Scala Futures-当threadId不相关时跟踪请求上下文

Question

making first steps using Scala promises/futures in a web server (still Jetty/synchronous for now :( ), as expected the threadId is no longer useful for tracking what happened during a single HTTP request processing.

I guess logging a request token will do the trick - is this the recommended approach? if so can you refer me to some code already doing that?

Answer 1

在这种情况下，我的方法是让一个案例类保存上下文数据（例如请求ID），并将其作为implicit参数传递给应用程序的所有层。

Answer 2

请原谅我添加了一个答案，但我只是在scala时间（ http://scalatimes.com/ ）上看到了这一相关想法： http : //www.schibsted.pl/blog/tracing-back-scala-future-chains /要点-用TraceableFuture包装Future，其中添加了“未来堆栈”。
