      public MessageCodesResolver getMessageCodesResolver()
      Return the strategy to use for resolving errors into message codes.

    • 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:

    • 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 Framework's bind tag, which needs access to the Errors instance.
