    springboot整合最新版dubbo以及dubbo-admin的安装

     

    一、安装前准备

    　　由于dubbo被阿里捐献给了apache,这次安装admin时，参考网上的资料，地址还是停留在之前的链接，踩了不少坑，这里记录下。

    　　dubbo-admin下载地址：

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

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

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

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

    二、dubbo-spring-boot-starter的使用

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

    2.1、添加依赖

        <groupId>com.alibaba.spring.boot</groupId>
        <artifactId>dubbo-spring-boot-starter</artifactId>
        <version>2.0.0</version>
    </dependency>

    2.2、新建接口模块

    public interface RemoteUserService {
     
     
        String sayHello(String name);
     
     
    }

     **/
    @RestController
    public class RemoteUserController {
     
        //timeout 可以不指定，但是version一定要指定 不然会找不到服务 直连需要加url="dubbo://localhost:20880"
        @Reference(version = "1.0.0")
        private RemoteUserService remoteUserService;
     
     
        @RequestMapping(value="/dubbo/say/{name}")
        public String sayHello(@PathVariable("name") String name){
     
            String result=remoteUserService.sayHello(name);
            return result;
        }
     
     
    }

    三、dubbo-admin的启动

    下载地址二的包，直接在idea中打开，结构如下：

    install完成之后，直接右键DubboAdminApplication  Run 

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

    server.port=7001
    spring.velocity.cache=false
    spring.velocity.charset=UTF-8
    spring.velocity.layout-url=/templates/default.vm
    spring.messages.fallback-to-system-locale=false
    spring.messages.basename=i18n/message
    spring.root.password=root
    spring.guest.password=guest
     
    dubbo.registry.address=zookeeper://127.0.0.1:2181

    根据自己的需要修改，包括dubbo-admin用户名密码，当然zk的配置也是少不了的，具体怎么安装zk，启动以及配置，这里就不多说了，

    默认的的用户名和密码为：

    1
    2
    3
    4
    5
    root
    root
     
    guest
    guest

    3.1、访问

    localhost:7001

    　首页

    　service

    　provider

      consumer

    完整代码已上传github 欢迎fork  传送门

    沉得住气，沉淀自己。
