Ali Dubbo Framework Use series: creation and use of service providers and consumers

Create a new MAVEN project

Create a service interface

Package Com.pcx.dubbo_facade;public interface Demoservice {    string SayHello (string name);}

Run the clean install package Dubbo-facade

Next create the Dubbo-provider project

In the Pom.xml, refer to the jar package of the service interface just now

<span style= "White-space:pre" ></span><dependency><groupId>com.pcx</groupId>    <span style= "White-space:pre" ></span><artifactId>dubbo-facade</artifactId> <version >0.0.1-SNAPSHOT</version></dependency>

Writing service Implementation classes

Package Com.pcx.dubbo_prodiver;import Org.springframework.stereotype.service;import Com.pcx.dubbo_facade. Demoservice; @Service ("Demoservice") public class Demoserviceimpl implements Demoservice {public string SayHello (string Name) {return "Hello" + Name;}}

Write two spring profiles under the resource directory

Dubbo-provider.xml

<?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 "><!--define app name--><dubbo:application name=" Dubbo-demo-provider "/><!--ZK Registry Address-- <dubbo:registry protocol= "Zookeeper" address= "192.168.1.10:2181"/><!--exposed service with Dubbo protocol on 21000 Ports-->< Dubbo:protocol name= "Dubbo" port= "21000"/><!--Configuration Service Interface--><dubbo:service interface= "Com.pcx.dubbo_facade .

Spring-context.xml

<?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:p= "http://www.springframework.org/schema/p" xmlns:context= "Http://www.springframework.org/schema/context" xmlns:aop= "HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP" xmlns:tx= " Http://www.springframework.org/schema/tx "xsi:schemalocation=" Http://www.springframework.org/schema/beans http:              Www.springframework.org/schema/beans/spring-beans-3.2.xsd HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP             Http://www.springframework.org/schema/aop/spring-aop-3.2.xsd HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/TX Http://www.springframework.org/schema/tx/spring-tx-3.2.xsd Http://www.springframework.org/schema/cont Ext http://www.springframework.org/schema/context/spring-context-3.2.xsd "default-autowire=" ByName "Default-laz Y-init= "false" ><!--Configure Bean--><conte in a commented mannerXt:annotation-config/><!--Configure the path of the package to be scanned--><context:component-scan base-package= "COM.PCX"/>< Import resource= "Dubbo-provider.xml"/></beans>

Writing test classes under Src/test/java path start the Dubbo service

Package Com.pcx.dubbo_prodiver;import Org.apache.commons.logging.log;import Org.apache.commons.logging.LogFactory ; Import Org.springframework.context.support.classpathxmlapplicationcontext;public class Dubboprovider {private Static final Log log = Logfactory.getlog (dubboprovider.class);p ublic static void Main (string[] args) {try {Classpathxmlap Plicationcontext context = new Classpathxmlapplicationcontext ("Classpath:spring-context.xml"); Context.start ();} catch (Exception e) {log.error ("= = Dubboprovider Context start error:", e);} Synchronized (Dubboprovider.class) {while (true) {try {DubboProvider.class.wait ()} catch (Interruptedexception e) { Log.error ("= = Synchronized Error:", e);}}}}

Running this test class, we can see our exposed service in the Dubbo console

Create a new project named Dobbo-consumer

A jar package that relies on our service interface under Pom.xml

<span style= "White-space:pre" ></span><dependency><groupId>com.pcx</groupId>    <artifactId>dubbo-facade</artifactId> <version>0.0.1-snapshot</version></dependency >

Two new spring profiles added under the src/main/resource/directory

Dubbo-consumer.xml

Write the test class that invokes the service in Src/test/java

Package Com.pcx.dubbo_consumer;import Org.apache.commons.logging.log;import Org.apache.commons.logging.LogFactory ; Import Org.springframework.context.support.classpathxmlapplicationcontext;import Com.pcx.dubbo_facade. Demoservice;public class Consumer {    private static final log log = Logfactory.getlog (Consumer.class);        public static void Main (string[] args) throws Interruptedexception {        Classpathxmlapplicationcontext context = new Cla Sspathxmlapplicationcontext ("Classpath:spring-context.xml");        Context.start ();        Demoservice Demoservice = (demoservice) context.getbean ("Demoservice");         String Hello = Demoservice.sayhello ("World");        Log.info ("print" +hello);                      Thread.Sleep (100000);    }}

Run the test class

Call succeeded

You can see the information in the Dubbo console at this time
