		done). The equivalent Java Configuration is in the ExceptionConfiguration 
		class -->

	<!-- The use of the "xml-config" profile here is for demonstration only. 
		A real application wouldn't normally need to switch between XML or Java Configuration. 
		You would use one, or other, or both, all the time. -->

			ExampleSimpleMappingExceptionResolver and see the difference when /unhandledException

			<!-- Normally Spring MVC has no default error view and this class is the 
				only way to define one. A nice feature of Spring Boot is the ability to provide 
				a very basic default error view (otherwise the application server typically 
				returns a Java stack trace which is not acceptable in production). See Blog 
				for more details. -->

			<!-- To stick with the Spring Boot approach, DO NOT set this property 
				of SimpleMappingExceptionResolver. -->

			<!-- Here we are choosing to use SimpleMappingExceptionResolver since 
				many Spring applications have used the approach since Spring V1. Normally 
				we would specify the view as "error" to match Spring Boot, however so you 
				can see what is happening, we are using a different page. -->
