Class SessionContextRequestHandler

java.lang.Object

org.apache.cayenne.configuration.web.SessionContextRequestHandler

All Implemented Interfaces:

RequestHandler

public class SessionContextRequestHandler
extends Object
implements RequestHandler

Default implementation of the RequestHandler that stores per-user ObjectContext in a web session and binds it to request thread. Note that using this handler would force HttpSession creation, that may not be desirable in many cases. Also session-bound context may result in a race condition with two user requests updating the same persistent objects in parallel.

User applications in most cases should provide a custom RequestHandler that implements a smarter app-specific strategy for providing ObjectContext.

For stateless (per request) context creation use StatelessContextRequestHandler.
