Spring web application - what design patterns should I use?

I have been given the task to create a web application using as many design patterns as possible. The web app must be a catalogue for a book store and contain basic CRUD operations.

I am new to design patterns so I wouldn't be the best at them. I will be using Spring so I will have controllers, services and then DAOs. From my understanding of them, DAO implementations use the facade pattern.

Could anyone explain them a little better or recommend some that I could use?
