@Bean open fun handlerExceptionResolver(): HandlerExceptionResolver
Returns a HandlerExceptionResolverComposite containing a list of exception resolvers obtained either through #configureHandlerExceptionResolvers(List) or through #addDefaultHandlerExceptionResolvers(List).
Note: This method cannot be made final due to CGLib constraints. Rather than overriding it, consider overriding #configureHandlerExceptionResolvers(List), which allows providing a list of resolvers.
