Create Custom SpringBoot Banners & Activate JetBrains Agent in IDEA
This guide shows how to add a custom SpringBoot startup banner via a banner.txt file, lists online ASCII art generators for creating text banners, and provides step‑by‑step instructions to install and activate the JetBrains agent in IntelliJ IDEA for license management.
1. Custom SpringBoot Banner (banner.txt)
In a SpringBoot project, create a banner.txt file in the resources directory, paste the desired startup banner text, and the banner will appear when the application starts.
2. Online ASCII Banner Generators
Several websites can generate ASCII art banners from text or images:
patorjk.com/software/taag/ – supports various fonts such as “Big” and “Doom”.
bootschool.net/ascii
network-science.de/ascii/
degraeve.com/img2txt.php – converts images to text.
3. Activate JetBrains Agent in IntelliJ IDEA
Steps to activate the JetBrains license agent:
Copy jetbrains-agent.jar to the bin directory of IntelliJ IDEA.
Open Help → Edit Custom VM Options and add a line such as -javaagent:/path/to/jetbrains-agent.jar (replace with the actual absolute path).
Restart IDEA, choose License Server and set the server URL to http://fls.jetbrains-agent.com.
-javaagent:/Applications/IntelliJ IDEA.app/Contents/bin/jetbrains-agent.jar
