scala – 如何强制Logger.debug输出在Play！框架specs2测试？

The logger is disabled in test mode for now because it was causing an
huge PermGen space leak when running tests. But we are working to run
tests in a forked JVM so we will enable it again soon.

作为解决方法，我创建了我自己的记录器这样(Scala代码)：

import play.api.{Play,LoggerLike,Logger}
import org.slf4j.LoggerFactory
import org.slf4j.impl.SimpleLoggerFactory

object MyLogger extends LoggerLike {

  val factory = if (Play.isTest(Play.current)) {
    new SimpleLoggerFactory()
  } else {
    LoggerFactory.getILoggerFactory
  }

  val redirectDebugToInfo = factory.isInstanceOf[SimpleLoggerFactory]

  val logger = factory.getLogger("application")

  def apply(name: String): Logger = new Logger(factory.getLogger(name))

  def apply[T](clazz: Class[T]): Logger = new Logger(factory.getLogger(clazz.getCanonicalName))

  // this method is to make debug statements to show up in test mode
  override def debug(m: => String) = {
    if (redirectDebugToInfo) {
      info(m)
    } else {
      super.debug(m)
    }
  }
}

我不知道这个代码关于PermGen泄漏的一般行为，但到目前为止我没有这个问题。
要使其工作，您需要添加此依赖关系：

"org.slf4j" % "slf4j-simple" % "1.6.4"
