如何记录播放框架启动错误

数据库连接错误未在生产模式中记录

在下面的堆栈跟踪中，只有第一行：[info]应用程序 - 为数据源创建池＆＃39;默认＆＃39;转到application.log。该例外仅在play.core.server.RealServerProcess#exit

中打印到stderr

我可以使用http://projects.lidalia.org.uk/sysout-over-slf4j/quickstart.html，但由于数据库连接发生之前无法在应用程序onStart中完成，所以也许我需要编写一个模块？

子类化GuiceApplicationLoader，它可以工作

play.application.loader = "modules.LogSdtErrLoader"

LogSdtErrLoader.scala 

package modules

import play.api.ApplicationLoader
import play.api.inject.guice.{GuiceApplicationBuilder, GuiceApplicationLoader}
import uk.org.lidalia.sysoutslf4j.context.SysOutOverSLF4J

class LogSdtErrLoader extends GuiceApplicationLoader {

  override final def builder(context: ApplicationLoader.Context): GuiceApplicationBuilder = {
    SysOutOverSLF4J.sendSystemOutAndErrToSLF4J()
    super.builder(context)
  }
}
