DefaultBindingErrorProcessor

extends Object
implements BindingErrorProcessor

Class Overview

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.

Constants

public static final String MISSING_FIELD_ERROR_CODE

Error code that a missing field error (i.e. a required field not found in the list of property values) will be registered with: "required".

Constant Value: "required"

Public Constructors

public DefaultBindingErrorProcessor ()

Public Methods

public 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.

public 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.

Protected Methods

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

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

The default implementation returns a single argument indicating the field name (of type DefaultMessageSourceResolvable, with "objectName.field" and "field" as codes).

Parameters
objectName the name of the target object
field the field that caused the binding error
Returns
  • the Object array that represents the FieldError arguments
