springboot整合最新版dubbo以及dubbo-admin的安裝

1、安裝前準備

　　因爲dubbo被阿里捐獻給了apache,此次安裝admin時，參考網上的資料，地址仍是停留在以前的連接，踩了很多坑，這裏記錄下。

　　dubbo-admin下載地址：

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

　　　　該地址2.6版本以上的包中沒有dubbo-admin ,2.5x版本的有

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

　　　　該地址中的dubbo-admin模塊被單獨拎出來了，springboot方式啓動，能夠直接運行main方法，或者使用 java -jar 方式啓動，很方便，有github帳號的能夠fork一下，推薦使用這個版本，本文介紹的就是該版本  。

2、dubbo-spring-boot-starter的使用

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

2.一、添加依賴

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

2.二、新建接口模塊

　　目錄結構

　　接口類

package com.dc.sb.service;

public interface RemoteUserService {


    String sayHello(String name);


}

2.三、新建provider模塊

　　目錄結構

　　接口實現類

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 服務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

　　啓動類

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);
	}
}

2.四、 消費者模塊

　　目錄結構

　　啓動類

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消費者controller
 * @author DUCHONG
 * @since 2018-07-03 18:44
 **/
@RestController
public class RemoteUserController {

    //timeout 能夠不指定，可是version必定要指定 否則會找不到服務 直連須要加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;
    }


}

3、dubbo-admin的啓動

下載地址二的包，直接在idea中打開，結構以下：

install完成以後，直接右鍵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

根據本身的須要修改，包括dubbo-admin用戶名密碼，固然zk的配置也是少不了的，具體怎麼安裝zk，啓動以及配置，這裏就很少說了，

默認的的用戶名和密碼爲：

root
root

guest
guest
