Spring Cloud Etcd

Etcd integration with Spring Cloud, based on etcd v3 api(jetcd).

Feature

• Jetcd Starter Supports
• Spring Cloud Discovery Client and Service Registry(like Spring Cloud Consul)

Example

uses with Spring Cloud Feign:

Add dependencies:

<dependencies>
    <dependency>
        <groupId>com.scienjus</groupId>
        <artifactId>spring-cloud-etcd-discovery</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>1.5.4.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-feign</artifactId>
        <version>1.3.1.RELEASE</version>
    </dependency>
</dependencies>

Create Spring MVC service project:

@RestController
@SpringBootApplication
public class App {

  @GetMapping("hello")
  public String hello() {
    return "world";
  }

  public static void main(String[] args) {
    SpringApplication.run(App.class, args);
  }
}

Configure etcd properties:

spring:
  cloud:
    etcd:
      endpoints: http://127.0.0.1:2379
      discovery:
        prefix: /services

After server started up, check service-registry by etcdctl:

-> % ETCDCTL_API=3 etcdctl get /services --prefix
/services/application/192.168.1.102:8080
{"serviceName":"application","address":"192.168.1.102","port":8080,"serviceId":"application"}

Then you can use Feign Client like Spring Cloud Consul.
