Examples of RequestScope

com.ibatis.sqlmap.engine.scope.RequestScope
Request based implementation of Scope interface
de.danet.an.util.logging.RequestScope
This class denotes a request scope opened by the {@link RequestLog RequestLog}. @author Michael Lipp
jodd.petite.scope.RequestScope
Request scope.
org.glassfish.jersey.process.internal.RequestScope
is execute in the new request scope. // The following call will cause that the // RequestScope.Instance will not be released // automatically and we will have to release // it explicitly at the end. return requestScope.suspendCurrent(); } }); requestScope.runInScope(requestScopeInstance, new Runnable() { @Override public void run() { // This is execute in the same request scope as code above. } }); // we must release the scope instance explicitly requestScopeInstance.release();
In the previous example the {@link RequestScope.Instance request scope instance}was suspended and retrieved which also informs {@code requestScope} that itshould not automatically release the instance once the running task is finished. The {@code requestScopeInstance} is then used to initialize the nextrequest-scoped execution. The second task will run in the same request scope as the first task. At the end the suspended {@code requestScopeInstance} must bemanually {@link RequestScope.Instance#release released}. Not releasing the instance could cause memory leaks. Please note that calling {@link RequestScope#suspendCurrent}does not retrieve an immutable snapshot of the current request scope but a live reference to the internal {@link RequestScope.Instance request scope instance}which may change it's state during each request-scoped task execution for which this scope instance is used.

org.springframework.web.context.request.RequestScope
Request-backed {@link org.springframework.beans.factory.config.Scope}implementation.
Relies on a thread-bound {@link RequestAttributes} instance, whichcan be exported through {@link RequestContextListener}, {@link org.springframework.web.filter.RequestContextFilter} or{@link org.springframework.web.servlet.DispatcherServlet}.
This Scope will also work for Portlet environments, through an alternate RequestAttributes implementation (as exposed out-of-the-box by Spring's {@link org.springframework.web.portlet.DispatcherPortlet}. @author Rod Johnson @author Juergen Hoeller @author Rob Harrop @since 2.0 @see RequestContextHolder#currentRequestAttributes() @see RequestAttributes#SCOPE_REQUEST @see RequestContextListener @see org.springframework.web.filter.RequestContextFilter @see org.springframework.web.servlet.DispatcherServlet @see org.springframework.web.portlet.DispatcherPortlet
