Class DefaultBindingErrorProcessor

java.lang.Object
  org.springframework.validation.DefaultBindingErrorProcessor

All Implemented Interfaces:

BindingErrorProcessor

public class DefaultBindingErrorProcessor
extends Object
implements BindingErrorProcessor

Default BindingErrorProcessor implementation.

Uses the "required" error code and the field name to resolve message codes for a missing field error.

Creates a FieldError for each PropertyAccessException given, using the PropertyAccessException's error code ("typeMismatch", "methodInvocation") for resolving message codes.

1.2

Method Detail

processMissingFieldError

public void processMissingFieldError(String missingField,
                                     BindException errors)

Description copied from interface: BindingErrorProcessor

Apply the missing field error to the given BindException.

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

Specified by:

processMissingFieldError in interface BindingErrorProcessor

Parameters:

missingField - the field that was missing during binding

errors - the errors object to add the error(s) to. You can add more than just one error or maybe even ignore it.

See Also:

BindException.addError(org.springframework.validation.ObjectError), BindException.resolveMessageCodes(java.lang.String)

processPropertyAccessException

public void processPropertyAccessException(PropertyAccessException ex,
                                           BindException errors)

Description copied from interface: BindingErrorProcessor

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.

Specified by:

processPropertyAccessException in interface BindingErrorProcessor

Parameters:

ex - the PropertyAccessException to translate

errors - the errors object to add the error(s) to. You can add more than just one error or maybe even ignore it. The BindException object features convenience utils such as a MessageCodesResolver to resolve an error code into message codes.

Errors, FieldError, ObjectError, MessageCodesResolver, BindException.addError(org.springframework.validation.ObjectError), BindException.resolveMessageCodes(java.lang.String)

getArgumentsForBindError

protected Object[] getArgumentsForBindError(String objectName,
                                            String field)

Return FieldError arguments for a binding error on the given field. Invoked for each missing required fields and each type mismatch.

Default implementation returns a DefaultMessageSourceResolvable with "objectName.field" and "field" as codes.

Parameters:

field - the field that caused the binding error

Returns:

the Object array that represents the FieldError arguments
