## 接口 BindingErrorProcessor

- 所有已知实现类:
    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.

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

    - #### 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.

      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

          void processPropertyAccessException(org.springframework.beans.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.

      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.
