@Target({TYPE,METHOD})
@Retention(RUNTIME)
@Documented
@Scope("session")
public @interface SessionScope
```
@SessionScope is a specialization of @Scope for a component whose lifecycle is bound to the current web session.
Specifically, @SessionScope is a composed annotation that acts as a shortcut for @Scope("session") with the default proxyMode() set to TARGET_CLASS.
@SessionScope may be used as a meta-annotation to create custom composed annotations.
