问题 I'm reading through Derby documentation and following all the instructions. I've successfully installed it (extracted it to my Linux machine and set the DERBY_HOME path).

问题 I have a REST api written by someone else in which the method that handles the request to a particular url accepts a bunch of parameters that are populated from path parameters. @POST @Path("/{classid}/{studentid}/details") @Consumes(MediaType.MULTIPART_FORM_DATA) @SuppressWarnings("unchecked") public Response processFile(@FormDataParam("sourceFile") InputStream aStream, @PathParam("classid") String classId, @PathParam("studentid") String studentId, @Context HttpServletRequest httpRequest) {

问题 I am looking for a persistent session manager which saves the session on file system (like PHP) that can be used with DropWizard. I see there is one Environment.getSessionHandler() , but I see no documentation on it. I could write my own but I am hoping for a cooked meal. Will the above SessionHandler is what I am looking for? And how to use that? 回答1: With dropwizard>0.7 environment.jersey().register(HttpSessionProvider.class); environment.servlets().setSessionHandler(new SessionHandler());

问题 I want to restrict some methods if they are being accessed in a non-secure manner. I'm creating a @Secure annotation that checks whether or not the request was sent over secure channels. However, I cannot create a method injectable that captures the HttpContext of the request. @Documented @Retention(RetentionPolicy.RUNTIME) @Target({ElementType.METHOD}) public @interface Secure { } public class SecureProvider<T> implements InjectableProvider<Secure, AbstractResourceMethod> { @Override public
