1.新建两个maven项目,一个是服务器端的,一个是客户端的
2.服务器端pom.xml添加jar
<dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.5.3</version> </dependency> <dependency> <groupId>org.javassist</groupId> <artifactId>javassist</artifactId> <version>3.18.1-GA</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.15</version> <exclusions> <exclusion> <groupId>com.sun.jdmk</groupId> <artifactId>jmxtools</artifactId> </exclusion> <exclusion> <groupId>com.sun.jmx</groupId> <artifactId>jmxri</artifactId> </exclusion> <exclusion> <artifactId>jms</artifactId> <groupId>javax.jms</groupId> </exclusion> <exclusion> <artifactId>mail</artifactId> <groupId>javax.mail</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> <version>2.5.6.SEC03</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.6</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.6.1</version> </dependency> <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> <version>3.4.5</version> <type>pom</type> </dependency> <dependency> <groupId>com.101tec</groupId> <artifactId>zkclient</artifactId> <version>0.4</version> </dependency>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
3.编写一个接口和一个实现类。
package com.mu.dubbo.service; /** * Created by mdt on 17-6-26. */ public interface SayHelloToClient { public String sayHello(String hello); }
package com.mu.dubbo.service.impl; import com.mu.dubbo.service.SayHelloToClient; /** * Created by mdt on 17-6-26. */ public class SayHelloToClientImpl implements SayHelloToClient { public String sayHello(String hello){ System.out.println("我接收到了:" + hello); return hello + "你也好啊!!!" ; } }
4.创建配置文件applicationProvider.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 "> <!--应用名称--> <dubbo:application name="hello-world" /> <!-- 注册地址 --> <dubbo:registry address="multicast://224.5.6.7:1234" /> <!-- 接口的位置 --> <dubbo:service interface="com.mu.dubbo.service.SayHelloToClient" ref="demoService" executes="10" /> <!-- 实现bean,客户端应用的bean就以这个id名称为主 --> <bean id="demoService" class="com.mu.dubbo.service.impl.SayHelloToClientImpl" /> </beans>
5.编写主函数,启动服务用。
package com.mu.dubbo.main; import org.springframework.context.support.ClassPathXmlApplicationContext; /** * Created by mdt on 17-6-26. */ public class MyMain { public static void main(String[] args) throws Exception { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "applicationProvider.xml" }); context.start(); System.out.println("按任意键退出"); System.in.read(); } }
6.客户端pom.xml。
<dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.5.3</version> </dependency> <dependency> <groupId>org.javassist</groupId> <artifactId>javassist</artifactId> <version>3.18.1-GA</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.15</version> <exclusions> <exclusion> <groupId>com.sun.jdmk</groupId> <artifactId>jmxtools</artifactId> </exclusion> <exclusion> <groupId>com.sun.jmx</groupId> <artifactId>jmxri</artifactId> </exclusion> <exclusion> <artifactId>jms</artifactId> <groupId>javax.jms</groupId> </exclusion> <exclusion> <artifactId>mail</artifactId> <groupId>javax.mail</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> <version>2.5.6.SEC03</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.6</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.6.1</version> </dependency> <dependency> <groupId>com.github.adyliu</groupId> <artifactId>zkclient</artifactId> <version>2.0</version> </dependency> <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> <version>3.4.5</version> <type>pom</type> </dependency> <dependency> <groupId>com.mu.dubbo</groupId> <artifactId>mu-dubbo-server</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency></dependencies>
以下的这点不太一样,从服务端pom.xml里面拷贝。
<dependency> <groupId>com.mu.dubbo</groupId> <artifactId>mu-dubbo-server</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency>
7.客户端调用程序。
package com.mu.dubbo.client; import com.mu.dubbo.service.SayHelloToClient; import org.springframework.context.support.ClassPathXmlApplicationContext; /** * Created by mdt on 17-6-26. */ public class MyClient { public void sayHello(){ ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "applicationConsumer.xml" }); context.start(); //获取服务器那边的bean SayHelloToClient demoService = (SayHelloToClient) context.getBean("demoService"); System.out.println(demoService.sayHello("huahua")); } }
8.客户端主函数。
package com.mu.dubbo.test; import com.mu.dubbo.client.MyClient; /** * Created by mdt on 17-6-26. */ public class AppTest{ public static void main(String[] args) { MyClient myClient = new MyClient(); myClient.sayHello(); } }
9.配置applicationConsumer.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 "> <!-- consumer application name --> <dubbo:application name="consumer-of-helloworld-app" /> <!-- registry address, used for consumer to discover services --> <dubbo:registry address="multicast://224.5.6.7:1234" /> <dubbo:consumer timeout="5000" /> <!-- which service to consume? --> <dubbo:reference id="demoService" interface="com.mu.dubbo.service.SayHelloToClient"/> </beans>
先启动服务端主函数,再启动客户端主函数。
