问题
I've migrated my project to 0.13.5 and started using the xsbt-web-plugin.
I'd like to configure logback to be using a configuration file outside the classpath which is set by a system property logback.configurationFile
(so I can keep the logconfig outside the war file).
Previously I would simply set:
System.setProperty("logback.configurationFile", "/some/path/logback.xml")
inside the project/build.scala
and logback would pick it up.
However, after upgrading sbt to 0.13.5 and migrating to the xsbt-web-plugin system properties set in sbt don't seem to be available at runtime(jetty).
I've tried setting system properties in different ways, also by passing it along using the -D
flag when starting sbt.
On the sbt console I can see the property:
eval sys.props("logback.configurationFile")
[info] ans: String = /some/path/logback.xml
But it's not available inside the webapp.
Any ideas on how to set system properties to be available inside the webapp?
I've tried both jetty()
and tomcat()
. Same behaviour.
Update: I ended up with:
jetty(options = new ForkOptions(runJVMOptions = Seq("-Dlogback.configurationFile=/some/path/logback.xml")))
that works.
回答1:
Use javaOptions in container += "-Dlogback.configurationFile=/some/path/logback.xml"
as described in Set forked JVM options.
javaOptions
alone (without in container
) should work, too, as could be seen in inspect actual
under Dependencies
and Delegates
:
[play-new-app] $ inspect actual container:javaOptions
