为web.xml），并且在customizeRegistration方法中使用setAsyncSupported(true)，但是我不知道在我的AbstractSecurityWebApplicationInitializer（替换为<filter-name>springSecurityFilterChain</filter-name>）中设置异步，因此我认为如果没有这个选项，两个选项都对我无效，我可以看到异常中的undertow版本更改。 - Diego Fernando Murillo Valenci
我添加了我的应用程序初始化器代码，其中我设置了异步支持。 - Diego Fernando Murillo Valenci
我使用你提供的第一种选项，但我的视图解析器不再工作了，也许所有问题都是因为我使用了Java配置而不是XML，我在Glassfish中尝试了我的项目，它像魔法一样运行良好，所以现在我使用Glassfish，很高兴这对你有用。 - Diego Fernando Murillo Valenci
我不知道如何处理非XML定义。我已将async-support设置为filter和servlet的子项在web.xml中。在Java配置中应该有一个替代方案。实际上，我的第一个目标是从Glassfish迁移到Wildfly，因为将来缺乏支持。 - Ludovic Guillaume
最终我在Wildfly 8中使用第一种选项使其工作了，我想我替换的是beta1而不是beta3，这就是问题所在，现在WebSocket在我的项目中可以工作了，唯一的问题是当WebSocket启动时会抛出一个异常，我将更新我的问题以展示它。 - Diego Fernando Murillo Valenci
非常感谢，方法1对我有用！当客户端发送异步请求时，Undertow会抛出异常，升级库可以解决这个问题。 - cpandey05

实际上，这似乎是一个Wildfly问题（请参见WFLY-3474 - HttpServletResponse.getHeaders中的NPE）。

升级到最新的Undertow版本（1.1.0.Beta2+）可以解决特定的异常，但会引起更大的问题，因为Spring Framework websocket模块尚不支持此beta版本。

SPR-11919应该解决您的第一个问题。

请关注SPR-11914以获得即将推出的undertow 1.1支持。

我将为此添加一个新问题，您认为这个问题会在Wildfly 9版本和Spring的下一个版本中得到解决吗？我正在使用Spring 4.0.5。 - Diego Fernando Murillo Valenci

我认为在Wildfly 9中会随着修复而发布undertow。与此同时，你可以在Spring Framework 4.0.6发布后（几天内）使用非测试版的undertow版本。 - Brian Clozel
其实，不用再添加另一个问题了 - 除非您认为Wildfly用户经常尝试将Undertow升级到Beta版本？ - Brian Clozel
正如@BrianClozel所提到的，这适用于Spring Framework 4.0.6和非beta版本的Undertow。谢谢。 - Ludovic Guillaume

我有这样的印象，即服务器和客户端无法相互通信（错误信息为：Caused by: org.springframework.web.socket.sockjs.SockJsException: Uncaught failure in SockJS request, uri=http://localhost:8080/frontend/track/info; nested exception is java.lang.NullPointerException）。

我认为这是由于SockJS的路径在客户端和服务器端不同造成的。实际上，javascript sockJS的值为'/frontend/track'（var socket = new SockJS('/frontend/track')），而在服务器端只是'\track'（registry.addEndpoint("/track").withSockJS()）。如果我正确理解了Spring文档，SockJS在服务器和客户端（javascript）端声明的路径应该相同，但我可能犯了一个错误...

谢谢您的回答，但路径是正确的，因为如果我更改它，错误将是404而不是像我这种情况下的500，这是服务器错误。 - Diego Fernando Murillo Valenci
你能否展示一下之前使用的XML代码，包括所有配置文件以及设置调度器和监听器的其他Java代码类？谢谢。 - EPerrin95
