What is Spring Boot DevTools?

Answer»

Spring Boot provides ‘spring-boot-devtools’ module with features that help the programmers while developing the application. It basically improves the experience of developing a Spring Boot application. One of the key features is AUTOMATIC reload of application as soon as there is a change; hence developer does not NEED to STOP and start the application each time. The is an intelligent feature as it only reloads the actively developed classes but not the third-party JARs.

Another key feature is that by def,ault it disables the caching of view templates and static files. This enables a developer to see the changes as soon as they make them.

In CASE, we want to DISABLE any of these features, then we need to set them in an application.yml file. For example -Dspring.devtools.restart.enabled=false will avoid automatic application restart.

Below are a few of the features provided:

  1. Property defaults
  2. Automatic Restart
  3. Live Reload
  4. Global settings
  5. Remote applications
