问题 I'm making webapp using scalatra framework via sbt & xsbt-web-plugin. I want to package all resources(templates, css, js) into a single jar. In sbt with sbt-assembly plugin, assembly command makes single jar which includes all of project's dependencies. $ java -jar myproject.jar and I open it in browser Could not load resource: [/WEB-INF/views/index.scaml]; are you sure it's within [null]? I unzipped jar to confirm that it does not include src/main/webapp/* . How can I config sbt for

问题 In our Scala/Scalatra project, we have this merge policy for the plugin sbt-assembly : assemblyMergeStrategy in assembly := { case x => val oldStrategy = (assemblyMergeStrategy in assembly).value oldStrategy(x) } [error] 11 errors were encountered during merge java.lang.RuntimeException: deduplicate: different file contents found in the following: ~/.ivy2/cache/org.scalatra/scalatra_2.11/jars/scalatra_2.11-2.3.1.jar:mime.types ~/.ivy2/cache/com.amazonaws/aws-java-sdk-s3/jars/aws-java-sdk-s3-1

问题 I am attempting to produce JSON in a Scala app using json4s. Fairly straight forward, Here's some sample value I put together to test it in my Scalatra app: import org.json4s._ import org.json4s.JsonDSL._ object JsonStub { val getPeople = ("people" -> ("person_id" -> 5) ~ ("test_count" -> 5)) } In my controller, I simply have: import org.json4s._ import org.json4s.JsonDSL._ import org.json4s.{DefaultFormats, Formats} class FooController(mongoDb: MongoClient)(implicit val swagger: Swagger)

问题 Just ran into this sample code learning about Commands in Scalatra: protected def handle: Handler = { case c: CreateTodoCommand => add(newTodo(~c.name.value)) } In this particular case, what exactly is the relevance of ~ in ~c.name.value ? Not sure where to find more documentation on this particular symbol. 回答1: In Scala: ~x translates to x.unary_~ (this also applies to + , - and ! as explained in this post). So your example translates to: add(newTodo(c.name.value.unary_~)) The documentation

问题 I have a Scalatra app that compiles CoffeeScript, using https://github.com/softprops/coffeescripted-sbt, to a default location, target/scala-2.9.1/resource_managed/main/js . I want to put the generated javascripts somewhere available to me publicly, in a folder called src/main/webapp/coffee , but the example given defaults to `/target/...' resourceManaged in (Compile, CoffeeKeys.coffee)) <<= (crossTarget in Compile)(_ / "your_preference" / "js") My build.sbt: seq(coffeeSettings: _*) // doesn

问题 I want to launch scalatra server from sbt. How do I do that? The following does launch scalatra: sbt "container:start" But it exits immediately: [info] starting server ... [success] Total time: 2 s, completed Sep 12, 2015 2:39:32 PM > [info] waiting for server to shut down... Most preferably the whole thing would run in a nohup as a daemon process. 回答1: Don't do it on one line. Use two commands. ./sbt container:start 回答2: sbt "; <command>; console" does the trick. Note the initial semicolon

问题 By default, Scalatra expects the "webapp" directory to be at src/main/webapp . How could that be changed to, e.g., content/doc-root ? sbt allows for customizing its default directories using something like the following: scalaSource <<= (baseDirectory)(_ / "src") So I assume it's just a matter of knowing the right "configuration key" to use... 回答1: @Kelsey Gilmore-Innis has the right answer, but since it's not accepted let's break it, break it, break it down. First, I'm assuming you're

问题 I am trying to unit test an upload call but I get this error for the following code: @MultipartConfig(maxFileSize = 3145728) class WebServlet extends ScalatraServlet with FileUploadSupport { override def isSizeConstraintException(e: Exception) = e match { case se: ServletException if se.getMessage.contains("exceeds max filesize") || se.getMessage.startsWith("Request exceeds maxRequestSize") => true case _ => false } error { case e: SizeConstraintExceededException => RequestEntityTooLarge("too

问题 I have an angularJS form which posts data to a scalatra servlet. When the form gets submitted I can't get any form params in my scalatra servlet. Below is my code AngularJS $scope.createUser = function() { $http.post('/createUser',{name:$scope.name,email:$scope.email,pwd:$scope.pwd}). success(function(data, status, headers, config) { alert("success " + data) }). error(function(data, status, headers, config) { alert("failure =>" +data) }); }; }); }; HTML form <form ng-controller=
