springboot websocketCLIENT

对于Spring Boot的WebSocket客户端，你可以按照以下步骤进行实现：
步骤一：首先，你需要在你的项目中添加相关的Maven依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-websocket</artifactId>
</dependency>

步骤二：接下来，你可以使用Java代码创建一个WebSocket客户端，并与服务器建立连接。以下是示例代码：

import org.springframework.web.socket.client.standard.StandardWebSocketClient;
import org.springframework.web.socket.messaging.WebSocketStompClient;

public class WebSocketClientExample {
    public static void main(String[] args) {
        String url = "ws://localhost:8080/your-websocket-endpoint";
        
        WebSocketStompClient stompClient = new WebSocketStompClient(new StandardWebSocketClient());
        
        // 连接到WebSocket服务器
        stompClient.connect(url, new WebSocketHandler());
        
        // 停留一段时间后关闭连接
        try {
            Thread.sleep(5000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        stompClient.stop();
    }
}

import org.springframework.messaging.simp.stomp.StompFrameHandler;
import org.springframework.messaging.simp.stomp.StompHeaders;
import org.springframework.messaging.simp.stomp.StompSession;
import org.springframework.messaging.simp.stomp.StompSessionHandlerAdapter;
import org.springframework.web.socket.TextMessage;
import org.springframework.web.socket.WebSocketSession;

public class WebSocketHandler extends StompSessionHandlerAdapter {
    @Override
    public void afterConnected(StompSession session, StompHeaders connectedHeaders) {
        session.subscribe("/topic/your-topic", new StompFrameHandler() {
            @Override
            public Type getPayloadType(StompHeaders headers) {
                return String.class;
            }
            
            @Override
            public void handleFrame(StompHeaders headers, Object payload) {
                String message = (String) payload;
                System.out.println("Received message: " + message);
            }
        });
        
        String message = "Hello, server!";
        session.send("/app/your-endpoint", message.getBytes());
    }
}

以上代码示例展示了如何创建一个Spring Boot的WebSocket客户端，并与服务器建立连接。你可以根据你的需求修改和扩展这个示例代码。
