Interface HandlerExceptionResolver

  • All Known Implementing Classes:
    AbstractHandlerExceptionResolver, AnnotationMethodHandlerExceptionResolver, SimpleMappingExceptionResolver
    public interface HandlerExceptionResolver
    Interface to be implemented by objects than 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 the error page JSPs, but can be used with any kind of exception including any checked exception, with potentially fine-granular mappings for specific handlers.
