Apache Dubbo Project

Maven License

Apache Dubbo is a high-performance, Java-based open-source RPC framework. Please visit the official site for the quick start guide and documentation, as well as the wiki for news, FAQ, and release notes.

We are now collecting Dubbo user info to help us to improve Dubbo further. Kindly support us by providing your usage information on issue#1012: Wanted: who's using dubbo, thanks :)

Architecture

Features

Transparent interface based RPC
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 the dubbo-samples-api subdirectory before proceeding.

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

There's a README file under dubbo-samples-api directory. We recommend referencing the samples in that directory by following the below-mentioned instructions:

Maven dependency

<properties>
    <dubbo.version>2.7.10</dubbo.version>
</properties>

<dependencies>
    <dependency>
        <groupId>org.apache.dubbo</groupId>
        <artifactId>dubbo</artifactId>
        <version>${dubbo.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.dubbo</groupId>
        <artifactId>dubbo-dependencies-zookeeper</artifactId>
        <version>${dubbo.version}</version>
        <type>pom</type>
    </dependency>
</dependencies>

Define service interfaces

package org.apache.dubbo.samples.api;

public interface GreetingsService {
    String sayHi(String name);
}

See api/GreetingsService.java on GitHub.

Implement service interface for the provider

package org.apache.dubbo.samples.provider;

import org.apache.dubbo.samples.api.GreetingsService;

public class GreetingsServiceImpl implements GreetingsService {
    @Override
    public String sayHi(String name) {
        return "hi, " + name;
    }
}

See provider/GreetingsServiceImpl.java on GitHub.

Start service provider

package org.apache.dubbo.samples.provider;


import org.apache.dubbo.config.ApplicationConfig;
import org.apache.dubbo.config.RegistryConfig;
import org.apache.dubbo.config.ServiceConfig;
import org.apache.dubbo.samples.api.GreetingsService;

import java.util.concurrent.CountDownLatch;

public class Application {
    private static String zookeeperHost = System.getProperty("zookeeper.address", "127.0.0.1");

    public static void main(String[] args) throws Exception {
        ServiceConfig<GreetingsService> service = new ServiceConfig<>();
        service.setApplication(new ApplicationConfig("first-dubbo-provider"));
        service.setRegistry(new RegistryConfig("zookeeper://" + zookeeperHost + ":2181"));
        service.setInterface(GreetingsService.class);
        service.setRef(new GreetingsServiceImpl());
        service.export();

        System.out.println("dubbo service started");
        new CountDownLatch(1).await();
    }
}

See provider/Application.java on GitHub.

Build and run the provider

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

Call remote service in the consumer

package org.apache.dubbo.samples.client;


import org.apache.dubbo.config.ApplicationConfig;
import org.apache.dubbo.config.ReferenceConfig;
import org.apache.dubbo.config.RegistryConfig;
import org.apache.dubbo.samples.api.GreetingsService;

public class Application {
    private static String zookeeperHost = System.getProperty("zookeeper.address", "127.0.0.1");

    public static void main(String[] args) {
        ReferenceConfig<GreetingsService> reference = new ReferenceConfig<>();
        reference.setApplication(new ApplicationConfig("first-dubbo-consumer"));
        reference.setRegistry(new RegistryConfig("zookeeper://" + zookeeperHost + ":2181"));
        reference.setInterface(GreetingsService.class);
        GreetingsService service = reference.get();
        String message = service.sayHi("dubbo");
        System.out.println(message);
    }
}

See consumer/Application.java on GitHub.

Build and run the consumer

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

The consumer will print out hi, dubbo on the screen.
