Idea環境下Dubbo+SpringMVC+ZooKeeper+Zkui例項程式
阿新 • • 發佈：2019-02-19
一、環境預備
由於要用到Dubbo和Zookeeper，所以需要提前將Dubbo+Zookeeper環境準備好。
啟動服務後登入：（使用者名稱/密碼： root/root、guest/guest）
啟動服務後登入：（使用者名稱/密碼： admin/manager）
二、用Idea工具搭建環境
具體步驟如下：
1.新建一個空的maven專案：
GroupId：com.dubbo，ArtifactId:Demo:
Project name:DubboDemo
點選完成。
2.在剛才的DubboDemo上建立一個Web專案（消費者）
右鍵-New-Module：
勾上Create from archetype，選擇maven-archetype-webapp，下一步。
填寫ArtifactId，如：comsumerdemo，下一步：
選擇Maven資訊，下一步：
完成！！！
3.在剛才的DubboDemo上建立一個專案（供應者）
下一步：
填寫ArtifactId，如：providerdemo，下一步：
完成！
三、框架程式碼結構詳情
1.DubboDemo空maven
除了pom.xml其他都可以刪除（如：src等），DubboDemo的pom.xml內容：
<?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.dubbo</groupId> <artifactId>Demo</artifactId> <packaging>pom</packaging> <version>1.0-SNAPSHOT</version> <modules> <module>consumerdemo</module> <module>providerdemo</module> </modules> </project>
2.供應者providerdemo
2-1，程式碼結構：
2-2，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"> <parent> <artifactId>Demo</artifactId> <groupId>com.dubbo</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>providerdemo</artifactId> <dependencies> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.5.3</version> </dependency> <dependency> <groupId>org.javassist</groupId> <artifactId>javassist</artifactId> <version>3.18.2-GA</version> </dependency> <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> <version>3.3.6</version> </dependency> <dependency> <groupId>com.github.sgroschupf</groupId> <artifactId>zkclient</artifactId> <version>0.1</version> </dependency> </dependencies> </project>
2-3，IProviderService介面：
package com.dubbo.service;
/**
* <p>Description:</p>
* <p>com.dubbo.service</p>
*
* @author smartdt
* @version 1.0
* @date 2018/5/21
*/
public interface IProviderService {
public String getString();
}
2-4，ProviderServiceImpl類：
package com.dubbo.service.impl;
import com.dubbo.service.IProviderService;
/**
* <p>Description:</p>
* <p>com.dubbo.service.impl</p>
*
* @author smartdt
* @version 1.0
* @date 2018/5/21
*/
public class ProviderServiceImpl implements IProviderService {
public String getString() {
return "Hello Dubbo~";
}
}
2-5，ProviderApplication類：
package com.dubbo;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import java.io.IOException;
/**
* <p>Description:</p>
* <p>com.dubbo</p>
*
* @author smartdt
* @version 1.0
* @date 2018/5/21
*/
public class ProviderApplication {
public static void main(String[] args) throws IOException {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("provider.xml");
context.start();
System.out.println("服務方開始提供服務~~~~~");
System.in.read();
}
}
2-6，provider.xml配置檔案：
<?xml version="1.0" encoding="UTF-8"?>

服務方開始提供服務~~~~~
2.再通過tomcat配置consumerdemo後啟動：
訪問：http://localhost:8000/dubbo/hi.do
控制檯：
22222222222222222222222
服務方：Hello Dubbo~3.dubbo admin控制檯
