    @Documented
    public @interface ModelAttribute

Annotation that binds a method parameter or method return value to a named model attribute, exposed to a web view. Supported for `RequestMapping` annotated handler classes.

Can be used to expose command objects to a web view, using specific attribute names, through annotating corresponding parameters of a `RequestMapping` annotated handler method).

Can also be used to expose reference data to a web view through annotating accessor methods in a controller class which is based on `RequestMapping` annotated handler methods, with such accessor methods allowed to have any arguments that `RequestMapping` supports for handler methods, returning the model attribute value to expose.
