Dubbo is a distributed service framework enpowers applications with service import/export capability with high performance RPC.

It's composed of three kernel 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

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
       - edit: export PATH=$PATH:~/apache-maven-2.2.1/bin
    source .bash_profile

1. Checkout the dubbo source code:

    cd ~
    git clone https://github.com/alibaba/dubbo.git dubbo

    git checkout -b dubbo-2.4.0
    git checkout master

2. Import the dubbo source code to eclipse project:

    cd ~/dubbo
    mvn eclipse:eclipse
    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

3. Build the dubbo binary package:

    cd ~/dubbo
    mvn clean install -Dmaven.test.skip
    cd dubbo/target
    ls

4. Install the demo provider:

    cd ~/dubbo/dubbo-demo-provider/target
    tar zxvf dubbo-demo-provider-2.4.0-assembly.tar.gz
    cd dubbo-demo-provider-2.4.0/bin
    ./start.sh

5. Install the demo consumer:

    cd ~/dubbo/dubbo-demo-consumer/target
    tar zxvf dubbo-demo-consumer-2.4.0-assembly.tar.gz
    cd dubbo-demo-consumer-2.4.0/bin
    ./start.sh
    cd ../logs
    tail -f stdout.log

6. Install the simple monitor:

    cd ~/dubbo/dubbo-simple-monitor/target
    tar zxvf dubbo-simple-monitor-2.4.0-assembly.tar.gz
    cd dubbo-simple-monitor-2.4.0/bin
    ./start.sh
    http://127.0.0.1:8080

7. Install the simple registry:
