JAVA 实现websocket作为客户端（自动断线重连）

因为很少有这样作为客户端的使用，但是遇上特殊需求还是要作为客户端使用，spring-boot-starter集成的无法实现客户端，直接上代码

pom引入，这里使用的spring boot 其他项目自行下载jar包库

/**
 * websocket 建立连接...

@Component
public class Client {
    private static final Logger logger = LoggerFactory.getLogger(Client.class);

	public static void createConnect() throws Exception{
        WebSocketClient client = new WebSocketClient(new URI(这里是你连接的websocket的地址)) {

            @Override
            public void onOpen(ServerHandshake arg0) {
                logger.info("开始建立链接...");
            }

            @Override
            public void onMessage(String arg0) {
              logger.info("检测到服务器请求...arg0 : " + arg0);
            }

            @Override
            public void onError(Exception arg0) {
                arg0.printStackTrace();
                logger.info("客户端发生错误,即将关闭!");
            }

            @Override
            public void onClose(int arg0, String arg1, boolean arg2) {
                logger.info("客户端已关闭!");
                logger.info("开始尝试重新连接...");
                try {
                    Client.createConnect();
                } catch (Exception e) {
                    e.printStackTrace();
                    logger.info("重新连接失败,请检查网络!");
                }
            }
        };

		client.connect();
		//判断连接状态,
		while (client.getReadyState().equals(READYSTATE.OPEN)) {
			logger. info("成功建立链接!");
		}
	}
}

由于websocket是多例的无法直接注入可以使用：

public static UserService userService;
@Autowired
public void setService(UserService userService) {
    Client.userService = userService;
}

很简单直接调用

Client.createConnect();
或者@PostConstruct直接项目启动一起启动
