Springboot 整合 Dubbo/ZooKeeper 詳解 SOA 案例 | 泥瓦匠BYSocket

一、為啥整合 Dubbo 實現(xiàn) SOA

解壓 ZooKeeper

tar zxvf zookeeper-3.4.8.tar.gz

在 conf 目錄新建 zoo.cfg ，照著該目錄的 zoo_sample.cfg 配置如下。

cd zookeeper-3.3.6/conf
vim zoo.cfg

zoo.cfg 代碼如下（自己指定 log 文件目錄）：

tickTime=2000
dataDir=/javaee/zookeeper/data 
dataLogDir=/javaee/zookeeper/log
clientPort=2181

在 bin 目錄下，啟動 ZooKeeper：

cd zookeeper-3.3.6/bin
./zkServer.sh start

然后，Maven 編譯安裝這個工程：

cd springboot-learning-example
mvn cleaninstall

右鍵運行 springboot-dubbo-client 工程 ClientApplication 應用啟動類的 main 函數(shù)。Console 中出現(xiàn)如下：

...

City{id=1, provinceId=2, cityName='溫嶺', description='是我的故鄉(xiāng)'}

pom.xml 中依賴了 spring-boot-starter-dubbo 工程，該項目地址是 https://github.com/teaey/spring-boot-starter-dubbo。pom.xml 配置如下
