Creating an Apex Server-Side Controller

Use the Developer Console to create an Apex server-side controller.
  1. Open the Developer Console.
  2. Click File | New | Apex Class.
  3. Enter a name for your server-side controller.
  4. Click OK.
  5. Enter a method for each server-side action in the body of the class.

    Add the @AuraEnabled annotation to any methods, including getters and setters, that you wish to expose on the client- or server-side. This means that you only expose methods that you have explicitly annotated.

    Note

  6. Click File | Save.
  7. Open the component that you want to wire to the new controller class.
  8. Add a controller system attribute to the <aura:component> tag to wire the component to the controller. For example: 
    1<aura:component controller="SimpleServerSideController" >
