现在我可以使用它了，但是我真的不知道 ：
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/stomp").withSockJS();
}
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/queue", "/topic"); // <- added "/queue"
registry.setApplicationDestinationPrefixes("/app");
registry.setUserDestinationPrefix("/user");
}
}
@MessageMapping("/search")
@SendToUser // <- maps to "/user/queue/search"
public String search(@Payload String xxx) {
return "TEST1234";
}
stompClient.subscribe('/user/queue/search', function(data){
alert(data.body);
});

现在，日志中还有一行代码，表示正在
那是以前没有的。
如果有人可以解释为什么我需要/queue映射才能正常工作，这仍然会很好。
