springboot整合最新版dubbo以及dubbo-admin的安裝
一、安裝前准備
由於dubbo被阿里捐獻給了apache,這次安裝admin時，參考網上的資料，地址還是停留在之前的鏈接，踩了不少坑，這里記錄下。
dubbo-admin下載地址：
地址一：https://github.com/apache/incubator-dubbo/releases
該地址2.6版本以上的包中沒有dubbo-admin ,2.5x版本的有
地址二：https://github.com/apache/incubator-dubbo-ops
該地址中的dubbo-admin模塊被單獨拎出來了，springboot方式啟動，可以直接運行main方法，或者使用 java -jar 方式啟動，很方便，有github賬號的可以fork一下，推薦使用這個版本，本文介紹的就是該版本 。
二、dubbo-spring-boot-starter的使用
github地址：https://github.com/alibaba/dubbo-spring-boot-starter 最新版本為2.0 ，本文也是使用的該版本。
2.1、添加依賴

"name"
) String name){
String result=remoteUserService.sayHello(name);

三、dubbo-admin的啟動
下載地址二的包，直接在idea中打開，結構如下：
install完成之后，直接右鍵DubboAdminApplication Run
修改配置文件，位置在 dubbo-admin /src/main/resource下面

根據自己的需要修改，包括dubbo-admin用戶名密碼，當然zk的配置也是少不了的，具體怎么安裝zk，啟動以及配置，這里就不多說了，
