方法详细资料

• addAttribute

  Model addAttribute​(String attributeName,
                     Object attributeValue)

  Add the supplied attribute under the supplied name.

  参数:

  attributeName - the name of the model attribute (never null)

  attributeValue - the model attribute value (can be null)

• addAttribute

  Model addAttribute​(Object attributeValue)

  Add the supplied attribute to this Map using a generated name.

  Note: Empty Collections are not added to the model when using this method because we cannot correctly determine the true convention name. View code should check for null rather than for empty collections as is already done by JSTL tags.
