我的WEB專案中使用curator作為Zookeeper的客戶端,設定重連策略如下:
@Autowired
public ZookeeperUtil(EnvironmentUtil environmentUtil){
this.environmentUtil = environmentUtil;
RetryPolicy retryPolicy = new ExponentialBackoffRetry(1000,3);
zookeeperClient = CuratorFrameworkFactory.newClient("127.0.0.1:2181",retryPolicy);
zookeeperClient.start();
}
當127.0.0.1:2181這臺機器的Zookeeper服務不啟動時,zookeeperClient.start()后就會無限重連,重連策略沒有生效,請問是什么原因呢?
例外如下,不止這一個,只要zookeeper服務不啟動,就會一直不停的重連下去:
