Is there any way to comprehensively capture the supplementation of exceptions in play framework (2.3)?
GlobalSettings.onError captures exceptions during normal request processing.
defaction=Action{
Ok.chunked (Enumerator.outputStream(o=>csvWrite(o))>>Enumerator.eof)
}
defcsvWrite(o:OutputStream) = through new Exception()
If you want to export asynchronously using Enumerator.outputStream, for example, in , an exception occurs inside it (csvWrite in the example above), the console will only display an error at the debug level.
What I want to do is catch an exception and throw up a log with a stack trace at the error level (and send an alert email, etc.).Of course, I can try-catch it individually, but I think I'll forget it somewhere. So I'm looking for a mechanism that would work if I set up one (or some) for the entire application. Do you have one?
scala playframework
I'm not very confident, and there are some terrible examples that I probably can't save with this pattern
(Example https://github.com/playframework/playframework/pull/3707)
However, one thing to consider is that Scala's own ExecutionContext
has a mechanism to handle exceptions that were not caught regardless of play, so would you like to use the explicitly set ExecutionContext
?
By default, the implementation should only be used to printStackTrace
