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

一、为啥整合 Dubbo 实现 SOA

解压 ZooKeeper

tar zxvf zookeeper-3.4.8.tar.gz

在 conf 目录新建 zoo.cfg ，照着该目录的 zoo_sample.cfg 配置如下。

cd zookeeper-3.3.6/conf
vim zoo.cfg

zoo.cfg 代码如下（自己指定 log 文件目录）：

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

在 bin 目录下，启动 ZooKeeper：

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

然后，Maven 编译安装这个工程：

cd springboot-learning-example
mvn cleaninstall

右键运行 springboot-dubbo-client 工程 ClientApplication 应用启动类的 main 函数。Console 中出现如下：

...

City{id=1, provinceId=2, cityName=温岭, description=是我的故乡}

pom.xml 中依赖了 spring-boot-starter-dubbo 工程，该项目地址是 https://github.com/teaey/spring-boot-starter-dubbo。pom.xml 配置如下

@SpringBootApplication
public class ClientApplication {
   public static void main(String[] args) {
       // 程序启动入口
       // 启动嵌入式的 Tomcat 并初始化 Spring 环境及其各 Spring 组件
       ConfigurableApplicationContext run = SpringApplication.run(ClientApplication.class, args);
       CityDubboConsumerService cityService = run.getBean(CityDubboConsumerService.class);
       cityService.printCity();
