我为spring-web app添加了基于自定义令牌的身份验证,并为spring websocket扩展了如下所示
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/topic", "/queue");
config.setApplicationDestinationPrefixes("/app");
config.setUserDestinationPrefix("/user");
}
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/gs-guide-websocket").setAllowedOrigins("*").withSockJS();
}
@Override
public void configureClientInboundChannel(ChannelRegistration registration) {
registration.setInterceptors(new ChannelInterceptorAdapter() {
@Override
public Message<?> preSend(Message<?> message, MessageChannel channel) {
StompHeaderAccessor accessor =
MessageHeaderAccessor.getAccessor(message, StompHeaderAccessor.class);
if (StompCommand.CONNECT.equals(accessor.getCommand())) {
String jwtToken = accessor.getFirstNativeHeader("Auth-Token");
if (!StringUtils.isEmpty(jwtToken)) {
Authentication auth = tokenService.retrieveUserAuthToken(jwtToken);
SecurityContextHolder.getContext().setAuthentication(auth);
accessor.setUser(auth);
//for Auth-Token '12345token' the user name is 'user1' as auth.getName() returns 'user1'
}
}
return message;
}
});
}
}
连接到套接字的客户端代码是
var socket = new SockJS('http://localhost:8080/gs-guide-websocket');
stompClient = Stomp.over(socket);
stompClient.connect({'Auth-Token': '12345token'}, function (frame) {
stompClient.subscribe('/user/queue/greetings', function (greeting) {
alert(greeting.body);
});
});
从我的控制器我发送消息
messagingTemplate.convertAndSendToUser("user1", "/queue/greetings", "Hi User1");
对于身份验证令牌12345token
,用户名为user1
。但是当我向user1
发送消息时,它未在客户端收到。我有什么遗漏吗?

在您的Websocket控制器中,您应该执行以下操作:
@Controller
public class GreetingController {
@Autowired
private SimpMessagingTemplate messagingTemplate;
@MessageMapping("/hello")
public void greeting(Principal principal, HelloMessage message) throws Exception {
Greeting greeting = new Greeting();
greeting.setContent("Hello!");
messagingTemplate.convertAndSendToUser(message.getToUser(), "/queue/reply", greeting);
}
}
在客户端,您的用户应订阅topic / user / queue / reply。
您还必须添加一些目的地前缀:
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/topic", "/queue" ,"/user");
config.setApplicationDestinationPrefixes("/app");
config.setUserDestinationPrefix("/user");
}
/*...*/
}
当您的服务器在/ app / hello队列上收到消息时,它应该向您的dto中的用户发送消息。用户必须等于用户的主体。
我认为代码中唯一的问题是您的“/ user”不在您的目标前缀中。您的问候语消息被阻止,因为您将它们发送到以/ user开头的队列中,并且此前缀未注册。

希望它有效!

在我之前的项目中,我向一个特定用户发送了消息;详细说明我写了以下内容:
客户端:
function stompConnect(notificationTmpl)
{
var socket = new SockJS('/comm-svr');
stompClient = Stomp.over(socket);
var theUserId
stompClient.connect({userId:theUserId}, function (frame) {
debug('Connected: ' + frame);
stompClient.subscribe('/topic/connect/'+theUserId, function (data) {
//Handle data
}
});
}
服务器端
Spring websocket listener:
@Component
public class WebSocketSessionListener
{
private static final Logger logger = LoggerFactory.getLogger(WebSocketSessionListener.class.getName());
private List<String> connectedClientId = new ArrayList<String>();
@EventListener
public void connectionEstablished(SessionConnectedEvent sce)
{
MessageHeaders msgHeaders = sce.getMessage().getHeaders();
Principal princ = (Principal) msgHeaders.get("simpUser");
StompHeaderAccessor sha = StompHeaderAccessor.wrap(sce.getMessage());
List<String> nativeHeaders = sha.getNativeHeader("userId");
if( nativeHeaders != null )
{
String userId = nativeHeaders.get(0);
connectedClientId.add(userId);
if( logger.isDebugEnabled() )
{
logger.debug("Connessione websocket stabilita. ID Utente "+userId);
}
}
else
{
String userId = princ.getName();
connectedClientId.add(userId);
if( logger.isDebugEnabled() )
{
logger.debug("Connessione websocket stabilita. ID Utente "+userId);
}
}
}
@EventListener
public void webSockectDisconnect(SessionDisconnectEvent sde)
{
MessageHeaders msgHeaders = sde.getMessage().getHeaders();
Principal princ = (Principal) msgHeaders.get("simpUser");
StompHeaderAccessor sha = StompHeaderAccessor.wrap(sde.getMessage());
List<String> nativeHeaders = sha.getNativeHeader("userId");
if( nativeHeaders != null )
{
String userId = nativeHeaders.get(0);
connectedClientId.remove(userId);
if( logger.isDebugEnabled() )
{
logger.debug("Connessione websocket stabilita. ID Utente "+userId);
}
}
else
{
String userId = princ.getName();
connectedClientId.remove(userId);
if( logger.isDebugEnabled() )
{
logger.debug("Connessione websocket stabilita. ID Utente "+userId);
}
}
}
public List<String> getConnectedClientId()
{
return connectedClientId;
}
public void setConnectedClientId(List<String> connectedClientId)
{
this.connectedClientId = connectedClientId;
}
}
Spring websocket邮件发件人:
@Autowired
private SimpMessagingTemplate msgTmp;
private void propagateDvcMsg( WebDeviceStatusInfo device )
{
String msg = "";
String userId =((Principal)SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getName()
msgTmp.convertAndSend("/topic/connect"+userId, msg);
}
我希望它有用
