For more advanced handling of rejections refer to the handleRejections directive which provides a nicer DSL for building rejection handlers.
Example
- Scala
-
def isMethodRejection: Rejection => Boolean = {
case MethodRejection(_) => true
case _ => false
}
val route =
cancelRejections(isMethodRejection) {
post {
complete("Result")
}
}
// tests:
Get("/") ~> route ~> check {
rejections shouldEqual Nil
handled shouldEqual false
}
- Java
-
final Predicate<Rejection> isMethodRejection = p -> p instanceof MethodRejection;
final Route route = cancelRejections(
isMethodRejection, () -> post(() -> complete("Result"))
);
// tests:
runRouteUnSealed(route, HttpRequest.GET("/"))
.assertRejections();
