Spring Boot 整合 Dubbo和Zookeeper

环境介绍

• zookeeper 安装
• dubbo-admin 查看管理注册中心服务提供者和消费者

Zookeeper 安装

http://zookeeper.apache.org/releases.html

下载最新安装包，文件格式是tar.gz，可见Apache还是推荐在Linux上使用，但也提供了在windows上使用的脚本。 
解压之后，修改数据和日志配置，注意在3.5.3版本上，conf文件夹里不在直接提供zoo.cfg，而是提供了一个example，zoo_sample.cfg。复制重命名为zoo.cfg，然后修改data位置新增log位置。注意，windows目录要用//分割。

dataDir=D:\\software\\zookeeper-3.5.3-beta\\zookeeper\\data
dataLogDir=D:\\software\\zookeeper-3.5.3-beta\\zookeeper\\log

• 修改zkEnv.cmd 
  

  防止win10 闪退,注意双引号的位置

if not exist "%JAVA_HOME%\bin\Java.exe"

set JAVA="%JAVA_HOME%\bin\java"

启动

使用zkServer.cmd启动Zookeeper即可。注意Zookeeper是运行在8080端口，服务接口是2181

Dubbo admin 搭建

https://github.com/alibaba/dubbo

https://github.com/dangdangdotcom/dubbox

下载dubbo，执行

mvn install -D maven.test.skip=true

然后在dubbo-admin下执行

mvn package -D maven.skip.test=true

打war包，发布到tomcat下，注意修改tomcat端口8081

创建主maven项目

pom.xml

<?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"
    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.rencc.dubbo</groupId>
    <artifactId>dubbo-spring-study</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>pom</packaging>

    <modules>
        <module>dubbo-provider</module>
        <module>dubbo-consumer</module>
    </modules>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.8</java.version>
    </properties>

</project>

创建子spring boot项目

• dubbo-provider 服务提供者

在application.properties 里设置端口，目前8080和8081已被使用

server.port=8090

添加dubbo的配置文件

<?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">

    <!-- 配置可参考 http://dubbo.io/User+Guide-zh.htm -->
    <!-- 服务提供方应用名，用于计算依赖关系 -->
    <dubbo:application name="dubbo-provider" owner="dubbo-provider" />

    <!-- 定义 zookeeper 注册中心地址及协议 -->
    <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" client="zkclient" />

    <!-- 定义 Dubbo 协议名称及使用的端口，dubbo 协议缺省端口为 20880，如果配置为 -1 或者没有配置 port，则会分配一个没有被占用的端口 -->
    <dubbo:protocol name="dubbo" port="-1" />

    <!-- 声明需要暴露的服务接口 -->
    <dubbo:service interface="com.rencc.dubbo.provider.service.DemoService"
        ref="demoService" timeout="10000" />

    <!-- 和本地 bean 一样实现服务 -->
    <bean id="demoService" class="com.rencc.dubbo.provider.serviceImpl.DemoServiceImpl" />

</beans>

DemoService 接口和实现类

package com.rencc.dubbo.provider.service;

public interface DemoService {
    String sayHello(String name);
}





package com.rencc.dubbo.provider.serviceImpl;

import com.rencc.dubbo.provider.service.DemoService;

public class DemoServiceImpl implements DemoService {

    public String sayHello(String name) {
        return "Welcome to Dubbo, Hello " + name;
    }

}

• dubbo-consumer 服务消费者 
  在此仅贴出dubbo代码配置。

    <!-- 消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 -->

    <!-- 定义 zookeeper 注册中心地址及协议 -->
