Spring boot devtools - Static content reloading does not work in IntelliJ

For Windows users the steps are:
1) Go to File->Settings, then to "Build,Execution,Deployment"->Compiler and enable the "Make project automatically" flag.
2) Press Ctrl-Alt-Shift-/ and select "Registry" from the menu that appears. Enable compiler.automake.allow.when.app.running flag.
3) Start/restart the app and observe static content reloading.

You need to turn on a couple of features in IntelliJ to make this work.

First, there's a project specific setting which you would need to apply on any project you want to use devtools in. Go to Preferences > Compiler and enable "Make project automatically."

The next setting is an IDEA registry setting that applies to all projects.

• In macOS (OSX), press Shift+Command+A (Shift+Ctrl+A in Windows)
• Type "Registry" in the search box that appears, and select the registry to open it.
• Lookup compiler.automake.allow.when.app.running and enable it.

After that, restart your app. You will notice that the project keeps rebuilding with every change you make. When you check out the result in the browser, you will see both static files and code have been updated.

For IntelliJ 2021.2 version or above below are steps that you need to follow

1. Add spring-boot-devtools dependency if not already added.

2. Enable Build project automatically as shown below

3. Enable option in Advanced Settings as shown below
