Question

我正在开发一个Spring Boot应用程序，并通过套接字io服务器实现与客户端进行通信。我的意图是在特定功能中从服务器向客户端发送一个推送通知。我如何使其成为可能。我需要在单独的服务类中触发send事件。

Socket IO实现类

@Configuration
public class Socket {
    @Value("${socket.io.ip}")
    private String hostIP;

    @Value("${socket.io.port}")
    private int hostPort;

    @Bean
    public void setupSocketServer() {
        Configuration config = new Configuration();
        config.setHostname(hostIP);
        config.setPort(hostPort);
        SocketIOServer socketServer = new SocketIOServer(config);
        socketServer.addEventListener("chat", ChatObject.class, new DataListener<ChatObject>() {
            @Override
            public void onData(final SocketIOClient client, ChatObject data, final AckRequest ackRequest) {

                // check is ack requested by client,
                // but it's not required check
                if (ackRequest.isAckRequested()) {
                    // send ack response with data to client
                    ackRequest.sendAckData("client message was delivered to server!", "yeah!");
                }


                // send message back to client with ack callback WITH data
                ChatObject ackChatObjectData = new ChatObject(data.getUserName(), "message with ack data");
                client.sendEvent("chatResponse1", new AckCallback<String>(String.class) {
                    @Override
                    public void onSuccess(String result) {
                        System.out.println("ack from client: " + client.getSessionId() + " data: " + result);
                    }
                }, ackChatObjectData);
            }
        });

        socketServer.start();
    }
}

服务等级

class userService{
 void sendnotification(msg){
 // need to  call sendEvent function here
}

}

我通过使用套接字客户端的UUID实现了它。使用UUID创建了套接字客户端，该套接字客户端在将新客户端连接到服务器时被保存。并在需要的地方重复使用。

SocketIOClient client = socketServer.getClient(uuid);

在Java中使用Socket IO发送推送通知
