原因是开启了监控

关闭了之后，请求都可以成功了
集群的话处理跟单机的有什么区别？
从配置入手，主要是Bootstrap中的配置
soul:
sync:
websocket :
urls: ws://localhost:9095/websocket,ws://localhost:9096/websocket
配置文件：WebsocketSyncDataConfiguration
同步服务：WebsocketSyncDataService
Bootstrap服务中会获取urls，遍历连接admin服务进行连接
/**
* Instantiates a new Websocket sync cache.
*
* @param websocketConfig the websocket config
* @param pluginDataSubscriber the plugin data subscriber
* @param metaDataSubscribers the meta data subscribers
* @param authDataSubscribers the auth data subscribers
*/
public WebsocketSyncDataService(final WebsocketConfig websocketConfig,
final PluginDataSubscriber pluginDataSubscriber,
final List metaDataSubscribers,
final List authDataSubscribers) {
// 获取注册的url列表
String[] urls = StringUtils.split(websocketConfig.getUrls(), ",");
// 线程池
executor = new ScheduledThreadPoolExecutor(urls.length, SoulThreadFactory.create("websocket-connect", true));
// 新增插件订阅Websocket订阅者信息
for (String url : urls) {
try {
clients.add(new SoulWebsocketClient(new URI(url), Objects.requireNonNull(pluginDataSubscriber), metaDataSubscribers, authDataSubscribers));
} catch (URISyntaxException e) {
log.error("websocket url({}) is error", url, e);
}
}
try {
for (WebSocketClient client : clients) {
// Websocket连接，30s
boolean success = client.connectBlocking(3000, TimeUnit.MILLISECONDS);
if (success) {
log.info("websocket connection is successful.....");
} else {
log.error("websocket connection is error.....");
}
// 定时连接同步配置信息
executor.scheduleAtFixedRate(() -> {
try {
if (client.isClosed()) {
boolean reconnectSuccess = client.reconnectBlocking();
if (reconnectSuccess) {
log.info("websocket reconnect is successful.....");
} else {
log.error("websocket reconnection is error.....");
}
}
} catch (InterruptedException e) {
log.error("websocket connect is error :{}", e.getMessage());
}
}, 10, 30, TimeUnit.SECONDS);
}
/* client.setProxy(new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxyaddress", 80)));*/
} catch (InterruptedException e) {
log.info("websocket connection...exception....", e);
}
}
admin中就可以使用已经连接的WebSocket通道进行发送变动的配置信息
DataSyncConfiguration中WebsocketListener的WebsocketDataChangedListener
集群的话处理跟单机就是比单机的时候多推了几个配置信息，然后Bootstrap就根据配置信息进行代理就可以了。
