Class SpringViewProvider

java.lang.Object

org.vaadin.spring.navigator.SpringViewProvider

All Implemented Interfaces:

com.vaadin.navigator.ViewProvider, Serializable

public class SpringViewProvider
extends Object
implements com.vaadin.navigator.ViewProvider

A Vaadin ViewProvider that fetches the views from the Spring application context. The views must implement the View interface and be annotated with the VaadinView annotation.

Use like this:

         @VaadinUI
         public class MyUI extends UI {

              @Autowired SpringViewProvider viewProvider;

              protected void init(VaadinRequest vaadinRequest) {
                  Navigator navigator = new Navigator(this, this);
                  navigator.addProvider(viewProvider);
                  setNavigator(navigator);
                  // ...
              }
         }
     

View-based security can be provided by creating a Spring bean that implements the ViewProviderAccessDelegate interface. It is also possible to se an 'Access Denied' view by using setAccessDeniedViewClass(Class).
