public class ExceptionHandlers
extends java.lang.Object
A set of exception handlers is configured by defining ExceptionHandlersConfiguration
beans
in spring.xml. If a project needs specific handlers, it should define a bean of such type with its own
id, e.g. refapp_ExceptionHandlersConfiguration
An instance of this class is bound to App
.
