springboot整合最新版dubbo以及dubbo-admin的安装

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

1 2 3 4 5

<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

1 2 3 4 5 6 7 8 9

package com.dc.sb.service;   public interface RemoteUserService {         String sayHello(String name);     }

2.3、新建provider模块

　　目录结构

　　接口实现类

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

package com.dc.sb.dubbo.provider.service.user;   import com.alibaba.dubbo.config.annotation.Service; import com.dc.sb.service.RemoteUserService; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.stereotype.Component;   /**  * dubbo 服务service  *  * @author DUCHONG  * @since 2018-07-03 18:29  **/ @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

1 2 3 4 5 6

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

#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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

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

沉得住气，沉淀自己。
