dubbo服务基本搭建部署操作
dubbo服务基本搭建部署操作
1. 启动zookeeper:
(1)zookeeper下载地址:http://zookeeper.apache.org/;
(2)解压并修改配置
进入到zookeeper的conf目录,找到zoo_sample.cfg文件将其重命名为zoo.cfg,然后打开该文件,
将其中的dataDir和dataLogDir修改如下:
dataDir=E:\\test-project\\dubbo-demo\\data
dataLogDir=E:\\test-project\\dubbo-demo\\log
2.dubbo接口服务api项目(其实该步上传jar包到Nexus可以用provider的jar包):
注意:将其pom.xml中的打包方式改为jar;
public interface DemoService {
String sayHello(String name);
}
【pom.xml配置】:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3.dubbo服务提供者provider项目:
【pom.xml】配置三个核心依赖:
<!--api接口依赖-->
<dependency>
<groupId>com.dubbo.api</groupId>
<artifactId>api</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.alibaba/dubbo -->
<!--dubbo依赖-->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<version>2.5.3</version>
</dependency>
<!--zookeeper客服端依赖-->
<dependency>
<groupId>com.101tec</groupId>
<artifactId>zkclient</artifactId>
<version>0.10</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.0.5.RELEASE</version>
</dependency>
【接口实现类】:
public class DemoServiceImpl implements DemoService {
@Override
public String sayHello(String name) {
return "Hello " + name;
}
}
【provider.xml】配置:
<?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">
<!--定义了提供方应用信息,用于计算依赖关系;在 dubbo-admin 或 dubbo-monitor 会显示这个名字,方便辨识-->
<dubbo:application name="demo-provider" owner="nz" organization="dubbox"/>
<!--使用 zookeeper 注册中心暴露服务,注意要先开启 zookeeper-->
<dubbo:registry address="zookeeper://localhost:2181"/>
<!-- 用dubbo协议在20880端口暴露服务 -->
<dubbo:protocol name="dubbo" port="20880" />
<!--使用 dubbo 协议实现定义好的 api.PermissionService 接口-->
<dubbo:service interface="com.dubbo.api.service.DemoService" ref="demoService" protocol="dubbo" />
<!--具体实现该接口的 bean-->
<bean id="demoService" class="com.dubbo.provider.service.impl.DemoServiceImpl"/>
</beans>
【Provider用于启动项目Java代码】:启动服务提供者
public static void main(String[] args) throws IOException {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("provider.xml");
context.start();
System.out.println("dubbo服务提供端已启动....");
// 按任意键退出
System.in.read();
}
4.dubbo消费者consumer项目:
【pom.xml】配置三个核心依赖等同于 服务提供者:
【Consumer用于启动项目Java代码】:启动消费者:
public static void main(String[] args) throws IOException {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext( "consumer.xml" );
context.start();
System.out.println("dubbo服务消费端已启动...");
// 获取远程服务代理
DemoService demoService = (DemoService)context.getBean( "demoService" );
// 执行远程方法
String hello = demoService.sayHello( "world" );
// 显示调用结果
System.out.println(hello);
// 按任意键退出
System.in.read();
}
【consumer.xml】消费者配置:
<?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">
<dubbo:application name="demo-consumer" owner="nz" organization="dubbox"/>
<!--向 zookeeper 订阅 provider 的地址,由 zookeeper 定时推送-->
<dubbo:registry address="zookeeper://localhost:2181"/>
<!--使用 dubbo 协议调用定义好的 api.PermissionService 接口-->
<dubbo:reference id="demoService" interface="com.dubbo.api.service.DemoService"/>
</beans>
5.dubbo-admin管理控制台:
通过dubbo-admin可以更好的管理dubbo服务,将dubbo-admin-2.6.0.war复制到tomcat的webapps目录下。然后启动tomcat,访问
http://localhost:8080/dubbo-admin-2.6.0/(用户名和密码默认root)
通过网页进行管理dubbo服务 :
