Dubbo is a distributed, high performance RPC framework enpowering applications with service import/export capabilities.

It's composed of three key parts:

• Remoting: a network communication framework provides sync-over-async and request-response messaging.
• Clustering: a remote procedure call abstraction with load-balancing/failover/clustering capabilities.
• Registry: a service directory framework for service registration and service event publish/subscription

For more details, please refer to wiki or dubbo.io.

Quick Start

Export remote service:

<bean id="barService" class="com.foo.BarServiceImpl" />
<dubbo:service interface="com.foo.BarService" ref="barService" />

Refer remote service:

<dubbo:reference id="barService" interface="com.foo.BarService" />
	
<bean id="barAction" class="com.foo.BarAction">
    <property name="barService" ref="barService" />
</bean>

Source Building

0. Install the git and maven command line:

yum install git or: apt-get install git cd ~ wget http://www.apache.org/dist//maven/binaries/apache-maven-2.2.1-bin.tar.gz tar zxvf apache-maven-2.2.1-bin.tar.gz vi .bash_profile append: export PATH=$PATH:~/apache-maven-2.2.1/bin source .bash_profile

0. Checkout the dubbo source code:

    ```sh
cd ~
git clone https://github.com/alibaba/dubbo.git dubbo
git checkout master
or: git checkout -b dubbo-2.4.0

0. Import the dubbo source code to eclipse project:

cd ~/dubbo mvn eclipse:eclipse

    Then configure the project in eclipse by following the steps below:
    * Eclipse -> Menu -> File -> Import -> Exsiting Projects to Workspace -> Browse -> Finish
    * Context Menu -> Run As -> Java Application:
        * dubbo-demo-provider/src/test/java/com.alibaba.dubbo.demo.provider.DemoProvider
        * dubbo-demo-consumer/src/test/java/com.alibaba.dubbo.demo.consumer.DemoConsumer
        * dubbo-monitor-simple/src/test/java/com.alibaba.dubbo.monitor.simple.SimpleMonitor
        * dubbo-registry-simple/src/test/java/com.alibaba.dubbo.registry.simple.SimpleRegistry
    * Edit Config:
        * dubbo-demo-provider/src/test/resources/dubbo.properties
        * dubbo-demo-consumer/src/test/resources/dubbo.properties
        * dubbo-monitor-simple/src/test/resources/dubbo.properties
        * dubbo-registry-simple/src/test/resources/dubbo.properties
