问题 For my Spark API I'm building integration tests. Sometimes I want to stop and start the Spark instance. When I do that I sometimes run into the problem that I'm creating a new Spark instance, while the old one is still shutting down on a separate thread. It would be helpful to know when the Spark instance actually shut down. First I start my Spark instance like this: Spark.init(); Spark.awaitInitialization(); Then I stop it like this: Spark.stop(); Now after I call stop() , the Spark Service

问题 I'm working on a REST server built with Java Spark, and I was wondering about the difference between the following two syntaxes for defining path parameters, using :path-parameter vs {path-parameter} : path("/containers/:container-id", () -> { ...} ) path("/shipments/{shipment-id}", () -> { ... } ) At one point, when querying the path parameters on the path /{handler-id} (which is nested inside /v1 and /handlers ), I had to change the syntax from the : form to the {} form to get Spark to not

问题 I'm doing a project using Spark Java. On the server side, some images are created and I want them to be available in the client. Since I have a static content directory, after creating the image on the server side, I place it in that directory. However, this file is not available unless I reboot the server. I guess there must be a way to refresh the static directory file for Spark Java on runtime so that requests of on-runtime created images can be fulfilled. Right? Thanks! 回答1: The

问题 In my spark-java project, I put css file and js file into folder static in src/main/resources . I use Spark.staticFileLocation("/static") to set the static file path.
