Interface BindingErrorProcessor

All Known Implementing Classes:
DefaultBindingErrorProcessor
public interface BindingErrorProcessor
Strategy for processing DataBinder's missing field errors, and for translating a PropertyAccessException to a FieldError.

The error processor is pluggable so you can treat errors differently if you want to. A default implementation is provided for typical needs.

Note: As of Spring 2.0, this interface operates on a given BindingResult, to be compatible with any binding strategy (bean property, direct field access, etc). It can still receive a BindException as argument (since a BindException implements the BindingResult interface as well) but no longer operates on it directly.

Since:
1.2

    • processMissingFieldError

      void processMissingFieldError(String missingField, BindingResult bindingResult)
      Apply the missing field error to the given BindException.

      Usually, a field error is created for a missing required field.

      Parameters:
      missingField - the field that was missing during binding
      bindingResult - the errors object to add the error(s) to. You can add more than just one error or maybe even ignore it. The BindingResult object features convenience utils such as a resolveMessageCodes method to resolve an error code.

    • processPropertyAccessException

      void processPropertyAccessException(PropertyAccessException ex, BindingResult bindingResult)
      Translate the given PropertyAccessException to an appropriate error registered on the given Errors instance.

      Note that two error types are available: FieldError and ObjectError. Usually, field errors are created, but in certain situations one might want to create a global ObjectError instead.

      Parameters:
      ex - the PropertyAccessException to translate
      bindingResult - the errors object to add the error(s) to. You can add more than just one error or maybe even ignore it. The BindingResult object features convenience utils such as a resolveMessageCodes method to resolve an error code.
