有一个项目，比如聊天室。
1，在我的测试html5页面（使用sockjs stomp.js）为什么在连接成功约3分钟后连接丢失了？
2，我应该实施与心跳相关的任何代码吗？
3，Android使用 StomprotocolAndroid （https://github.com/NaikSoftware/StompProtocolAndroid）和iOS使用 WebsocketStompKit （https://github.com/mykoma/WebsocketStompKit）也会在几分钟后断开连接。
4，另一个项目，使用类似的代码，但服务器端将“h”发送给客户端 并且html5页面什么都不做，它仍然可以保持连接？

服务器端
配置代码：
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
public void registerStompEndpoints(
StompEndpointRegistry stompEndpointRegistry) {
stompEndpointRegistry.addEndpoint("/hello").setAllowedOrigins("*")
.withSockJS();
}
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/topic", "/user");
registry.setApplicationDestinationPrefixes("/app");
registry.setUserDestinationPrefix("/user");
}
}
控制器代码：
/***/
@RestController
public class GreetingController {
@Autowired
private SimpMessageSendingOperations simpMessageSendingOperations;
@MessageMapping("/hello")
@SendTo("/topic/greetings")
public Greeting greeting(@Header("atytopic") String topic, @Headers Map<String, Object> headers) {
System.out.println("connected successfully....");
System.out.println(topic);
System.out.println(headers);
return new Greeting("return from /topic/greetings");
}
@MessageMapping("/message")
@SendToUser("/message")
public Greeting handleSubscribe() {
System.out.println("this is the @SubscribeMapping('/marco')");
return new Greeting("I am a msg from SubscribeMapping('/macro').");
}
@RequestMapping(path = "/send", method = RequestMethod.GET)
public Greeting send() {
simpMessageSendingOperations.convertAndSendToUser("1", "/message", new Greeting("I am a msg from SubscribeMapping('/macro')."));
return new Greeting("I am a msg from SubscribeMapping('/macro').");
