我正在做一個用戶特定的主題訂閱使用春天4 websocket，我的應用程序不依賴於安全機制，握手失敗，因爲本金是null，我試圖擴展DefaultHandshakeHandler並覆蓋確定用戶受保護的方法，我是否需要填充主體對象，以及如何？任何幫助將不勝感激。春季websocket遇到「忽略消息，沒有可用的主要信息」錯誤
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???
}
}
服務器端：
template.convertAndSendToUser(username, "/greetings", new Greeting("Hello World!"));
客戶端：
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);
});
});
}
