SpringCloud @EnableDiscoveryClient Anotasyonu

Giriş

Açıklaması şöyle

@EnableDiscoveryClient which comes from spring-cloud-commons is the same as @EnableEurekaClient but it is a more generic implementation of “Discovery Service”.

@EnableEurekaClient only works with Eureka whereas @EnableDiscoveryClient works with eureka, consul, zookeeper. But if Eureka is on the application classpath, they are effectively the same.

Örnek

Şöyle yaparız

@Configuration
@EnableZookeeper
public class ZooKeeperConfiguration extends ZookeeperProperties {
    public ZooKeeperConfiguration() {
        setConnectString("localhost:2181");
        setBaseSleepTimeMs(1000);
        setMaxRetries(3);
        setSessionTimeoutMs(5000);
    }
}

@Service
public class MyService {
  @Autowired
  private ZooKeeperClient zooKeeperClient;

  public List<String> getNodes(String path) throws KeeperException, InterruptedException {
    return zooKeeperClient.getChildren(path);
  }
}

Açıklaması şöyle

Next, you’ll need to configure the connection to your ZooKeeper server. You can do this by creating a ZooKeeperConfiguration class that extends org.springframework.cloud.zookeeper.ZookeeperProperties and sets the connection properties, like so:

This sets the connection string to localhost:2181 and configures some other properties for the connection.

Finally, you can use the ZooKeeper client in your Spring Boot application by autowiring a ZooKeeperClient instance.
