Studio: Skills Tracker

Wouldn’t it be nice to have a small tracker to show us what skills we have built and where we are at in learning them? Let’s build something that would let us do just that!

As always, read through the whole studio before starting!

At the end of the studio, your final project should be able to take input from a user via a form and post the information in a way that is easy to read.

Start up Spring

Using the Spring Initializr

Head to the Spring initializr to initialize a new Spring project.

  1. For Project, select Gradle Project, for Language, select Java, and for Spring Boot, select 3.1.x (whichever is the most recent release, that is NOT a snapshot).
  2. For Project Metadata, we can use org.launchcode as Group and skills-tracker as the artifact.
  3. Finally, we want to add Spring Web and Spring Boot DevTools as our dependencies.

Once the above has been accomplished your spring initializr should look similar to the following screenshot:

Spring Initializr page with correct options for skills-tracker studio

Double check that everything is ready to go and click Generate!

Launching IntelliJ

Unzip the newly generated and move the folder into the directory where you are keeping your homework for this class!

Open IntelliJ and select Import Project. Double click bootRun and head to localhost:8080 to make sure there is nothing there.

Now you are ready to start coding!

Creating Controllers

In your org.launchcode package, add another package called controllers and add a class called SkillsController. Inside SkillsController, you will add several methods to accomplish the following:

  1. At localhost:8080, add text that states the three possible programming languages someone could be working on. You need to have an h1 with the title “Skills Tracker”, an h2, and an ol containing three programming languages of your choosing.
  2. At localhost:8080/form, add a form that lets the user enter their name and choose their favorite, second favorite, and third favorite programming languages on your list. Use select elements for each of the rankings. Just as with the exercises, we will use @GetMapping().
  3. Also at localhost:8080/form, use @PostMapping and @RequestParam to update the HTML with an h1 stating the user’s name and an ol showing the three programming languages in the order they chose.

End Result

At the end of the studio, when you navigate to localhost:8080, you should see the following:

When you navigate to localhost:8080/form, you should see a blank form that looks something like:

If you fill out the form, your page may render like so:

Bonus Missions

  1. Reformat your form page to use a table instead of an ordered list.
  2. Add a new path to the site to display the information from the completed form.
