效果演示鸿蒙开源组件——对STOMP协议支持长连接 收发消息-开源基础软件社区

安装教程

1.在项目根目录下的build.gradle文件中,

allprojects {
   repositories {
       maven {
           url 'https://s01.oss.sonatype.org/content/repositories/releases/'
       }
   }
}

2.在entry模块的build.gradle文件中,

dependencies {
     implementation('com.gitee.chinasoft_ohos:StompProtocolOhos:1.0.1')
   ......  
}

在sdk6,DevEco Studio 2.2 Beta1下项目可直接运行 如无法运行,删除项目.gradle,.idea,build,gradle,build.gradle文件, 并依据自己的版本创建新项目,将新项目的对应文件复制到根目录下

使用说明

  1. 后端示例:

WebSocketConfig.groovy

@Configuration
@EnableWebSocket

@EnableWebSocketMessageBroker

class WebSocketConfig implements WebSocketMessageBrokerConfigurer {

    @Override
    void configureMessageBroker(MessageBrokerRegistry config) {

        long[] heartbeat = [ 30000, 30000 ];
        config.enableSimpleBroker("/topic", "/queue", "/exchange")
            .setTaskScheduler(new DefaultManagedTaskScheduler()) // enable heartbeats
            .setHeartbeatValue(heartbeat); // enable heartbeats
//        config.enableStompBrokerRelay("/topic", "/queue", "/exchange"); // Uncomment for external message broker (ActiveMQ, RabbitMQ)
        config.setApplicationDestinationPrefixes("/topic", "/queue"); // prefix in client queries
        config.setUserDestinationPrefix("/user");
    }

    @Override
    void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/example-endpoint").setAllowedOrigins("*").withSockJS()
    }

    @Override
    void configureWebSocketTransport(WebSocketTransportRegistration registration) {
        registration.setMessageSizeLimit(8 * 1024);
    }
}

SocketController.groovy

@Slf4j
@RestController
class SocketController {

    @Autowired
    SocketService socketService

    @MessageMapping('/hello-msg-mapping')
    @SendTo('/topic/greetings')
    EchoModel echoMessageMapping(String message) {
        log.debug("React to hello-msg-mapping")
        return new EchoModel(message.trim())
    }

    @RequestMapping(value = '/hello-convert-and-send', method = RequestMethod.POST)
    void echoConvertAndSend(@RequestParam('msg') String message) {
        socketService.echoMessage(message)
    }
}
  1. 示例用法:

基本用法

 private StompClient mStompClient;

 // ...
 
 mStompClient = Stomp.over(Stomp.ConnectionProvider.OKHTTP, "ws://" + OhOS_EMULATOR_LOCALHOST + ":" + RestClient.SERVER_PORT + "/example-endpoint/websocket");
 mStompClient.connect();
  
	mStompClient.topic("/topic/greetings")
	                .subscribeOn(Schedulers.io())
	                .observeOn(HarmonySchedulers.mainThread())
	                .subscribe(topicMessage -> {
	                    debug("Received " + topicMessage.getPayload());
	                    addItem(mGson.fromJson(topicMessage.getPayload(), EchoModel.class));
	                }, throwable -> {
	                    debug("Error on subscribe topic" + throwable);
	                });
  
 // ...

 mStompClient.disconnect();

. 订阅生命周期连接:

lifecycleDisposable = connectionProvider.lifecycle()
                	.subscribe(lifecycleEvent -> {
                    switch (lifecycleEvent.getType()) {
                        case OPENED:
                          HiLog.error(LABEL, "Socket opened");
                            break;

                        case CLOSED:
                            HiLog.error(LABEL, "Socket closed");
                            disconnect();
                            break;

                        case ERROR:
                            HiLog.error(LABEL, "Socket closed with error");
                            lifecyclePublishSubject.onNext(lifecycleEvent);
                            break;
                        default:
                            break;
                    }
                });
