Apache Dubbo (incubating) is a high-performance, java based open source RPC framework. Please visit [official site ](http://dubbo.incubator.apache.org) for quick start and documentations, as well as [Wiki](https://github.com/apache/incubator-dubbo/wiki) for news, FAQ, and release notes.

We are now collecting dubbo user info in order to help us to improve dubbo better, pls. kindly help us by providing yours on [issue#1012: Wanted: who's using dubbo](https://github.com/apache/incubator-dubbo/issues/1012), thanks :)

## Architecture

![Architecture](http://dubbo.apache.org/img/architecture.png)

## Features

* Transparent interface based RPC
* Intelligent load balancing
* Automatic service registration and discovery
* High extensibility
* Runtime traffic routing
* Visualized service governance

## Getting started

### Maven dependency

```xml
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>dubbo</artifactId>
    <version>2.6.2</version>
</dependency>
```

### Defining service interfaces

```java
package org.apache.dubbo.demo;

public interface DemoService {
    String sayHello(String name);
}
```

### Implement interface in service provider

```java
package org.apache.dubbo.demo.provider;
 
import org.apache.dubbo.demo.DemoService;
 
public class DemoServiceImpl implements DemoService {
    public String sayHello(String name) {
        return "Hello " + name;
    }
}
```

### Starting service provider

```java
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 Provider {

    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();
    }
}
```

### Call remote service in consumer

```java
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 Consumer {
    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"));
    }
}
```
