Tapping into Stripes - Stripes...and Java Web Development is Fun Again - page 290

public abstract class BaseActionBean implements ActionBean {
@Inject protected AttachmentDao attachmentDao;
@Inject protected ContactDao contactDao;
@Inject protected FolderDao folderDao;
@Inject protected MessageDao messageDao;
@Inject protected UserDao userDao;

}

public class MyActionBeanContext extends ActionBeanContext {
@Inject protected FolderDao folderDao;
@Inject protected UserDao userDao;

}

That's all there is to it. To inject dependencies on other Stripes objects,
we'd use the same technique as we did for Spring on page 265 : subclass
the default factory, retrieve the object, and inject the dependencies.
Instead of this:

SpringHelper.injectBeans(object, context);

we'd use the following:

GuiceInterceptor.getInjector().injectMembers(object);

13.5 Another Interceptor Example: Ensuring Login

The Guice interceptor example was pretty cool in terms of implementing
Guice support, but it was rather light on the actual interceptor code:

Download email_33/src/stripesbook/ext/guice/interceptor/GuiceInterceptor.java

package stripesbook.ext.guice.interceptor;
@Intercepts(LifecycleStage.ActionBeanResolution)
public class GuiceInterceptor
implements Interceptor, ConfigurableComponent

{

/ * ... * /

public Resolution intercept(ExecutionContext context)
throws Exception

{

injector.injectMembers(context.getActionBeanContext());
Resolution resolution = context.proceed();
injector.injectMembers(context.getActionBean());
return resolution;

}

}
