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

    <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

　　接口实现类

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

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

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：

root

root

guest

guest

3.1、访问
