How to use Thymeleaf to make only a simple Java app (without Spring)

I'm following the official Thymeleaf tutorial on its website and I'm currently on the section Executing the template engine.

From what I understood, I should already be able to run the app coded so far, but I absolutely don't see how to run it. There is no main(String[] args) method to run at all.

I tried searching for other tutorials but they all use Spring which is not what I'm looking for right now.

Anyone knows where I should insert a main(String[] args) method to run this Thymeleaf app and view my HTML template? I don't understand where the entry point is or should be.

I apologize in advance if this question sounds dumb and thanks for your future replies.

Edit:

Until now, when following the tutorial I wrote 3 Java files:

• GTVGApplication class
• IGTVGController interface
• HomeController class
• home.html template to be displayed

So I thought of writing a main method like so: Main class containing main(String[] args) method

But I don't see how to correctly instantiate the servletContext and I'm not even sure if everything will work out once this is done.

You can create your main method in any class that you created and then create Thymeleaf objects that you need. This might help
