• reject

  public void reject​(String errorCode,
                     @Nullable
                     Object[] errorArgs,
                     @Nullable
                     String defaultMessage)

  从接口复制的说明: Errors
  Register a global error for the entire target object, using the given error description.

  指定者:

  reject 在接口中 Errors

  参数:

  errorCode - error code, interpretable as a message key

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

  defaultMessage - fallback default message

• rejectValue

  public void rejectValue​(@Nullable
                          String field,

  Register a field error for the specified field of the current object (respecting the current nested path, if any), using the given error description.

  The field name may be null or empty String to indicate the current object itself rather than a field of it. This may result in a corresponding field error within the nested object graph or a global error if the current object is the top object.

  覆盖:

  getFieldType 在类中 AbstractErrors

  参数:

  field - the field name

  返回:

  the type of the field, or null if not determinable

• getModel

  public Map<String,​Object> getModel()

  Return a model Map for the obtained state, exposing an Errors instance as 'MODEL_KEY_PREFIX + objectName' and the object itself.

  Note that the Map is constructed every time you're calling this method. Adding things to the map and then re-calling this method will not work.

  The attributes in the model Map returned by this method are usually included in the ModelAndView for a form view that uses Spring's bind tag, which needs access to the Errors instance.
