Package org.dellroad.stuff.vaadin7

Class VaadinApplicationScope

java.lang.Object

org.dellroad.stuff.vaadin7.VaadinApplicationScope

All Implemented Interfaces:

SessionDestroyListener, Serializable, BeanFactoryPostProcessor, Scope

public class VaadinApplicationScope
extends Object
implements Scope, BeanFactoryPostProcessor, SessionDestroyListener

A Spring custom Scope for Vaadin applications.

This scopes beans to the lifetime of the VaadinSession (formerly known as "Vaadin application"). Spring destroy-methods will be invoked when the VaadinSession is closed.

To enable this scope, simply add this bean to your application context as a singleton (it will register itself):

  <!-- Enable the "vaadinApplication" custom scope -->
  <bean class="org.dellroad.stuff.vaadin7.VaadinApplicationScope"/>
 

Then declare scoped beans normally using the scope name "vaadinApplication".
