Reloading Changes in Spring Boot: No Server Restart Required!

SUBSCRIBE TO RAM N JAVAThe Problem: Constant Restarts
Are you tired of stopping and starting your Spring Boot server every time you make a tiny code change? It’s a major productivity killer! Waiting for the JVM to spin up repeatedly can add hours of wasted time to your development week. In this guide, we’ll show you how to eliminate those restarts and see your changes instantly.
Enter Spring Boot DevTools
The secret weapon is Spring Boot DevTools. This module is designed specifically to improve the development experience. Its most famous feature is Automatic Restart. Whenever a file on your classpath changes, DevTools detects the change and triggers a fast restart of the application context.
Why is it Faster?
DevTools uses a "two-classloader" strategy. One classloader handles the libraries that don't change (like the Spring framework itself), and another handles your project classes. When you make a change, only the project classloader is restarted, making the process significantly faster than a full cold start.
How to Enable It
Just add the following dependency to your pom.xml file, and Spring Boot takes care of the rest:
