先把zookeeper在本地給安裝好,html
這裏的話講述了兩個工程一個工程是提供服務的,一個工程是調用服務的,由於dubbo是跟spring進行無縫鏈接的,故功能配置在spring的配置文件中,跟spring進行整合開發java
一、工程是以maven進行構建的,使用的jar包以下:spring
二、服務提供者的工程api
a、dubbo-demo-api 定義接口緩存
[java] view plain copy服務器
- public interface IProcessData {
- public String deal(String data);
- }
b、dubbo-demo-provider 服務提供者mvc
[java] view plain copyapp
- public class ProcessDataImpl implements IProcessData {
-
- /*
- * @see com.xxx.bubbo.provider.IProcessData#deal(java.lang.String)
- */
- @Override
- public String deal(String data) {
- try {
- Thread.sleep(1000);
- } catch (InterruptedException e) {
- e.printStackTrace();
- }
- return "Finished:" + data;
- }
- }
c、applicationProvider.xml配置框架
[html] view plain copymaven
- <?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
- http://www.springframework.org/schema/beans/spring-beans.xsd
- http://code.alibabatech.com/schema/dubbo
- http://code.alibabatech.com/schema/dubbo/dubbo.xsd
- ">
-
- <!-- Application name -->
- <dubbo:application name="hello-world-app" />
-
- <!-- registry address, used for service to register itself -->
- <dubbo:registry address="zookeeper://127.0.0.1:2181" />
-
- <!-- expose this service through dubbo protocol, through port 20880 -->
- <!--
- <dubbo:protocol name="dubbo" port="20880" />
-
- <dubbo:protocol name="dubbo" port="9090" server="netty"
- client="netty" codec="dubbo" serialization="hessian2" charset="UTF-8"
- threadpool="fixed" threads="100" queues="0" iothreads="9" buffer="8192"
- accepts="1000" payload="8388608" />
- -->
- <!-- Service interface Concurrent Control -->
- <dubbo:service interface="com.huangjie.dubbo_Service.service.IProcessData"
- ref="demoService" executes="10" />
-
- <!-- Default Protocol -->
- <!--
- <dubbo:protocol server="netty" />
- -->
-
- <!-- designate implementation -->
- <bean id="demoService" class="com.huangjie.dubbo_Service.service.impl.ProcessDataImpl" />
-
- </beans>
d、啓動服務
[java] view plain copy
- public class DubboProviderMain {
- public static void main(String[] args) throws Exception {
- ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
- new String[]{"applicationProvider.xml"});
- context.start();
-
- System.out.println("Press any key to exit.");
- System.in.read();
- }
- }
三、服務調用者的工程
a、調用類
[java] view plain copy
- public class ConsumerThd implements Runnable {
-
- /*
- * @see java.lang.Runnable#run()
- */
- @Override
- public void run() {
- ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
- new String[]{"applicationConsumer.xml"});
- context.start();
-
- IProcessData demoService = (IProcessData) context.getBean("demoService"); // get
- // service
- // invocation
- // proxy
- String hello = demoService.deal("nihao"); // do invoke!
-
- System.out.println(Thread.currentThread().getName() + " "+hello);
- }
-
- public static void main(String[] args) {
- new Thread(new ConsumerThd()).start();
- /**
- * 輸出結果:
- * Thread-0 Finished:nihao
- */
- }
- }
b、applicationConsumer.xml配置
[html] view plain copy
- <?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
- http://www.springframework.org/schema/beans/spring-beans.xsd
- http://code.alibabatech.com/schema/dubbo
- http://code.alibabatech.com/schema/dubbo/dubbo.xsd
- ">
-
- <!-- consumer application name -->
- <dubbo:application name="consumer-of-helloworld-app" />
-
- <!-- registry address, used for consumer to discover services -->
- <dubbo:registry address="zookeeper://127.0.0.1:2181" />
- <dubbo:consumer timeout="5000"/>
- <!-- which service to consume? -->
- <dubbo:reference id="demoService" interface="com.huangjie.dubbo_Service.service.IProcessData" />
- </beans>
四、最後須要把zookeeper的服務給啓動,在zookeeper安裝文件夾下面的bin目錄裏面的zkServer.cmd給點擊運行。不要關閉窗口,保持服務運行
這樣整個調用就完成了,這樣的好處是隻要遠程提供ip地址及端口號,以及對外調用的類,客戶端就能夠調用,客戶端沒必要知道服務端的地址之類的
並且服務端能夠開多個zookeeper服務,這樣若是其中一個zookeeper 服務死掉了,其餘服務還能正常運行
