JRebel Spring plugin helps by remembering all Spring’s XML files on startup and listening for changes to those files at runtime. If any files are changed, the plugin triggers a reinitialization of Spring framework’s configuration, making sure that updates to bean configuration take effect. Similar integration plugins exist for the vast majority of popular Java frameworks. These are shipped within the JRebel Agent. When your application is based on a public framework stack (like most Java applications), you should never need to write a JRebel plugin. However, when using proprietary, home-grown or in-house Java frameworks, chances are that the built-in integration does not exist for some of your reloading scenarios. Sample application with a sample plugin ¶ If that is the case, this guide will help you with writing a custom JRebel plugin to solve those issues. This section will explain the JRebel SDK using a simple web application and a sample plugin that reloads the web application changes. The web application monitors free system memory by polling the value of Runtime.getRuntime().freeMemory(). The application has a configuration class that specifies the polling rate and the amount of samples to store. #Jrebel license file free#Ī GET request to the servlet will return the current timestamp and the average free memory based on the collected samples.How JRebel can speed up your Java application development The data is published using a plain Java servlet.
JRebel is a productivity tool that allows developers to reload code changes instantly. It skips the rebuild, restart and redeploy cycle common in Java development. JRebel enables developers to get more done in the same amount of time and to stay in the flow while coding.

What is even better, JRebel supports the majority of real-world enterprise Java stacks and is easy to install into your development environment.
When dealing with Java application development, you go through several actions over and over again.
