scala - 无法部署 Scala Web 应用程序

问题描述

我正在尝试部署一个使用 Play 框架和 Scala 构建的简单 Web 应用程序。应用程序工作正常，当我使用sbt run命令运行应用程序时，但是，当我尝试在本地服务器中部署应用程序时，使用sbt dist命令，我收到以下消息

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.google.inject.internal.cglib.core.$ReflectUtils$1 (file:/D:/Scala/SomeDomain/SomeProject/target/universal/SomeProject-1.0-SNAPSHOT/lib/com.google.inject.guice-4.2.2.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain)

Oops, cannot start the server.
com.google.inject.CreationException: Unable to create injector, see the following errors:

  at initializer.ApplicationInitializer.configure(ApplicationInitializer.scala:12) (via modules: com.google.inject.util.Modules$OverrideModule -> initializer.ApplicationInitializer)
  while locating initializer.ServiceInitializer

我使用的是 Windows，我提取了生成的文件并从目录中.zip执行了该文件。.bat/bin

构建.sbt


version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayScala, LauncherJarPlugin)

scalaVersion := "2.12.10"

libraryDependencies += guice
libraryDependencies += "org.scalatestplus.play" %% "scalatestplus-play" % "5.0.0" % Test
libraryDependencies += "postgresql" % "postgresql" % "9.1-901-1.jdbc4"

插件.sbt

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.8.0")
addSbtPlugin("org.foundweekends.giter8" % "sbt-giter8-scaffold" % "0.11.0")

解决方案

似乎您的应用程序的某些组件需要一个目录存在：

java.io.IOException: Dictionary directory does not exist: D:\Scala\SomeDomain\SomeProject\target\universal\SomeProject-1.0-SNAPSHOT\bin\dict

确保创建目录，或将丢失的文件添加到您的 dist。
