• Nothing.

• This is not a controller class declaration, but a special type of bean used for handling exceptions thrown by handler methods.

• The handle() method is not allowed to return an instance of ModelAndView

• The handler method should be annotated with @RequestMapping or one of its specializations.

• Declare a local integer property and annotate it with @LocalServerPort

• Declare a local integer property and annotate it with @TestServerPort

• Make the test class extend SpringBootWebTest and call the getLocalServerPort()
