Springboot的websocket的客户端

 项目要求要做一个订阅第三方的websocket数据，然后就记录了一个小例子、

pom文件，引入依赖

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

websocket的配置 

package com.mp.core.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.server.standard.ServerEndpointExporter;

import javax.websocket.server.ServerEndpointConfig;

/**
 * @author lrx
 * @create 2020-08-14 19:33
 * websocket配置类
 */
@Configuration
public class WebSocketConfig{

    @Bean
    public ServerEndpointExporter serverEndpointExporter() {
        return new ServerEndpointExporter();
    }

}

package com.mp.core.websocket;

import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;
import javax.websocket.*;
import java.io.IOException;
import java.net.URI;

/**

 */
@Slf4j
@Component
@ClientEndpoint
public class CameraEventSocketClient {
    private String serverUrl="接收地址";
    private Session session;

    @PostConstruct
    void init() {
        try {
            WebSocketContainer container = ContainerProvider.getWebSocketContainer();
            URI uri = URI.create(serverUrl);
            session = container.connectToServer(CameraEventSocketClient.class, uri);
        } catch (DeploymentException | IOException e) {
            e.printStackTrace();
        }
    }

    /**
     * 打开连接
     * @param session
     */
    @OnOpen
    public void onOpen(Session session) {
        log.info("打开");
        this.session = session;
    }

    /**
     * 接收消息
     * @param text
     */
    @OnMessage
    public void onMessage(String text) {
        log.info("接收消息："+text);

    }

    /**
     * 异常处理
     * @param throwable
     */
    @OnError
    public void onError(Throwable throwable) {
        throwable.printStackTrace();
    }

    /**
     * 关闭连接
     */
    @OnClose
    public void onClosing() throws IOException {
        log.info("关闭");
        session.close();
    }

    /**
     * 主动发送消息
     */
    public void send(String message) {
        this.session.getAsyncRemote().sendText(message);
    }
    public void close() throws IOException{
        if(this.session.isOpen()){
            this.session.close();
        }
    }
}

结果：
