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.

Field Detail

### MISSING_FIELD_ERROR_CODE

    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 Field Values

    public DefaultBindingErrorProcessor()

Method Detail

### processMissingFieldError

    public void processMissingFieldError(String missingField,
                                         BindingResult bindingResult)

  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
    `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.
  See Also:
    `AbstractBindingResult.addError(org.springframework.validation.ObjectError)`, `AbstractBindingResult.resolveMessageCodes(java.lang.String)`

### processPropertyAccessException

    public void processPropertyAccessException(PropertyAccessException ex,
                                               BindingResult bindingResult)

  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
    `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.
  See Also:
    `Errors`, `FieldError`, `ObjectError`, `MessageCodesResolver`, `AbstractBindingResult.addError(org.springframework.validation.ObjectError)`, `AbstractBindingResult.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 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
