Developing a Custom Spring Boot Banner===

When you run a Spring Boot application, you may have noticed a default banner message that appears on the console. This banner message displays information about the Spring Boot application, such as the version number and the main class. However, did you know that you can customize this banner message with your own custom design? In this article, I will show you how to develop a custom Spring Boot banner and customize the application startup message with your own banner.

Customize the Application Startup Message with Your Own Banner

To customize the application startup message with your own banner, follow these steps:

1. Create a new file called "banner.txt" in the "src/main/resources" directory of your Spring Boot project.
2. Add your custom banner design to the "banner.txt" file. You can use ASCII art or any other text design.
3. Save the "banner.txt" file.

Here is an example of a custom banner design:

========================================================
|                                                       |
|                  My Custom Spring Boot                |
|                                                       |
|                      Version 1.0                      |
|                                                       |
|                    Welcome to my App!                 |
|                                                       |
========================================================

4. Run your Spring Boot application, and you should see your custom banner message on the console.

Customizing the Banner Text Color

You can also customize the color of your banner text. To do this, add ANSI escape codes to the "banner.txt" file. For example, to make the text red, use the code "33[31m" at the beginning of the text and "33[0m" at the end of the text. Here is an example:

33[31m========================================================33[0m
33[31m|                                                       |33[0m
33[31m|                  My Custom Spring Boot                |33[0m
33[31m|                                                       |33[0m
33[31m|                      Version 1.0                      |33[0m
33[31m|                                                       |33[0m
33[31m|                    Welcome to my App!                 |33[0m
33[31m|                                                       |33[0m
33[31m========================================================33[0m

In this example, "33[31m" sets the text color to red, and "33[0m" resets the text color back to the default.

Customizing the Banner Image

If you prefer an image-based banner, you can use the "banner.image.location" property in your application.properties file to specify the location of your banner image. The image must be in PNG, JPG, or GIF format. Here is an example:

banner.image.location=classpath:my-banner.png

This will display the "my-banner.png" image as the banner message. You can also customize the banner image size with the "banner.image.width" and "banner.image.height" properties.
