廢話不多說 開整

新建dubbo-parent  父工程 加入以下jar包

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.2.RELEASE</version>
</parent>
<properties>
    <project.build.sourceEncoding>
 
UTF-8</project.build.sourceEncoding>
    <java.version>1.8</java.version>
    <dubbo-spring-boot>1.0.0</dubbo-spring-boot>
</properties>
<modules>
    <module>dubbo-consumer</module>
    <module>dubbo-provider</module>
    <module>dubbo-api</
 
module>
</modules>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId
 
>
        <artifactId>spring-boot-starter-test</artifactId>
    </dependency>
    <!-- Spring Boot Dubbo 依賴 -->
<dependency>
        <groupId>io.dubbo.springboot</groupId>
        <artifactId>spring-boot-starter-dubbo</artifactId>
        <version>${dubbo-spring-boot}</version>
    </dependency>
    <!-- Junit -->
<dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
    </dependency>
</dependencies>

新建三個Module

dubbo-api  

dubbo-provider

dubbo-consumer

在dubbo-provider 和dubbo-consumer下引入dubbo-api.jar  

<dependency>
    <groupId>com.chengzhi</groupId>
    <artifactId>dubbo-api</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>

<dependency>
    <groupId>com.chengzhi</groupId>
    <artifactId>dubbo-api</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>

在dubbo下建立要釋出的介面

public interface DubboService {
    public void sayHello(String name);
}

在dubbo-provider 建立啟動類

@SpringBootApplication
public class ProviderApplication {
    public static void main(String[] args){
        SpringApplication.run(ProviderApplication.class,args);
    }
}

import com.alibaba.dubbo.config.annotation.Service;（引包）

@Service(version = "1.0.0")
public class DubboServiceImpl implements DubboService{
    @Override
public void sayHello(String name) {
        System.out.println(name);       
    }
}

resource下新建application.properties

server.port=7001
#應用名稱
spring.dubbo.application.name=dubbo-provider
#註冊中心地址
spring.dubbo.registry.address=zookeeper://192.168.50.130:4180
#暴露服務方式
spring.dubbo.protocol.name=dubbo
#暴露服務埠
spring.dubbo.protocol.port=20880

#暴露服務包
spring.dubbo.scan=com.chengzhi.web.servive.impl

在dubbo-consumer中

@SpringBootApplication
public class ConsumerApplication {
    public static void main(String[] args){
        SpringApplication.run(ConsumerApplication.class,args);
    }
}

@RestController
@RequestMapping("/dubbo")
public class DubboController {

//    @Resource
@Reference(version = "1.0.0")
    DubboService dubboService;

    @RequestMapping("sayHello")
    public void sayHello() {      
        dubboService.sayHello("consumer 請求服務");
    }


}

@RestController
@RequestMapping("/dubbo")
public class DubboController {

//    @Resource
@Reference(version = "1.0.0")
    DubboService dubboService;

    @RequestMapping("sayHello")
    public void sayHello() {
        System.out.println("dubbo開始呼叫");
        dubboService.sayHello("consumer 請求服務");
    }


}

@RestController
@RequestMapping("/dubbo")
public class DubboController {

//    @Resource
@Reference(version = "1.0.0")
    DubboService dubboService;

    @RequestMapping("sayHello")
    public void sayHello() {
        System.out.println("dubbo開始呼叫");
        dubboService.sayHello("consumer 請求服務");
    }


}

server.port=7002
#應用名稱
spring.dubbo.application.name=dubbo-consumer
#註冊中心地址
spring.dubbo.registry.address=zookeeper://192.168.50.130:4180

#路徑
spring.dubbo.scan=com.chengzhi.web

zookeeper需要自己搭建

分別啟動dubbo-provider和dubbo-consumer

控制檯會列印連線zookeeper資訊

再看zookeeper

[zk: 127.0.0.1:4180(CONNECTED) 14] ls /
[dubbo, zookeeper]
[zk: 127.0.0.1:4180(CONNECTED) 15] ls /dubbo
[com.chengzhi.web.service.DubboService]
[zk: 127.0.0.1:4180(CONNECTED) 16] ls /dubbo/com.chengzhi.web.service.DubboService/consumers
[consumer%3A%2F%2F192.168.50.1%2Fcom.chengzhi.web.service.DubboService%3Fapplication%3Ddubbo-consumer%26category%3Dconsumers%26check%3Dfalse%26dubbo%3D2.5.3%26interface%3Dcom.chengzhi.web.service.DubboService%26methods%3DsayHello%26pid%3D15996%26revision%3D1.0-SNAPSHOT%26side%3Dconsumer%26timestamp%3D1515232367366%26version%3D1.0.0]
[zk: 127.0.0.1:4180(CONNECTED) 17] ls /dubbo/com.chengzhi.web.service.DubboService/providers
[dubbo%3A%2F%2F192.168.50.1%3A20880%2Fcom.chengzhi.web.service.DubboService%3Fanyhost%3Dtrue%26application%3Ddubbo-provider%26dubbo%3D2.5.3%26interface%3Dcom.chengzhi.web.service.DubboService%26methods%3DsayHello%26pid%3D14820%26revision%3D1.0-SNAPSHOT%26side%3Dprovider%26timestamp%3D1515233416711%26version%3D1.0.0]

可以看到我們已經把服務發不到zookeeper上面了

效果如下
