架构说明:

父工程:dubbo-spring-cloud

对外开放的普通maven工程:dubbo-spring-cloud-api

生产者/提供者:dubbo-spring-cloud-provider

消费者:dubbo-spring-cloud-consumer


第一步:创建一个父工程:dubbo-spring-cloud

1、pom文件信息如下:


        dubbo-spring-cloud-api
        dubbo-spring-cloud-consumer
        dubbo-spring-cloud-provider




        
            org.springframework.boot
            spring-boot-starter-actuator
        
        
            org.springframework
            spring-core
            5.3.6
        
        
            org.springframework.boot
            spring-boot-starter-web
        
        
            org.projectlombok
            lombok
            true
        
        
            org.springframework.boot
            spring-boot-starter-test
            test
        



        
            
                org.springframework.cloud
                spring-cloud-dependencies
                Finchley.SR1
                pom
                import
            
            
                org.springframework.boot
                spring-boot-dependencies
                2.1.11.RELEASE
                pom
                import
            
            
                com.alibaba.cloud
                spring-cloud-alibaba-dependencies
                2.1.1.RELEASE
                pom
                import
            
        

第二步:创建一个maven工程:dubbo-spring-cloud-api

1、编写一个对外开放的接口类:IHelloService,代码如下

public interface IHelloService {
    String sayHello(String name);
}

2、然后使用maven命令:mvn clean install -DskipTests在本地构建一下,方便下游服务调用

第三步:创建一个springboot提供者服务:dubbo-spring-cloud-provider

1、pom文件信息如下:


        
            org.springframework.boot
            spring-boot-starter
        
        
            com.alibaba.cloud
            spring-cloud-starter-dubbo
        
        
            org.springframework.cloud
            spring-cloud-starter-zookeeper-discovery
        
        
            com.cb
            dubbo-spring-cloud-api
            0.0.1-SNAPSHOT
        
        
            org.apache.curator
            curator-framework
            2.8.0
        
        
            org.apache.curator
            curator-recipes
            2.8.0
        
        
            org.apache.curator
            curator-client
            2.13.0
        

2、实现api接口,代码如下:

@Service    //服务注册
@org.springframework.stereotype.Service //spring注入
public class HelloServiceImpl implements IHelloService {
    public String sayHello(String name) {
        return name;
    }
}

3、配置文件如下:

#dubbo相关配置
dubbo.protocol.name=dubbo
dubbo.protocol.port=20880
dubbo.registry.address=zookeeper://192.168.1.107:2181
dubbo.scan.base-packages=com.cb.dubbospringcloudprovider.impl


#cloud相关配置
spring.cloud.zookeeper.connect-string=192.168.1.107:2181
spring.cloud.zookeeper.discovery.instance-host=192.168.1.107
spring.cloud.zookeeper.discovery.instance-port=8088
spring.cloud.zookeeper.discovery.register=true


#spring相关配置
server.port=8088
spring.application.name=dubbo-spring-cloud-provider

4、启动类如下:

@SpringBootApplication
@EnableDubbo
public class DubboSpringCloudProviderApplication {

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

}

5、然后启动该类,启动成功之后,打开zk可视化工具,查看注册信息,截图如下:

说明提供者已被注册,结构也是正确的

第四步:创建一个springboot消费者服务:dubbo-spring-cloud-consumer

1、pom信息与提供者的pom相同即可

2、创建一个controller,远程调用提供者和api接口类,实现远程调用

@RestController
public class HelloController {
    @Reference(retries = 0,check = false)
    private IHelloService iHelloService;

    @GetMapping("/say")
    public String sayHello(){
        return iHelloService.sayHello("hello world");
    }
}

3、启动类如下

@SpringBootApplication
@EnableDiscoveryClient
public class DubboSpringCloudConsumerApplication {

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

}

4、配置文件如下:

#指定要远程调用的注册服务名,不声明的话默认是扫描全部服务
dubbo.cloud.subscribed-services=dubbo-spring-cloud-provider
#注册服务名
spring.application.name=dubbo-spring-cloud-consumer
#是否注册
spring.cloud.zookeeper.discovery.register=true
#注册中心ip:port字符串
spring.cloud.zookeeper.connect-string=192.168.1.107:2181
#扫描需要注册的类包路径
dubbo.scan.base-packages=com.cb.dubbospringcloudconsumer
server.port=8070
#注册节点
dubbo.protocol.name=dubbo
#dubbo服务端口,默认是20880
dubbo.protocol.port=20881
#zk链接地址
dubbo.registry.address=zookeeper://192.168.179.114:2181

5、然后启动该类,启动成功之后,打开zk可视化工具,查看注册信息,截图如下:

说明消费者注册成功

第五步:远程调用消费者的接口

1、访问 http://localhost:8070/say

返回:hello world

返回正确,集成到这里就结束啦!
