    Validate the supplied target object, which must be of a type of Class for which the Validator.supports(Class) method typically returns true.
    default void
    validateValue(Class<?> targetType, String fieldName, Object value, Errors errors, Object... validationHints)
    Validate the supplied value for the specified field on the target type, reporting the same validation errors as if the value would be bound to the field on an instance of the target class.

    • validate

      void validate(Object target, Errors errors, Object... validationHints)
      Validate the supplied target object, which must be of a type of Class for which the Validator.supports(Class) method typically returns true.

      The supplied errors instance can be used to report any resulting validation errors.

      This variant of validate() supports validation hints, such as validation groups against a JSR-303 provider (in which case, the provided hint objects need to be annotation arguments of type Class).

      Note: Validation hints may get ignored by the actual target Validator, in which case this method should behave just like its regular Validator.validate(Object, Errors) sibling.

      Parameters:
      target - the object that is to be validated
      errors - contextual state about the validation process
      validationHints - one or more hint objects to be passed to the validation engine

    • validateValue

      default void validateValue(Class<?> targetType, String fieldName, @Nullable Object value, Errors errors, Object... validationHints)
      Validate the supplied value for the specified field on the target type, reporting the same validation errors as if the value would be bound to the field on an instance of the target class.
      Parameters:
      targetType - the target type
      fieldName - the name of the field
      value - the candidate value
      errors - contextual state about the validation process
      validationHints - one or more hint objects to be passed to the validation engine
