How to Build Lightweight Service Discovery & Config with Govern Service and Redis

Service Discovery

Maven dependency (add spring-cloud-starter-loadbalancer)

<dependency>
    <groupId>me.ahoo.govern</groupId>
    <artifactId>spring-cloud-starter-discovery</artifactId>
</dependency>

Service Provider

Provider interface

public class DemoController {

    @GetMapping("/get")
    public String demo() {
        return "hello provider";
    }
}

application.yml – specify Redis address

spring:
  cloud:
    govern:
      redis:
        mode: standalone
        url: redis://127.0.0.1:6379
  application:
    name: provider

Service Consumer

application.yml – specify Redis address

spring:
  cloud:
    govern:
      redis:
        mode: standalone
        url: redis://127.0.0.1:6379
  application:
    name: consumer

Interface call demonstration

public class DemoController {
    private final RestTemplate restTemplate;

    @GetMapping
    public String req() {
        String url = "http://provider/get";
        return restTemplate.getForEntity(url, String.class).getBody();
    }
}

Call Test

curl http://localhost:8090

hello world

Configuration Management

Maven dependency

<dependency>
  <groupId>me.ahoo.govern</groupId>
  <artifactId>spring-cloud-starter-config</artifactId>
</dependency>

application.yml configuration

spring:
  application:
    name: config
  cloud:
    govern:
      config:
        config-id: config.yml
      redis:
        mode: standalone
        url: redis://localhost:6379

Code injection of configuration key

@RefreshScope
public class DemoController {

    @Value("${config.key}")
    private String key;

    @GetMapping
    public String demo() {
        return key;
    }
}

Summary

The author uses Redis as a registration and configuration center, implementing Spring Cloud Commons‑based service discovery and configuration management; Govern Service’s source is concise and helpful for beginners studying Spring Cloud core design.

The author also built pig‑mesh , a full implementation of Spring Cloud abstractions (service discovery, configuration, load balancing, language heterogeneity) that can be studied alongside Govern Service.
