## 类 DefaultBindingErrorProcessor

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

- 所有已实现的接口:
    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.

    - #### processMissingFieldError

          public void processMissingFieldError(String missingField,
                                               BindingResult bindingResult)

      从接口复制的说明: `BindingErrorProcessor`
      Apply the missing field error to the given BindException.

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

      指定者:
        `processMissingFieldError` 在接口中 `BindingErrorProcessor`
      参数:
        `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

          public void processPropertyAccessException(org.springframework.beans.PropertyAccessException ex,
                                                     BindingResult bindingResult)

      从接口复制的说明: `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.

      指定者:
        `processPropertyAccessException` 在接口中 `BindingErrorProcessor`
      参数:
        `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.

    - #### 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).

      参数:
        `objectName` - the name of the target object
        `field` - the field that caused the binding error
      返回:
        the Object array that represents the FieldError arguments
