public @interface ModelAttribute
@RequestMapping
methods.
Can be used to expose command objects to a web view, using
specific attribute names, through annotating corresponding
parameters of an @RequestMapping
method.
Can also be used to expose reference data to a web view
through annotating accessor methods in a controller class with
@RequestMapping
methods. Such accessor
methods are allowed to have any arguments that
@RequestMapping
methods support, returning
the model attribute value to expose.
Note however that reference data and all other model content is
not available to web views when request processing results in an
Exception
since the exception could be raised at any time
making the content of the model unreliable. For this reason
@ExceptionHandler
methods do not provide
access to a Model
argument.

public abstract java.lang.String value
The default model attribute name is inferred from the declared attribute type (i.e. the method parameter type or method return type), based on the non-qualified class name: e.g. "orderAddress" for class "mypackage.OrderAddress", or "orderAddressList" for "List<mypackage.OrderAddress>".
