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
