Sometime back I’ve written a tutorial on Hello World Spring MVC. Spring MVC web is a model-view-control framework and you can find more information here.
As you could see Sayan and Arturo asked few questions while working on Spring MVC tutorial on how to add JavaScript/.js and CSS/.css file to their project.
Both .js and .css are static resources. Do you also have similar question like:
- In spring mvc where to put css/js/img files?
- Why my project can’t find css, images and js static files, etc?
In this tutorial we will go over all detailed steps on how to include both into your Spring MVC java project simplest way.
Let’s get started:
Below is an updated project structure for your reference.
Step-1
Please go ahead and implement your HelloWorld Spring MVC project by following all detailed steps. Make sure you have it working correctly.
Now, in below steps we are going to – create 1 folder, add 2 files, modify 2 files.
