Request Listeners
Sling provides the possibility to "listen" to a request processed by the Sling Engine (SlingMainServlet). To get notified you implement the service interface org.apache.sling.api.request.SlingRequestListener.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | public interface SlingRequestListener { static final String SERVICE_NAME = "org.apache.sling.api.request.SlingRequestListener"; /** * This method is called from the Sling application for every * <code>EventType</code> appearing during the dispatching of * a Sling request * * @param sre the object representing the event * * @see org.apache.sling.api.request.SlingRequestEvent.EventType */ public void onEvent( SlingRequestEvent sre ); } |
There are no special properties to set.
Supported types of events¶
At the moment you will get two different types of SlingRequestEvent:
events types (SlingRequestEvent.EventType) |
point in time |
|---|---|
| EVENT_INIT | after entering the service method in SlingMainServlet. Note that this will be after the handleSecurity call. |
| EVENT_DESTROY | at the end of the service method in SlingMainServlet |
