dubbo-admin控制臺啟動報錯

本文是小編的第一篇：開啟java學習晉升之路，如遇大佬，還請多多指導

前言

在學習dubbo的時候需要監控消費者和生產者，所以需要安裝dubbo-admin：
小編是在github上下載最新的Dubbo Admin 0.3.0，遇到了問題，這里記錄一下

一、下載安裝dubbo-admin

網上有很多大佬的教程，這里不再贅述，小編看的教程是

二、遇到問題

三、解決辦法

如果有小伙伴不小看啰嗦的分析，直接看解決辦法，如果想看小編的心路歷程，請繼續看分析思路

四、思路分析

這個dubbo-admin是一個標準的spring-boot專案，直接開啟除錯

1、從報錯資訊看（從上往下）

根據Caused by: java.lang.IllegalStateException: zookeeper not connected at org.apache.dubbo.remoting.zookeeper.curator.CuratorZookeeperClient.(CuratorZookeeperClient.java:87)

2、解決

現在只需要在前面傳入的引數設定大一點超時時間，不用默認的超時時間就行，具體設定，見上解決辦法

3、分析為什么會超時默認時間

小編用的zookeeper是在，遠程的linux服務器上的（騰訊云），因為是學習用的，配置和延時都比較高，所以需要設定大一點

總結

這可能是最笨的辦法，但是小編學習springboot+dubbo的開篇問題解決，希望大佬能指導更好的辦法！學無止境，小伙伴們一起來挖坑吧！
