我正在尝试使用Deadbolt进行授权,使用Silhouette或SecureSocial进行身份验证,使用Play 2.3.3和Scala 2.11.1.

MyDeadboltHandler有一个要覆盖的getSubject,为此我需要从请求中检索用户.使用非常直接的SecureSocial 2.

override def getSubject[A](request: Request[A]): Option[Subject] = {
  SecureSocial.currentUser(request) match {
  case Some(identity) => // Subject could be created and returned
  case _ => None
}

我无法在Silhouette中找到任何方法来获取"当前用户".Silhouette和SecureSocial都有一个SecuredRequest [AnyContent](扩展的WrappedRequest),而MyDeadboltHandler中的getRequest方法需要一个Request [A].SecuredRequest在MyDeadboltHandler中不可见的特征中定义.

任何建议都非常感谢.

在一个有两个子项目的Play项目中,我们正在尝试使用HikariCP,它似乎没有将连接释放回池并抛出此异常:

java.sql.SQLException: Timeout of 30000ms encountered waiting for connection.

以下是六个简单查询后调试显示的内容:

[DEBUG] c.z.h.p.HikariPool - Before cleanup pool stats pool1 (total=5, inUse=5, avail=0, waiting=1)
[DEBUG] c.z.h.p.HikariPool - After cleanup pool stats pool1 (total=5, inUse=5, avail=0, waiting=1)

我正在研究Scala 2.10.2.运行以下简单代码时:

object Test {
  var input  = "**** ANY STRING LONGER THAN 65535 CHARACTERS ****"
  def main(args: Array[String]) {
      println(input)
  }
}

抛出以下错误:

这是一个错误还是一个奇怪的限制？

谢谢,
