Handy classes for instrumented request tracing
AspectjWeaver is needed at runtime for this so we can instrument scala.concurrent.Future and pass the ThreadLocal context to the thread running the Future.
Example Usage in a Play! application:
Global.scala
override def doFilter(next: EssentialAction): EssentialAction = {
Filters(super.doFilter(next), RequestIdTraceFilter)
}
override def onRouteRequest(request : RequestHeader): Option[Handler] = {
Tracer.setCurrentContext(RequestContext(Guid.randomGuid().toString()))
super.onRouteRequest(request)
}
Logback Logging
<conversionRule conversionWord="traceToken" converterClass="com.teambytes.handy.tracing.logback.LogbackTraceTokenConverter"/>
...
<pattern>%d{HH:mm:ss.SSS} [%traceToken] [%thread] %level %logger{36} - %message%n%ex</pattern>
