springboot+dubbo+zookeeper微服務demo搭建

從業3年了,最近一年不知怎麼了,陰差陽錯的就這麼過去了,貌似有好長時間沒有寫過代碼了,自認爲是開發人員的我,感覺有點對不起自己了;就在今天早上,突然心血來潮,想要擼一下代碼,找找當年的感覺,於是決定回顧一下dubbo微服務的搭建過程,當然整個demo只是入門級,沒有什麼難點,就是找找滿足感,娛樂自己一下;

先用maven創建一個parent項目,這一步傻瓜式創建,起個名字,點點鼠標就完成了,我給的名字是:dubbo-spring-demo

在該項目下創建兩個maven模塊,分別爲dubbo-consumer.dubbo-provider

分別引入所需要的依賴,dubbo-consumer的pom.xml如下

在parent的pom.xml中添加這兩個模塊

客戶端及服務端項目結構:

application.properties文件目前只配置服務端口號;

consumers.xml文件配置如下:

<?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="dubbo-consumer" owner="dubbo-consumer" />
	
	<!-- 定義 zookeeper 註冊中心地址及協議 -->
	<dubbo:registry protocol="zookeeper" address="0.0.0.0:2181" client="zkclient" />
	
	<!-- 生成遠程服務代理，可以和本地 bean 一樣使用 demoService -->
	<dubbo:reference id="demoService" interface="com.minbo.dubbo.provider.DemoService" />
	
</beans>

providers.xml文件內容如下:

<?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">
       
	<!-- 配置可參考 http://dubbo.io/User+Guide-zh.htm -->
	 <!--服務提供方應用名，用於計算依賴關係 -->
	<dubbo:application name="dubbo-provider" owner="dubbo-provider" />
	
	<!-- 定義 zookeeper 註冊中心地址及協議 -->
	<dubbo:registry protocol="zookeeper" address="0.0.0.0:2181" client="zkclient" />
		
	<!-- 定義 Dubbo 協議名稱及使用的端口，dubbo 協議缺省端口爲 20880，如果配置爲 -1 或者沒有配置 port，則會分配一個沒有被佔用的端口 -->
	<dubbo:protocol name="dubbo" port="-1" />
	
	<!-- 聲明需要暴露的服務接口 -->
	<dubbo:service interface="com.minbo.dubbo.provider.DemoService"
		ref="demoService" timeout="10000" />
		
	<!-- 和本地 bean 一樣實現服務 -->
	<bean id="demoService" class="com.minbo.dubbo.provider.DemoServiceImpl" />
	
</beans>

我的zookeeper是配置在linux雲服務器上的哈;

可能缺點啥,只是記錄一下自己的消化過程;
