你好，我有一个Spring MVC 4.0.4项目完全配置使用Wildfly 8.1服务器内的注释，唯一的问题是当我使用以下javascript代码初始化Sockjs使用Stompjs我得到一个异常，我不明白，为了清楚这不会发生当我使用基于XML的配置，我使用这个链接中的教程
Javascript代码var socket = new SockJS('/frontend/track');
referencesServices.stompClient = Stomp.over(socket);
webscket java config
@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");
}
}

现在在smoky的帮助下，websocket最终在wildfly 8上工作，现在唯一的问题是当sockjs连接时抛出异常:

在op:
首先，您需要使用最近的底层库。有两种可能，但我只测试了第一个:
-
更新
modulessystemlayersbaseioundertow的底层库:我只从1.0.15更新了
core和servlet。最终版本为1.1.0。Beta3然后更新两个module.xml以使用新文件。 -
在你的项目中使用新的底层库(例如w/Maven)，并使用
jboss-deployment-structure.xml禁用模块。
XML应该是这样的:
<?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>
第二，在web.xml中，您需要将<async-supported>true</async-supported>添加到DispatcherServlet 和过滤器(如果使用)。
事实上，这看起来像是一个Wildfly问题(参见HttpServletResponse.getHeaders中的WFLY-3474 - NPE)。
升级到最近的Undertow版本(1.1.0)Beta2 +)解决了这个特定的异常，但产生了一个更大的问题，因为Spring框架websocket模块还不支持这个测试版。
SPR-11919应该能解决你的第一个问题。
遵循SPR-11914获得即将到来的undertow 1.1支持。
我的印象是服务器和客户端不能相互通信(错误造成的说: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)。
我认为这是因为SockJS的路径在客户端和服务器端不一样。事实上，javascript sockJS的值是'/前端/轨道' (var socket = new SockJS('/frontend/track'))，而它只是'轨道'在服务器端(registry.addEndpoint("/track").withSockJS())。如果我已经很好地理解了spring文档，在SockJS中声明的路径在服务器和客户端(javascript)方面应该是相同的，但我可能会犯一个错误…
