分布式理论 | RPC | Spring Boot 整合 Dubbo + ZooKeeper
以下是一个简化的Spring Boot整合Dubbo和ZooKeeper的例子。
- 在
pom.xml
中添加依赖:
<dependencies>
<!-- Dubbo Spring Boot Starter -->
<dependency>
<groupId>org.apache.dubbo</groupId>
<artifactId>dubbo-spring-boot-starter</artifactId>
<version>2.7.3</version>
</dependency>
<!-- ZooKeeper Client -->
<dependency>
<groupId>org.apache.curator</groupId>
<artifactId>curator-framework</artifactId>
<version>2.12.0</version>
</dependency>
<!-- ZooKeeper Registry -->
<dependency>
<groupId>org.apache.dubbo</groupId>
<artifactId>dubbo-registry-zookeeper</artifactId>
<version>2.7.3</version>
</dependency>
</dependencies>
- 在
application.properties
或application.yml
中配置Dubbo和ZooKeeper:
# Dubbo Config
dubbo.application.name=demo-provider
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.protocol.name=dubbo
dubbo.protocol.port=20880
dubbo.scan.base-packages=com.example.service
- 创建服务接口:
public interface GreetingService {
String sayHello(String name);
}
- 实现服务接口:
@DubboService(version = "1.0.0")
public class GreetingServiceImpl implements GreetingService {
@Override
public String sayHello(String name) {
return "Hello, " + name + "!";
}
}
- 在Spring Boot启动类上添加
@EnableDubbo
注解:
@SpringBootApplication
@EnableDubbo
public class DubboProviderApplication {
public static void main(String[] args) {
SpringApplication.run(DubboProviderApplication.class, args);
}
}
以上代码展示了如何在Spring Boot应用中配置和启动一个Dubbo服务提供者,它使用ZooKeeper作为注册中心。这个例子非常基础,但它提供了整合Dubbo和ZooKeeper所需的核心步骤。
