Spring Boot，Websockets无法从Session获取用户（即java.security.Principal）

与...一起工作Spring Boot 1.2.1.RELEASE and Spring Websockets。运行嵌入式时存在部署运行时问题Jetty 9，我不能伪造用户（java.security.Principal）当应用程序部署在本地主机以外的其他地方时成功。

我咨询过

• http://docs.spring.io/spring/docs/current/spring-framework-reference/html/websocket.html#websocket-stomp-authentication http://docs.spring.io/spring/docs/current/spring-framework-reference/html/websocket.html#websocket-stomp-authentication
• http://docs.spring.io/spring/docs/current/spring-framework-reference/html/websocket.html#websocket-server-runtime-configuration http://docs.spring.io/spring/docs/current/spring-framework-reference/html/websocket.html#websocket-server-runtime-configuration

下面的配置（我相信）已经“升级”了请求

@Configuration
@EnableWebSocketMessageBroker
@EnableScheduling
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
    // see http://docs.spring.io/spring/docs/current/spring-framework-reference/html/websocket.html#websocket-stomp-handle-broker-relay
    // requires an external broker like AMQP or RabbitMQ
    //registry.enableStompBrokerRelay("/queue/", "/topic/");

    // XXX This might wind up being the impl we actually deploy; but be aware it has certain constraints
    // see http://docs.spring.io/spring/docs/current/spring-framework-reference/html/websocket.html#websocket-stomp-message-flow
    registry.enableSimpleBroker("/queue/", "/topic/");
    registry.setApplicationDestinationPrefixes("/app");
}

@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
    registry.addEndpoint("/cards").setHandshakeHandler(new UserHandler()).withSockJS();
}

// cheat; ensure that we have a Principal w/o relying on authentication
class UserHandler extends DefaultHandshakeHandler {

    @Override
    protected Principal determineUser(ServerHttpRequest request, WebSocketHandler wsHandler,
                    Map<String, Object> attributes) {
        return new TestPrincipal("bogus");
    }
}

这是校长...

public class TestPrincipal  implements Principal {

private final String name;


public TestPrincipal(String name) {
    this.name = name;
}

@Override
public String getName() {
    return this.name;
}

}

但这是我收到的例外......

这里我还应该考虑什么？

UPDATE

我现在可以在本地主机部署中可靠地重现这一点。

有趣的是，使用STS 3.6.3在调试模式下，当我在第 91 行设置断点时JettyRequestUpgradeStrategy

public JettyRequestUpgradeStrategy(WebSocketServerFactory factory) {
    Assert.notNull(factory, "WebSocketServerFactory must not be null");
    this.factory = factory;
    this.factory.setCreator(new WebSocketCreator() {
        @Override
        public Object createWebSocket(ServletUpgradeRequest request, ServletUpgradeResponse response) {
            // Cast to avoid infinite recursion
            return createWebSocket((UpgradeRequest) request, (UpgradeResponse) response);
        }

然后继续到第 41 行设置的另一个断点PrincipalMethodArgumentResolver

@Override
public Object resolveArgument(MethodParameter parameter, Message<?> message) throws Exception {
    Principal user = SimpMessageHeaderAccessor.getUser(message.getHeaders());
    if (user == null) {
        throw new MissingSessionUserException(message);
    }
    return user;
}

the user is null。是否存在竞争条件？例如，套接字必须从请求中获取用户是否有一定的时间限制？
