Spring 4.1.1 WebSocket Stomp子協議錯誤

Question

我們試圖將我們的項目之一從Spring 4.0.7.RELEASE遷移到4.1.1.RELEASE。 之後，我們得到以下錯誤。

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

我們沒有的配置改變任何東西（而不能發現，我們必須改變任何暗示）。

這是我們的WebSockets的服務器端配置。 （它實際上和Spring文檔中的一樣）。

@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"); 
} 
} 

而且我們對每個類似下面的方法之前描述的端點：從JavaScript

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

客戶端調用看起來像下面這樣：

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

是否有人有一個想法，有什麼變化讓我們陷入困境，以及如何解決這個問題？

非常感謝。

Answer 1

首先它真的是bug。謝謝你指出！

我們提出了一個問題（https://jira.spring.io/browse/SPR-12403），它將在下週內修復。

在此之前，你難道不能用單一的端點克服單塊端點的惡意映射嗎？

UPDATE

我得到它告訴我，協議跺腳1.0，1.1和1.2都已經映射

因爲我們確實有一個問題在這裏一個錯誤，你需要克服它不知何故，我建議你嘗試越過豆：

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

與您的自定義實現，whe addProtocolHandler將有一個空的身體，因爲你說你已經定義了STOMP作爲默認值。有了該框架將無法添加更多SubProtocolHandler s。
