Tracking HTTP Method Calls in Your REST API

In today's guide, we're going to address a common challenge faced by developers working with REST APIs: how to count the number of HTTP method calls and store that information in a database. This is particularly useful if you're trying to monitor usage patterns or ensure your services are running as expected.

In this example, we will focus on a Java application using MySQL as our database. The scenario involves a method that retrieves user information from GitHub's API and counts how many times this method has been called through HTTP requests.

Introduction to the Problem

The Scenario

You have a simple REST API set up with a request mapping to retrieve user information. However, you have encountered an issue where the database isn't updated correctly when your endpoint is called. Specifically, the method for inserting or updating user login counts isn't functioning as expected.

The Existing Code

You have a REST controller with a GET method that looks something like this:

The intention is for the insertRecord method to either update the count for existing user logins or create a new entry in the database.

Understanding the Solution

Issues Found in the Code

The primary reason why the insertRecord method is failing to update or insert records in your database can be traced back to a missing step. In your current implementation, although you prepare your SQL statements, you are not executing the updates.

Key Solution Strategy

The solution is straightforward: you need to call the executeUpdate() method on your prepared statements. This finalizes your database operations and ensures any changes you configure are applied. Here’s how you can revise your insertRecord method:

Summary of Changes

Added executeUpdate() Calls: Ensure that the executeUpdate() method is called for both insert and update prepared statements.

Error Logging: Enhanced error logging to provide more clarity on specific failures.

Conclusion

By following the solutions outlined in this guide, you can effectively count HTTP method calls in your REST API and store the data in your database. Be sure to test your revised insertRecord method to confirm that it updates and inserts records correctly.

Tracking API usage can provide valuable insights and help ensure that your application runs smoothly. Implement these changes and enjoy the improved functionality of your REST API!

Happy coding!
