Interface ServletRequestListener
- All Superinterfaces:
EventListener
A ServletRequest is defined as coming into scope of a web application when it is about to enter the first servlet or filter of the web application, and as going out of scope as it exits the last servlet or the first filter in the chain.
In order to receive these notification events, the implementation
class must be either declared in the deployment descriptor of the web
application, annotated with WebListener
,
or registered via one of the addListener methods defined on
ServletContext
.
Implementations of this interface are invoked at their
requestInitialized(javax.servlet.ServletRequestEvent)
method in the order in which they have been
declared, and at their requestDestroyed(javax.servlet.ServletRequestEvent)
method in reverse
order.
