Spring Config Client Project

This project is a Spring Config Client that connects to a Config Server to fetch its configuration. The client is set up to refresh its configuration every 60 seconds.

Project Setup

This project is built using Java 21, Spring Boot 3.2.4, Spring Cloud 2023.0.0, and Maven.

Dependencies

The project uses the following dependencies:

• Spring Boot Starter Actuator
• Spring Cloud Starter
• Spring Cloud Starter Config
• Lombok
• Spring Boot Starter Test
• Spring Boot Starter Web

Configuration Refresh

The Config Client is set up to automatically refresh its configuration from the Config Server every 60 seconds. This is achieved by using the @RefreshScope annotation on the beans that need to be refreshed, and setting up a scheduled task that calls the /actuator/refresh endpoint every 60 seconds.

Here is an example of how to use the @RefreshScope annotation:

@RefreshScope
@RestController
@RequestMapping("/data")
public class ValueController {

  @Value("${rest.application.environment:#{null}}")
  public String environment;

  @GetMapping("/")
  public Map<String, String> getProperties() {
    return Map.of("environment", environment);
  }

}

In the above example, the rest.application.environment value will be refreshed every 60 seconds.
Running the Project To run the project, use the following command: mvn spring-boot:run

This will start the Config Client, which will connect to the Config Server and fetch the configuration. The configuration will be refreshed every 60 seconds.

Please replace rest.application.environment and ValueController with your actual property and controller names.
