Scala enumeration serialization in jersey/jackson is not working for me -

i've read jackson-module-scala page on enumeration handling (https://github.com/fasterxml/jackson-module-scala/wiki/enumerations). still i'm not getting work. essential code goes this:

@path("/v1/admin") @produces(array(mediatype.application_json + ";charset=utf-8")) @consumes(array(mediatype.application_json + ";charset=utf-8")) class restservice { @post @path("{type}/abort") def abortupload(@pathparam("type") typename: resourcetypeholder) { ... } } object resourcetype extends enumeration { type resourcetype = value val ssr, roadsegments, tmc, gab, tne = value } class resourcetypetype extends typereference[resourcetype.type] case class resourcetypeholder( @jsonscalaenumeration(classof[resourcetypetype]) resourcetype:resourcetype.resourcetype )

this how it's supposed work, right? still these errors:

following issues have been detected: warning: no injection source found parameter of type public void no.tull.restservice.abortupload(no.tull.resourcetypeholder) @ index 0. unavailable org.glassfish.jersey.server.model.modelvalidationexception: validation of application resource model has failed during application initialization. [[fatal] no injection source found parameter of type public void no.tull.restservice.abortupload(no.tull.resourcetypeholder) @ index 0.; source='resourcemethod{httpmethod=post, consumedtypes=[application/json; charset=utf-8], producedtypes=[application/json; charset=utf-8], suspended=false, suspendtimeout=0, suspendtimeoutunit=milliseconds, invocable=invocable{handler=classbasedmethodhandler{handlerclass=class no.tull.restservice, handlerconstructors=[org.glassfish.jersey.server.model.handlerconstructor@7ffe609f]}, definitionmethod=public void no.tull.restservice.abortupload(no.tull.resourcetypeholder), parameters=[parameter [type=class no.tull.resourcetypeholder, source=type, defaultvalue=null]], responsetype=void}, namebindings=[]}'] @ org.glassfish.jersey.server.applicationhandler.initialize(applicationhandler.java:467) @ org.glassfish.jersey.server.applicationhandler.access$500(applicationhandler.java:163) @ org.glassfish.jersey.server.applicationhandler$3.run(applicationhandler.java:323) @ org.glassfish.jersey.internal.errors$2.call(errors.java:289) @ org.glassfish.jersey.internal.errors$2.call(errors.java:286)

i have assembled tiny runnable project (while trying eliminate other complications) demonstrates problem: project.tgz

update: created sbt-file see if gradle building unusual build. got same result, build.sbt:

name := "project" version := "1.0" scalaversion := "2.10.4" val jacksonversion = "2.4.1" val jerseyversion = "2.13" librarydependencies ++= seq( "com.fasterxml.jackson.core" % "jackson-annotations" % jacksonversion, "com.fasterxml.jackson.core" % "jackson-databind" % jacksonversion, "com.fasterxml.jackson.jaxrs" % "jackson-jaxrs-json-provider" % jacksonversion, "com.fasterxml.jackson.jaxrs" % "jackson-jaxrs-base" % jacksonversion, "com.fasterxml.jackson.module" % "jackson-module-scala_2.10" % jacksonversion, "org.glassfish.jersey.containers" % "jersey-container-servlet-core" % jerseyversion ) seq(websettings :_*) librarydependencies ++= seq( "org.eclipse.jetty" % "jetty-webapp" % "9.1.0.v20131115" % "container", "org.eclipse.jetty" % "jetty-plus" % "9.1.0.v20131115" % "container" )

... , project/plugins.sbt:

you seem perchance have few problems tarball.

you need add together scala modules jackson able utilize scala functionality. can done doing this:

val jsonobjectmapper = new objectmapper() jsonobjectmapper.registermodule(defaultscalamodule) val jsonprovider: jacksonjsonprovider = new jacksonjsonprovider(jsonobjectmapper)

according working jersey-jackson example. need inject org.glassfish.jersey.jackson.jacksonfeature bailiwick of jersey found in jersey-media-json-jackson. restapplication.scala came out this

import javax.ws.rs.core.application import javax.ws.rs.ext.{contextresolver, provider} import com.fasterxml.jackson.databind.objectmapper import com.fasterxml.jackson.module.scala.defaultscalamodule import com.google.common.collect.immutableset import org.glassfish.jersey.jackson.jacksonfeature @provider class objectmapperprovider extends contextresolver[objectmapper] { val defaultobjectmapper = { val jsonobjectmapper = new objectmapper() jsonobjectmapper.registermodule(defaultscalamodule) jsonobjectmapper } override def getcontext(typ: class[_]): objectmapper = { defaultobjectmapper } } class restapplication extends application { override def getsingletons: java.util.set[anyref] = { immutableset.of( new restservice, new objectmapperprovider, new jacksonfeature ) } }

the real issue, though, @pathparam annotation. code path doesn't invoke jackson @ all. however, what's interesting bailiwick of jersey appears generically back upwards parsing type has constructor of single string. if modify resourcetypeholder can functionality want after all.

case class resourcetypeholder(@jsonscalaenumeration(classof[resourcetypetype]) resourcetype:resourcetype.resourcetype) { def this(name: string) = this(resourcetype.withname(name)) }

you might able add together generic back upwards enum holders bailiwick of jersey injectable provider. however, hasn't come in dropwizard-scala, project suffer same fate uses bailiwick of jersey too. imagine it's either impossible, or not mutual plenty have done work. when comes enum's, tend maintain mine in java.
