Dubbox和zk入门案例
Dobbox并没有在Maven仓库中存在,如果我们要导入Dubbox的依赖的话,就要将Dubbox安装到我们的maven仓库中

ZK的单机版安装请参考鄙人的另一篇博客

1.将Dubbox的压缩包下载之后进行解压
2.在Dubbox的根目录下
3.在上面的路径中输入cmd,进入命令提示符
4.执行命令:mvn clean install -Dmaven.test.skip=true
5.上一步完成之后在dubbo目录下会出现一个target目录
6.在命令提示符中执行下列的的命令,将刚才编译出来的jar文件安装到Maven仓库中,命令中红色的部分更改为自己Dubbox所在的目录
mvn install:install-file -Dfile=D:\Soft\dubbox-master\dubbo\target\dubbo-2.8.4.jar -DgroupId=com.alibaba -DartifactId=dubbo -Dversion=2.8.4 -Dpackaging=jar -DgeneratePom=true
7.启动ZK服务端,启动之后窗口不要关闭
以上的步骤完成之后,就ok,接下来就可以进行编码了
引入所要使用到的依赖,生产者和消费者一样,红色的依赖就是刚才安装到Maven仓库的Dubbox的依赖
<dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.8.4</version> </dependency> <!-- 添加zk客户端依赖 --> <dependency> <groupId>com.github.sgroschupf</groupId> <artifactId>zkclient</artifactId> <version>0.1</version> </dependency> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-jaxrs</artifactId> <version>3.0.7.Final</version> </dependency> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-client</artifactId> <version>3.0.7.Final</version> </dependency> <dependency> <groupId>javax.validation</groupId> <artifactId>validation-api</artifactId> <version>1.0.0.GA</version> </dependency> <!-- 如果要使用json序列化 --> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-jackson-provider</artifactId> <version>3.0.7.Final</version> </dependency> <!-- 如果要使用xml序列化 --> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-jaxb-provider</artifactId> <version>3.0.7.Final</version> </dependency> <!-- 如果要使用netty server --> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-netty</artifactId> <version>3.0.7.Final</version> </dependency> <!-- 如果要使用Sun HTTP server --> <dependency> <groupId>org.jboss.resteasy</groupId> <artifactId>resteasy-jdk-http</artifactId> <version>3.0.7.Final</version> </dependency> <!-- 如果要使用tomcat server --> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-core</artifactId> <version>8.0.11</version> </dependency> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-logging-juli</artifactId> <version>8.0.11</version> </dependency> <dependency> <groupId>com.esotericsoftware.kryo</groupId> <artifactId>kryo</artifactId> <version>2.24.0</version> </dependency> <dependency> <groupId>de.javakaffee</groupId> <artifactId>kryo-serializers</artifactId> <version>0.26</version> </dependency> <dependency> <groupId>de.ruedigermoeller</groupId> <artifactId>fst</artifactId> <version>1.55</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.3.3</version> </dependency> <dependency> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty</artifactId> <version>7.0.0.pre5</version> </dependency>
生产者和消费者都需要使用的接口
package com.yjc.service; import javax.ws.rs.Consumes; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.core.MediaType; @Path("/user") public interface UserService { @GET @Path("/getUser/{id}") @Consumes({ MediaType.APPLICATION_JSON }) public String getUser(@PathParam("id") Integer id); }
生产者中的接口实现类
package com.yjc.service.impl; import com.yjc.service.UserService; public class UserServiceImpl implements UserService { @Override public String getUser(Integer id) { System.out.println("dubbox发布----UserService类中的getUser方法,参数----"+id); return "dubbox"; } }
生产者中的配置文件applicationContext.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" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" 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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 提供方应用信息，用于计算依赖关系 --> <dubbo:application name="app-provider"/> <!-- 使用zookeeper注册中心暴露服务地址 --> <!-- <dubbo:registry address="192.168.118.3:2181,192.168.118.4:2181,192.168.118.5:2181" protocol="zookeeper" />--> <dubbo:registry address="127.0.0.1:2181" protocol="zookeeper" /> <dubbo:protocol name="rest" port="8081" /> <!-- 声明需要暴露的服务接口 --> <dubbo:service interface="com.yjc.service.UserService" ref="iUserService" /> <bean id="iUserService" class="com.yjc.service.impl.UserServiceImpl"/> </beans>
生产者测试类
import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import java.io.IOException; public class AppTest { public static void main(String[] args) throws IOException { ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml"); System.out.println("duboox 注册成功!"); System.in.read(); } }
消费者中的配置文件applicationContext.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" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" 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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 提供方应用信息，用于计算依赖关系 --> <dubbo:application name="app-provider"/> <!-- 使用zookeeper注册中心暴露服务地址 --> <dubbo:registry address="127.0.0.1:2181" protocol="zookeeper" /> <!-- 声明需要暴露的服务接口 --> <dubbo:reference interface="com.yjc.service.UserService" id="iUserService" /> </beans>
消费者中的测试类
package com.yjc; import static org.junit.Assert.assertTrue; import com.yjc.service.UserService; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import java.io.IOException; /** * Unit test for simple App. */ public class AppTest { public static void main(String[] args) throws IOException { ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml"); UserService userService = (UserService)ctx.getBean("iUserService"); String user = userService.getUser(100); System.out.println("消费者消费的参数-----"+user); System.in.read(); } }
最后先启动生产者的测试类,然后启动消费者的测试类这样就大功告成了
