public interface HandlerExceptionResolver
Interface to be implemented by objects that can resolve exceptions thrown during handler mapping or execution, in the typical case to error views. Implementors are typically registered as beans in the application context.Error views are analogous to JSP error pages but can be used with any kind of exception including any checked exception, with potentially fine-grained mappings for specific handlers.
