  • Intelligent load balancing
  • Automatic service registration and discovery
  • High extensibility
  • Runtime traffic routing
  • Visualized service governance

Getting started

The following code snippet comes from Dubbo Samples. You may clone the sample project and step into dubbo-samples-api sub directory before read on.

# git clone https://github.com/dubbo/dubbo-samples.git
# cd dubbo-samples/dubbo-samples-api

There's a README file under dubbo-samples-api directory. Read it and try this sample out by following the instructions.

Maven dependency

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>dubbo</artifactId>
    <version>2.6.4</version>
</dependency>

Define service interfaces

package org.apache.dubbo.demo.api;

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

See api/GreetingService.java on GitHub.

Implement service interface for the provider

package org.apache.dubbo.demo.provider;
 
import org.apache.dubbo.demo.GreetingService;
 
public class GreetingServiceImpl implements GreetingService {
    public String sayHello(String name) {
        return "Hello " + name;
    }
}

See provider/GreetingServiceImpl.java on GitHub.

Start service provider

package org.apache.dubbo.demo.provider;

import com.alibaba.dubbo.config.ApplicationConfig;
import com.alibaba.dubbo.config.RegistryConfig;
import com.alibaba.dubbo.config.ServiceConfig;
import org.apache.dubbo.demo.GreetingService;

import java.io.IOException;
 
public class Application {

    public static void main(String[] args) throws IOException {
        ServiceConfig<GreetingService> serviceConfig = new ServiceConfig<GreetingService>();
        serviceConfig.setApplication(new ApplicationConfig("first-dubbo-provider"));
        serviceConfig.setRegistry(new RegistryConfig("multicast://224.5.6.7:1234"));
        serviceConfig.setInterface(GreetingService.class);
        serviceConfig.setRef(new GreetingServiceImpl());
        serviceConfig.export();
        System.in.read();
    }
}

See provider/Application.java on GitHub.

Build and run the provider

# mvn clean package
# mvn -Djava.net.preferIPv4Stack=true -Dexec.mainClass=org.apache.dubbo.demo.provider.Application exec:java

Call remote service in consumer

package org.apache.dubbo.demo.consumer;

import com.alibaba.dubbo.config.ApplicationConfig;
import com.alibaba.dubbo.config.ReferenceConfig;
import com.alibaba.dubbo.config.RegistryConfig;
import org.apache.dubbo.demo.GreetingService;

public class Application {
    public static void main(String[] args) {
        ReferenceConfig<GreetingService> referenceConfig = new ReferenceConfig<GreetingService>();
        referenceConfig.setApplication(new ApplicationConfig("first-dubbo-consumer"));
        referenceConfig.setRegistry(new RegistryConfig("multicast://224.5.6.7:1234"));
        referenceConfig.setInterface(GreetingService.class);
        GreetingService greetingService = referenceConfig.get();
        System.out.println(greetingService.sayHello("world"));
    }
}

Build and run the consumer

# mvn clean package
# mvn -Djava.net.preferIPv4Stack=true -Dexec.mainClass=org.apache.dubbo.demo.consumer.Application exec:java

The consumer will print out Hello world on the screen.

See consumer/Application.java on GitHub.
