方法详细资料

• invokeValidator

  public static void invokeValidator​(Validator validator,
                                     Object obj,
                                     Errors errors)

  Invoke the given Validator for the supplied object and Errors instance.

  参数:

  validator - the Validator to be invoked (must not be null)

  obj - the object to bind the parameters to

  errors - the Errors instance that should store the errors (must not be null)

  抛出:

  IllegalArgumentException - if either of the Validator or Errors arguments is null, or if the supplied Validator does not support the validation of the supplied object's type

• invokeValidator

  public static void invokeValidator​(Validator validator,
                                     Object obj,
                                     Errors errors,
                                     Object... validationHints)

  Invoke the given Validator/SmartValidator for the supplied object and Errors instance.

  参数:

  validator - the Validator to be invoked (must not be null)

  obj - the object to bind the parameters to

  errors - the Errors instance that should store the errors (must not be null)

  validationHints - one or more hint objects to be passed to the validation engine

  抛出:

  IllegalArgumentException - if either of the Validator or Errors arguments is null, or if the supplied Validator does not support the validation of the supplied object's type

• rejectIfEmpty

  public static void rejectIfEmpty​(Errors errors,
                                   String field,
                                   String errorCode)

  Reject the given field with the given error code if the value is empty.

  An 'empty' value in this context means either null or the empty string "".

  The object whose field is being validated does not need to be passed in because the Errors instance can resolve field values by itself (it will usually hold an internal reference to the target object).

  参数:

  errors - the Errors instance to register errors on

  field - the field name to check

  errorCode - the error code, interpretable as message key

• rejectIfEmpty

  public static void rejectIfEmpty​(Errors errors,
                                   String field,
                                   String errorCode,
                                   String defaultMessage)

  Reject the given field with the given error code and default message if the value is empty.

  An 'empty' value in this context means either null or the empty string "".

  The object whose field is being validated does not need to be passed in because the Errors instance can resolve field values by itself (it will usually hold an internal reference to the target object).

  参数:

  errors - the Errors instance to register errors on

  field - the field name to check

  errorCode - error code, interpretable as message key

  defaultMessage - fallback default message

• rejectIfEmpty

  public static void rejectIfEmpty​(Errors errors,
                                   String field,
                                   String errorCode,
                                   Object[] errorArgs)

  Reject the given field with the given error code and error arguments if the value is empty.

  An 'empty' value in this context means either null or the empty string "".

  The object whose field is being validated does not need to be passed in because the Errors instance can resolve field values by itself (it will usually hold an internal reference to the target object).

  参数:

  errors - the Errors instance to register errors on

  field - the field name to check

  errorCode - the error code, interpretable as message key

  errorArgs - the error arguments, for argument binding via MessageFormat (can be null)

• rejectIfEmpty

  public static void rejectIfEmpty​(Errors errors,
                                   String field,

                                   String defaultMessage)

  Reject the given field with the given error code, error arguments and default message if the value is empty.
