Spring Boot 整合 Dubbo和Zookeeper
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

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

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;
