Scala 升级到Play Framework 2.2安全社会问题

您好，我正在尝试升级到Play 2.2，在工作中遇到一些问题

我使用的是论坛中建议的最新快照，但出现以下错误。verify错误表示二进制文件和我正在使用的版本之间的编译源代码不兼容。我曾尝试在Java1.6和1.7之间切换，但遇到了同样的问题。 我知道securesocial只为Play 2.1做好准备，但也有使用securesocial snapshot的Play 2.2示例。 也许我应该再次降级

我的Build.scala

object ApplicationBuild extends Build {

  val appName = "rm-play"
  val appVersion = "1.0-SNAPSHOT"

  val appDependencies = Seq(
    // Add your project dependencies here,
    javaCore,
    javaJdbc,
    javaEbean,
    "com.google.guava" % "guava" % "15.0",
    "org.codehaus.jackson" % "jackson-core-asl" % "1.9.13",
    "com.dbdeploy" % "maven-dbdeploy-plugin" % "3.0M3",
    "postgresql" % "postgresql" % "9.1-901.jdbc4",
    "joda-time" % "joda-time" % "2.3",
    "com.github.mumoshu" % "play2-memcached_2.10" % "0.3.0.3",
    "net.spy" % "spymemcached" % "2.9.1",
    "com.amazonaws" % "aws-java-sdk"% "1.6.11",
    "ws.securesocial" %% "securesocial" % "master-SNAPSHOT"
  )


  val main = play.Project(appName, appVersion, appDependencies).settings(
    resolvers += Resolver.sonatypeRepo("snapshots"),
    javacOptions in Compile ++= Seq("-source", "1.7", "-target", "1.7")
  )

} 

plugin.sbt

logLevel := Level.Warn

// The Typesafe repository
resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"

// Use the Play sbt plugin for Play projects
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % System.getProperty("play.version")

SecuresSocial 2.1.3和主快照应与Play 2.2.1配合使用。我认为导致问题的原因是您的UserService实现是针对1.7编译的，但试图加载它的代码是针对1.6编译的

---

默认情况下，Scala2.10为1.6生成字节码。您可以生成1.7，但据我所知，该功能是实验性的。首选1.6。我会将sbt文件更改为生成1.6字节码。这应该可以让它工作。

因此，事实证明，它比编译版本的差异更无害

导致错误的原因是下面的行，将其更改为使用方法，而不是字段更正了问题

在日志中我发现了错误

原因: 类型“securesocial/core/java/Token”（当前帧，局部变量[4]）不可分配给“model/LocalToken”（堆栈映射，局部变量[4]）

更改为以下解决了该问题

localToken.uuid = token.getUuid();

---

我不确定这有什么帮助，因为我对scala没有太多的经验，但字段调用生成了方法，可能正是这导致了问题。

play 2.2使用build.sbt而不是build.scala。你需要在build.sbt中编写你的依赖项。我想你可以同时使用这两个。除了securesocial之外，其他一切都可以正常工作，它确实能够降低依赖项。我在2.2.2中也有同样的错误，但此修复对我不起作用。即使更改为token.getEmail（）和token.getIsSignUp（）。使用export _JAVA_OPTIONS=“-XX:-UseSplitVerifier”对我来说也很有效。

localToken.uuid = token.getUuid();
