Question

我正在使用play-framework 2.3.x reactivemongo-extension JSON type。以下是我从db获取数据的代码，如下所示：

def getStoredAccessToken(authInfo: AuthInfo[User]) = {
println(">>>>>>>>>>>>>>>>>>>>>>: BEFORE"); //$doc("clientId" $eq authInfo.user.email, "userId" $eq authInfo.user._id.get)
var future = accessTokenService.findRandom(Json.obj("clientId" -> authInfo.user.email, "userId" -> authInfo.user._id.get));
println(">>>>>>>>>>>>>>>>>>>>>>: AFTER: "+future);
future.map { option => {
  println("*************************** ")
  println("***************************: "+option.isEmpty)
  if (!option.isEmpty){
   var accessToken = option.get;println(">>>>>>>>>>>>>>>>>>>>>>: BEFORE VALUE");
   var value = Crypto.validateToken(accessToken.createdAt.value)
   println(">>>>>>>>>>>>>>>>>>>>>>: "+value);
   Some(scalaoauth2.provider.AccessToken(accessToken.accessToken, accessToken.refreshToken, authInfo.scope, 
       Some(value), new Date(accessToken.createdAt.value)))
  }else{
    Option.empty
  }
}}

}

当我使用BSONDao和BsonDocument获取数据时，此代码已成功运行，但转换为JSONDao后，我收到以下错误：

注意：有时候这段代码会运行，但有些时候会在转换为JSON后抛出异常

play - Cannot invoke the action, eventually got an error: java.lang.IllegalArgumentException: bound must be positive
application -

以下是应用程序完全异常删除跟踪的日志，如下所示：

问题解决了，但我不确定，为什么这会产生，我认为JPanel库存在问题。因为当我使用reactivemongo-extension JSONDao代替findOne时代码运行成功，但findRandom在BSON dao上运行良好。仍然没有找到确切的问题是什么，但以下是已解决的代码。

findRandom

}

Play-Framework：2.3.x：play - 无法调用动作，最终出错：java.lang.IllegalArgumentException：
