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
<dependency>
<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
目录结构
接口类
package com.dc.sb.service;
public interface RemoteUserService {
String sayHello(String name);
}
2.3、新建provider模块
目录结构

@Component
@Service(version = "1.0.0",timeout = 10000,interfaceClass = RemoteUserService.class)
public class RemoteUserServiceImpl implements RemoteUserService {
private static final Logger logger = LoggerFactory.getLogger(RemoteUserServiceImpl.class);
@Override
public String sayHello(String name) {
return "Hello "+name;
}
}
配置文件
server.port=8081 server.context-path=/ spring.application.name=dubbo-spring-boot-starter spring.dubbo.server=true spring.dubbo.registry=zookeeper://127.0.0.1:2181
启动类
package com.dc.sb.dubbo.provider;
import com.alibaba.dubbo.spring.boot.annotation.EnableDubboConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@EnableDubboConfiguration
public class SbDubboProviderApplication {
public static void main(String[] args) {
SpringApplication.run(SbDubboProviderApplication.class, args);
}
}
2.4、 消费者模块
目录结构
启动类
package com.dc.sb.web;
import com.alibaba.dubbo.spring.boot.annotation.EnableDubboConfiguration;
import com.dc.sb.config.DruidProperties;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication
@EnableConfigurationProperties({DruidProperties.class})
@MapperScan(basePackages = "com.dc.sb.dao")
@ComponentScan("com.dc.sb.*")
@EnableDubboConfiguration
public class SbWebApplication {
public static void main(String[] args) {
SpringApplication.run(SbWebApplication.class, args);
}
}
配置文件
#server server.port=8080 server.context-path=/ #mybatis mybatis.type-aliases-package= com.dc.sb.dao.dataobject mybatis.mapper-locations= classpath*:META-INF/mybatis/mapper/*.xml #druid druid.initialSize= 5 druid.minIdle= 0 druid.maxActive= 20 druid.maxWait= 6000 druid.timeBetweenEvictionRunsMillis= 60000 druid.minEvictableIdleTimeMillis= 300000 druid.validationQuery= SELECT 1 FROM DUAL druid.testWhileIdle= false druid.testOnBorrow= false druid.testOnReturn= false druid.poolPreparedStatements= true druid.maxPoolPreparedStatementPerConnectionSize= 20 druid.filters= stat,log4j #mysql spring.datasource.driver-class-name= com.mysql.jdbc.Driver spring.datasource.url= jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8&autoReconnect=true&useSSL=false&allowMultiQueries=true spring.datasource.username= root spring.datasource.password=root #redis spring.redis.host=127.0.0.1 spring.redis.port=6379 spring.redis.password=redis #dubbo spring.application.name=dubbo-spring-boot-starter spring.dubbo.registry=zookeeper://127.0.0.1:2181
引用端
package com.dc.sb.web.controller.remote;
import com.alibaba.dubbo.config.annotation.Reference;
import com.dc.sb.service.RemoteUserService;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* dubbo消费者controller
* @author DUCHONG
* @since 2018-07-03 18:44
**/
@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

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：
root root guest guest
3.1、访问
