Czy istnieje jakikolwiek zakres, taki jak JSF@ViewScoped na wiosnę 3.0? Mam aplikację korzystającą z JSF + Spring, w której ziarna fasoli są zarządzane przez Spring. Na wiosnę nie znalazłem żadnego zakresu, takiego jak JSF wiew zasięgu. Widziałem blogaPrzenoszenie ViewScope JSF 2.0 do Spring 3.0, ale dla mnie to nie zadziałało.

Oto moja próba niestandardowego zakresu Spring:

import java.util.Map;

import javax.faces.context.FacesContext;

import org.springframework.beans.factory.ObjectFactory;
import org.springframework.beans.factory.config.Scope;

/**
 * Implements the JSF View Scope for use by Spring. This class is registered as a Spring bean with the CustomScopeConfigurer.
*/
public class ViewScope implements Scope {

    public Object get(String name, ObjectFactory<?> objectFactory) {

        System.out.println("**************************************************");
        System.out.println("-------------------- Getting objects For View Scope ----------");
        System.out.println("**************************************************");
        if (FacesContext.getCurrentInstance().getViewRoot() != null) {
            Map<String, Object> viewMap = FacesContext.getCurrentInstance().getViewRoot().getViewMap();
            if (viewMap.containsKey(name)) {
                return viewMap.get(name);
            } else {
                Object object = objectFactory.getObject();
                viewMap.put(name, object);
                return object;
            }
        } else {
            return null;
        }
    }

    public Object remove(String name) {
        System.out.println("**************************************************");
        System.out.println("-------------------- View Scope object Removed ----------");
        System.out.println("**************************************************");

        if (FacesContext.getCurrentInstance().getViewRoot() != null) {
            return FacesContext.getCurrentInstance().getViewRoot().getViewMap().remove(name);
        } else {
            return null;
        }
    }

    public void registerDestructionCallback(String name, Runnable callback) {
        // Do nothing
    }

    public Object resolveContextualObject(String key) {         return null;
    }

    public String getConversationId() {
        return null;
    }

}

application-context.xml:

<bean class="org.springframework.beans.factory.config.CustomScopeConfigurer">
    <property name="scopes">
            <map>
                <entry key="view">
                    <bean class="com.delta.beans.ViewScope"/>
                </entry>
            </map>
        </property>
 </bean>
