Dubbo 生产者配置及启动(一）

一、生产者简介：

    （1） 服务提供方
    （2）伴随启动容器
    （3）服务注册

二、加载过程

三、应用类型

    Java Application（Main 函数启动的java进程）

    Maven：

<dependency>     <groupId>com.alibaba</groupId>     <artifactId>dubbo</artifactId>     <version>2.5.5</version></dependency>

四、配置生产者XML

五、my-provider工程

(5.1) 将dubbo-api1 : 存放公共接口； 最终会打为jar包，供consumer和provider1引用。

        pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.hlx.dubbo</groupId><artifactId>my-provider</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>my-provider</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><dependency><groupId>com.alibaba</groupId><artifactId>dubbo</artifactId><version>2.5.5</version></dependency><dependency><groupId>org.apache.zookeeper</groupId><artifactId>zookeeper</artifactId><version>3.4.8</version></dependency><dependency><groupId>com.github.sgroschupf</groupId><artifactId>zkclient</artifactId><version>0.1</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>4.3.10.RELEASE</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version></dependency></dependencies></project>

(5.2) dubbo-properties

dubbo.container=spring#set dubbo Sping load setting xmlsdubbo.spring.config=classpath:spring-dubbo-provider.xmldubbo.protocol.name=dubbodubbo.protocol.port=20880

(5.3)spring-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"><!--1 应用的名称 --><dubbo:application name="my-provider" /><!--2 指定注册中心 地址，协议 --><dubbo:registry id="zk1" address="127.0.0.1:2181"protocol="zookeeper" /><!--3 指定协议名称,端口号 --><dubbo:protocol id="mydubbo" name="dubbo" port="20880" /><!--4 服务提供者（ 默认的可以不配置） --><!-- <dubbo:provider register="zk1" protocol="mydubbo"/> --><!--5 服务类 接口，实现的类；--><bean id="userService" class="com.hlx.provider.UserServiceImpl"/><dubbo:service interface="com.hlx.service.UserService" ref="userService"  /></beans>

(5.4)UserServiceImpl实现接口的类 

public class UserServiceImpl implements UserService {public String sayHello(String name) {System.out.println("["+ new SimpleDateFormat("HH:mm:ss").format(new Date())+ "] Hello " + name + ", request from consumer: "+ RpcContext.getContext().getRemoteAddress());return "Hello " + name + ", response form provider: "+ RpcContext.getContext().getLocalAddress();}}

（5.5）Main类

package com.hlx.provider;/** * 该类是dubbo框架提供，作用是启动dubbo服务，dubbo会在启动服务时， * 读取classpath下一个名为dubbo.properties文件的属性值 *  * @author Administrator *  */public class Main {public static void main(String[] args) {com.alibaba.dubbo.container.Main.main(args);}}

(5.6)启动zookeeper注册中心服务

(5.7)启动生产者

(5.8)启动zookeeper客户端查看服务是否被注册
