springboot整合最新版dubbo以及dubbo-admin的安装

1、安装前准备

  因为dubbo被阿里捐献给了apache,此次安装admin时,参考网上的资料,地址仍是停留在以前的连接,踩了很多坑,这里记录下。java

  dubbo-admin下载地址:mysql

  地址一:https://github.com/apache/incubator-dubbo/releases git

    该地址2.6版本以上的包中没有dubbo-admin ,2.5x版本的有github

  地址二:https://github.com/apache/incubator-dubbo-opsweb

    该地址中的dubbo-admin模块被单独拎出来了,springboot方式启动,能够直接运行main方法,或者使用 java -jar 方式启动,很方便,有github帐号的能够fork一下,推荐使用这个版本,本文介绍的就是该版本  。redis

2、dubbo-spring-boot-starter的使用

  github地址:https://github.com/alibaba/dubbo-spring-boot-starter 最新版本为2.0 ,本文也是使用的该版本。spring

2.一、添加依赖

<dependency>
     <groupId>com.alibaba.spring.boot</groupId>
     <artifactId>dubbo-spring-boot-starter</artifactId>
     <version> 2.0 . 0 </version>
</dependency>

2.二、新建接口模块

3、dubbo-admin的启动

下载地址二的包,直接在idea中打开,结构以下:

install完成以后,直接右键DubboAdminApplication  Run 

修改配置文件,位置在 dubbo-admin /src/main/resource下面

根据本身的须要修改,包括dubbo-admin用户名密码,固然zk的配置也是少不了的,具体怎么安装zk,启动以及配置,这里就很少说了,

默认的的用户名和密码为:

1

root

guest

3.一、访问

localhost:7001

 首页

 service

 provider

  consumer
