Spring 4.1.1 WebSocket Stomp子协议错误

Question

我们试图将我们的项目之一从Spring 4.0.7.RELEASE迁移到4.1.1.RELEASE。 之后，我们得到以下错误。

java.lang.IllegalStateException: Multiple protocol handlers configured and no protocol was negotiated. Consider configuring a default SubProtocolHandler.

我们没有的配置改变任何东西（而不能发现，我们必须改变任何暗示）。

这是我们的WebSockets的服务器端配置。 （它实际上和Spring文档中的一样）。

@Configuration 
@EnableWebSocketMessageBroker 

public class WebSocketConfiguration extends AbstractWebSocketMessageBrokerConfigurer { 

@Override 
public void registerStompEndpoints(final StompEndpointRegistry registry) { 
    registry.addEndpoint("/tyresearch").withSockJS(); 
    registry.addEndpoint("/tyresearch/changeConfiguration").withSockJS(); 
    registry.addEndpoint("/tyresearch/detailView").withSockJS(); 
} 

@Override 
public void configureMessageBroker(final MessageBrokerRegistry config) { 
    config.enableSimpleBroker("/topic"); 
    config.setApplicationDestinationPrefixes("/app"); 
} 
} 

而且我们对每个类似下面的方法之前描述的端点：从JavaScript

@MessageMapping("/tyresearch") 
public void startTyreSearch(@Payload final TyreSearchRequestContainerDto message, final Principal user, final StompHeaderAccessor) { 
    .... 
} 

客户端调用看起来像下面这样：

var socket = new $wnd.SockJS('/server/api/rest/tyresearch'); 
    var stompClient = $wnd.Stomp.over(socket); 
    stompClient.connect({}, function(frame) { 
     console.log('Connected: ' + frame); 
    }); 

是否有人有一个想法，有什么变化让我们陷入困境，以及如何解决这个问题？

非常感谢。

Answer 1

首先它真的是bug。谢谢你指出！

我们提出了一个问题（https://jira.spring.io/browse/SPR-12403），它将在下周内修复。

在此之前，你难道不能用单一的端点克服单块端点的恶意映射吗？

UPDATE

我得到它告诉我，协议跺脚1.0，1.1和1.2都已经映射

因为我们确实有一个问题在这里一个错误，你需要克服它不知何故，我建议你尝试越过豆：

@Bean 
    public WebSocketHandler subProtocolWebSocketHandler() { 
     return new SubProtocolWebSocketHandler(clientInboundChannel(), clientOutboundChannel()); 
    } 

与您的自定义实现，whe addProtocolHandler将有一个空的身体，因为你说你已经定义了STOMP作为默认值。有了该框架将无法添加更多SubProtocolHandler s。
