Annotation Type SessionAttributes

    @Target(value=TYPE)
    @Retention(value=RUNTIME)
    @Inherited
    @Documented
    public @interface SessionAttributes

Annotation that indicates the session attributes that a specific handler uses. This will typically list the names of model attributes which should be transparently stored in the session or some conversational storage, serving as form-backing beans. Declared at the type level, applying to the model attributes that the annotated handler class operates on.

NOTE: Session attributes as indicated using this annotation correspond to a specific handler's model attributes, getting transparently stored in a conversational session. Those attributes will be removed once the handler indicates completion of its conversational session. Therefore, use this facility for such conversational attributes which are supposed to be stored in the session temporarily during the course of a specific handler's conversation.

For permanent session attributes, e.g. a user authentication object, use the traditional `session.setAttribute` method instead. Alternatively, consider using the attribute management capabilities of the generic `WebRequest` interface.

### value

    public abstract String[] value

  The names of session attributes in the model, to be stored in the session or some conversational storage.

  Note: This indicates the model attribute names. The session attribute names may or may not match the model attribute names; applications should not rely on the session attribute names but rather operate on the model only.

  Default:
    {}

### types

    public abstract Class[] types

  The types of session attributes in the model, to be stored in the session or some conversational storage. All model attributes of this type will be stored in the session, regardless of attribute name.
