Enough explanation; it's time to get our hands dirty with actual code. In this section, we will create a movie catalog site with integrated Spring Security. We will be using reactive concepts throughout and will use form-based login. We will start with hardcoded users and then see how we can look at a persistent user store to authenticate the users against. We will then into testing in more detail and finally look at some customizations that we can bring to Spring Security pages. Finally, we will touch base on authorization aspects and close the sample application.
