public interface RequestContextController
The CDI container provides a built in instance of RequestContextController that is dependent scoped for the purposes of activating and deactivating. For example:@Inject private RequestContextController requestContextController; public void doRequest(String body) { // activate request context requestContextController.activate(); // do work in a request context. // deactivate the request context requestContextController.deactivate(); }
Once the request context has been deactivated, you may activate it once again, creating a brand new request context. The activated request context is bound to the current thread, any injection points targeting a request scoped bean will be satisfied with the same request scoped objects.- Since:
