类 DefaultBindingErrorProcessor

java.lang.Object

cn.taketoday.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.

从以下版本开始:

4.0

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(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
