Introduction

In modern web applications developed using Spring Boot, actuators play a significant role in monitoring and managing your application. One common question among developers is whether it is possible to create more than one GET custom actuator endpoint. This guide will walk you through the steps necessary to create multiple custom actuator endpoints, specifically focusing on how to implement URLs like /actuator/features/active and /actuator/features/status.

Understanding the Need for Multiple Endpoints

Creating multiple custom actuator endpoints provides you with the flexibility to expose various features of your application. For instance, in our case, we want to check if certain features are active and get their status, which can aid in debugging and monitoring.

Step-by-Step Guide to Create Custom Actuator Endpoints

1. Define Your Custom Endpoints

To create custom actuator endpoints, we can leverage @ RestController along with Spring’s mapping annotations. Here's how you can define your endpoints to return specific responses for feature checks.

Example Implementation:

You will want to define a new class for your endpoint that uses the @ RestController annotation. Here’s how it can look:

2. Explanation of the Code

Let's break down the provided code so you can understand exactly how each part works:

@ RestController: This annotation indicates that the class is a controller that handles incoming HTTP requests, effectively making it a RESTful web service.

@ RequestMapping("/actuator/features"): This specifies the base path for the endpoints. All requests to /actuator/features will be managed by this class.

@ GetMapping("/active"): This annotation maps HTTP GET requests onto the isActive() method, making it accessible via the /active path.

@ GetMapping("/status"): Similar to the above, this maps GET requests to the getStatus() method, which can be accessed via the /status path.

Return Value: Both methods return a boolean value (in this case, true), but they could be enhanced to perform more substantial checks depending on your application’s needs.

3. Testing Your Custom Endpoints

After implementing the code, you can test your endpoints by running your Spring Boot application and accessing the following URLs in your web browser or a tool like Postman:

http://localhost:8080/actuator/features/active should return true

http://localhost:8080/actuator/features/status should also return true

Conclusion

Creating multiple GET custom actuator endpoints in Spring Boot is straightforward and can greatly enhance your application's monitoring capabilities. By defining your endpoints similarly to the method we described, you’ll not only be able to improve your application management but also tailor it according to your specific monitoring needs.

By following the steps outlined in this guide, you should now have a solid understanding of how to implement multiple actuator endpoints effectively. Happy coding!
