How to Configure SpringLoaded with Eclipse Dynamic Web Project

The article presents simple steps to use SpringLoaded framework to have your classes loaded onto the tomcat server without you having required to restart the server, while you are working with Eclipse Dynamic Web Project. The instructions below applies when you have installed Tomcat server and added the same to the eclipse.
Quick Introduction on SpringLoaded

SpringLoaded, a framework published by Spring.io, is a JVM agent for reloading class file changes whilst a JVM is running. It transforms classes at loadtime to make them amenable to later reloading. Read further on this github page. Personally, I have found it very useful as I do not have to build and restart servers for every small changes. In many ways, the framework does what is done by popular JRebel.

 

Why use SpringLoaded?
  1. Does not require you to stop and start server after making changes into one or more classes.
  2. In that way, it acts as a productivity booster as one spends significant time in stopping and starting the server if there are minor changes in the Java classes.

 

Steps to Configure SpringLoaded

Step 1: Download the SpringLoaded library from https://github.com/spring-projects/spring-loaded. This is the link of current 1.2 version of SpringLoaded.

Step 2:  Place following as JVM argument in “Run Configuration” as shown in the screenshot below.

-Djavaagent:D:\javalibs\springlibs\springloaded-1.2.0.RELEASE.jar
