弹簧 websocket 遇到"Ignoring message, no principal info available"错误

Question

我正在使用spring 4 websocket做一个特定于用户的主题订阅，我的应用程序不依赖于安全机制，握手失败，因为principal为空，我尝试扩展DefaultHandshakeHandler并覆盖determineUser受保护的方法，我需要填充主体对象和如何?如有任何帮助，不胜感激。

配置:

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/topic", "/user");
        config.setApplicationDestinationPrefixes("/app");
    }
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/hello").setHandshakeHandler(customHandshakeHandler()).withSockJS();
    }
    @Bean
    public CustomHandshakeHandler customHandshakeHandler() {
        return new CustomHandshakeHandler();
    }
}

CustomHandshakeHandler.java

public class CustomHandshakeHandler extends DefaultHandshakeHandler {
    @Override
    protected Principal determineUser(ServerHttpRequest request, WebSocketHandler wsHandler, 
            Map<String, Object> attributes) {
        return request.getPrincipal(); // return null here, how to populate principal???
    }
}

服务器端:

template.convertAndSendToUser(username, "/greetings", new Greeting("Hello World!"));

客户端:

function connect(username) {
    var socket = new SockJS('http://localhost:8081/websocket/hello');
    stompClient = Stomp.over(socket);
    stompClient.connect({}, function(frame) {
        setConnected(true);
        console.log('Connected: ' + frame);
        //stompClient.subscribe('/topic/greetings', function(greeting){
        stompClient.subscribe('/user/' + username + '/greetings', function(greeting){
            showGreeting(JSON.parse(greeting.body).content);
        });
    });
}

Answer 1

你在问一件事，但你发布的错误日志显示另一个问题:

. lang。javax.websocket.server. exception:ServerContainer的ServletContext属性。您是否运行在支持JSR-356的Servlet容器中?

所以你在一个支持JSR-356的servlet容器中运行吗?如果在Tomcat上运行，则至少需要Tomcat 7.0.47。对于其他servlet容器，您必须检查需要的版本。从Spring文档:

Spring框架提供了一个WebSocket API，旨在适应各种WebSocket引擎。例如，它运行在JSR-356运行时，如Tomcat (7.0.47+)， GlassFish(4.0+)和WildFly(8.0+)，但也可以适应其他WebSocket运行时，如Jetty(9.1+)本地WebSocket支持。
