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: 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.

方法详细资料

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(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.
