• supports

  public boolean supports​(Class<?> clazz)

  从接口复制的说明: Validator
  Can this Validatorvalidate instances of the supplied clazz?

  This method is typically implemented like so:

  return Foo.class.isAssignableFrom(clazz);

  (Where Foo is the class (or superclass) of the actual object instance that is to be validated.)

  指定者:

  supports 在接口中 Validator

  参数:

  clazz - the Class that this Validator is being asked if it can validate

  返回:

  true if this Validator can indeed validate instances of the supplied clazz

• validate

  public void validate​(Object target,
                       Errors errors)

  从接口复制的说明: Validator
  Validate the supplied target object, which must be of a Class for which the Validator.supports(Class) method typically has (or would) return true.

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

  指定者:

  validate 在接口中 Validator

  参数:

  target - the object that is to be validated (can be null)

  errors - contextual state about the validation process (never null)

• validate

  public void validate​(Object target,
                       Errors errors,
                       Object... validationHints)

  从接口复制的说明: SmartValidator
  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.

  指定者:

  validate 在接口中 SmartValidator

  参数:

  target - the object that is to be validated (can be null)

  errors - contextual state about the validation process (never null)

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

• processConstraintViolations

  protected void processConstraintViolations​(Set<ConstraintViolation<Object>> violations,
                                             Errors errors)

  Process the given JSR-303 ConstraintViolations, adding corresponding errors to the provided Spring Errors object.

  参数:

  violations - the JSR-303 ConstraintViolation results

  errors - the Spring errors object to register to

• determineField

  protected String determineField​(ConstraintViolation<Object> violation)

  Determine a field for the given constraint violation.

  The default implementation returns the stringified property path.

  参数:

  violation - the current JSR-303 ConstraintViolation

  返回:

  the Spring-reported field (for use with Errors)

  从以下版本开始:

  4.2

• determineErrorCode

  protected String determineErrorCode​(ConstraintDescriptor<?> descriptor)

  Determine a Spring-reported error code for the given constraint descriptor.

  The default implementation returns the simple class name of the descriptor's annotation type. Note that the configured MessageCodesResolver will automatically generate error code variations which include the object name and the field name.

  参数:

  descriptor - the JSR-303 ConstraintDescriptor for the current violation

  返回:

  a corresponding error code (for use with Errors)

  从以下版本开始:

  4.2

• getArgumentsForConstraint

  protected Object[] getArgumentsForConstraint​(String objectName,
                                               String field,
                                               ConstraintDescriptor<?> descriptor)

  Return FieldError arguments for a validation error on the given field. Invoked for each violated constraint.

  The default implementation returns a first argument indicating the field name (see getResolvableField(java.lang.String, java.lang.String)). Afterwards, it adds all actual constraint annotation attributes (i.e. excluding "message", "groups" and "payload") in alphabetical order of their attribute names.

  Can be overridden to e.g. add further attributes from the constraint descriptor.

  参数:

  objectName - the name of the target object

  field - the field that caused the binding error

  descriptor - the JSR-303 constraint descriptor

  返回:

  the Object array that represents the FieldError arguments

• getResolvableField

  protected MessageSourceResolvable getResolvableField​(String objectName,
                                                       String field)

  Build a resolvable wrapper for the specified field, allowing to resolve the field's name in a MessageSource.

  The default implementation returns a first argument indicating the field: of type DefaultMessageSourceResolvable, with "objectName.field" and "field" as codes, and with the plain field name as default message.

  参数:

  objectName - the name of the target object

  field - the field that caused the binding error

  返回:

  a corresponding MessageSourceResolvable for the specified field

  从以下版本开始:

• getRejectedValue

  protected Object getRejectedValue​(String field,
                                    ConstraintViolation<Object> violation,
                                    BindingResult bindingResult)

  Extract the rejected value behind the given constraint violation, for exposure through the Spring errors representation.

  参数:

  field - the field that caused the binding error

  violation - the corresponding JSR-303 ConstraintViolation

  bindingResult - a Spring BindingResult for the backing object which contains the current field's value

  返回:

  the invalid value to expose as part of the field error
