Let's start writing some Spring apps! But first, enjoy this gif of a drunk guy trying to use an ATM:

Gets me every time. Now, on to our assignment.

Make a web application that allows you write and delete short messages. When you click "Submit", it will refresh and show a list of messages you wrote. If you're feeling déjà vu, it's because this is the same assignment we did two weeks ago, but this time we're doing it with Spring.

• Create home.html in the templates directory
  • It should display a login form like the first screenshot
• Create a controller class next to the main application class
• In your controller, create a route for /
  • It should take the model and the request as arguments
  • It should read the username from the session and add it to the model
  • It should return the home template
• In your controller, create a route for /login
  • It should take the request and the username as arguments
  • It should save the username to the session
  • It should return a redirect to /
• In home.html, use Mustache tags to conditionally show the markup in the two screenshots below
  • If username doesn't exist, show the login form like the first screenshot
  • If username does exist, show the message submission form and message list like the second screenshot
• Create a Message class next to your other classes
  • It should have fields for id and text
• Create an ArrayList<Message> in your controller to store submitted messages
• In your controller, create a route for /add-message
  • It should take the message text as an argument
  • It should create a Message object and add it to the arraylist (for the id, do something like messages.size() + 1)
  • It should return a redirect to /
• In home.html, add a button or link called "Delete" next to each message
  • It will need to send the id as a parameter
• In your controller, create a route for /delete-message
  • It should take the message id as an argument
  • It should remove the message with the given id (do something like messages.remove(id - 1))
  • It should return a redirect to /
