title: Activating account after registering to a web application
body: <p>Basically, I am developing a web application based on the Spring Framework where I would like users to confirm their initial registration with an email, which gets sent out to them once they register with the application. They cannot login until they confirm that email.
  Could someone help with a tutorial or something? I am new to implementing this sought of feature. </p>
  
  <p>Thanks</p>
