因为要增加zookeeper的注册管理，所以如果有可用的zookeeper就用可用的zookeeper，没有可以按照如下的安装去本地安装一个。

特别注意：zookeeper的服务端和本地调用客户端的jar包版本最好要一致，否则会出现意想不到的惊喜。

本人使用的zookeeper 是3.3.6 版本

项目结构图

服务端

applicationProvider.xml

[html] view plaincopy

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xsi:schemaLocation="http://www.springframework.org/schema/beans

">
<dubbo:application name="hello-world-app" />
<dubbo:registry protocol="zookeeper" address="192.9.145.19:2181,192.9.145.19:2182,192.9.145.19:2183" />
<dubbo:protocol name="dubbo" port="20880" />
<dubbo:service interface="com.mor.server.dubbo.service.DemoServer"
ref="demoService" />
<bean id="demoService" class="com.mor.server.dubbo.service.DemoServerImpl" />
</beans>

客户端：

applicationConsumer.xml

[html] view plaincopy

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://code.alibabatech.com/schema/dubbo/dubbo.xsd
">
<dubbo:application name="consumer-of-helloworld-app" />

[html] view plaincopy

<dubbo:registry protocol="zookeeper" address="192.9.145.19:2181,192.9.145.19:2182,192.9.145.19:2183" />
<dubbo:reference id="demoService" interface="com.mor.server.dubbo.service.DemoServer" />
</beans>

在客户端要引入服务端生成的jar包

服务端代码：

demodubboserver\src\main\java\com\mor\server\dubbo\service\DemoServer.java

[java] view plaincopy

package com.mor.server.dubbo.service;
public interface DemoServer {
String sayHello(String str);
}

demodubboserver\src\main\java\com\mor\server\dubbo\service\DemoServerImpl.java

[java] view plaincopy

package com.mor.server.dubbo.service;
import java.util.Date;
public class DemoServerImpl implements DemoServer {
public String sayHello(String str) {
str = "Hello " + str + "2:" + new Date();
System.out.println("server:" + str);
return str;
}
}

demodubboserver\src\main\java\com\mor\main\Main.java

[java] view plaincopy

package com.mor.main;
import java.io.IOException;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Main {
public static void main(String[] args) throws IOException {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "applicationProvider.xml" });
context.start();
System.out.println("按任意键退出");
System.in.read();
}
}

log4j.properties

[html] view plaincopy

log4j.appender.Stdout=org.apache.log4j.ConsoleAppender
log4j.appender.Stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.Stdout.layout.conversionPattern=%-5p - %-26.26c{1} - %m\n
log4j.rootLogger=INFO,Stdout
log4j.logger.org.apache.wicket=INFO
log4j.logger.org.apache.wicket.protocol.http.HttpSessionStore=INFO
log4j.logger.org.apache.wicket.version=INFO
log4j.logger.org.apache.wicket.RequestCycle=INFO

客户端代码：

[java] view plaincopy

package com.mor.client.dubbo.action;
import java.util.Date;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.mor.server.dubbo.service.DemoServer;
public class ChatAction {
public void SayHello(){
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "applicationConsumer.xml" });
context.start();
DemoServer demoServer = (DemoServer) context.getBean("demoService");
System.out.println("client:"+demoServer.sayHello("Morning"+"1:"+new Date())+"3:"+new Date());
}
}

dubboclient\src\main\java\com\mor\client\dubbo\main\Main.java

[java] view plaincopy

package com.mor.client.dubbo.main;
import com.mor.client.dubbo.action.ChatAction;
public class Main {
public static void main(String[] args){
ChatAction act = new ChatAction();
act.SayHello();
}
}

============启动顺序================
1.先启动 zookeeper 集群

2.在启动服务端

3.最后启动客户端调用服务

服务端打包
