如何在使用SBT& amp;的开发和生产中正确地管理logback配置.斯卡拉(Scala)? [英] How to properly manage logback configrations in development and production using SBT & Scala?
问题描述
我有一个非常漂亮的Scalatra项目，它使用Logback进行记录.
I have a pretty standard Scalatra project using Logback for logging.
在 logback手册之后，我为开发配置添加了logback-test.xml(调试日志)，同时保持生产logback.xml.
Following the logback manual I have added a logback-test.xml for my development configuration (logs of debugs), whilst maintaining a production logback.xml.
但是，在开发中，使用xsbt-web-plugin来运行容器并重新加载代码时，我的应用似乎只能使用logback.xml.
However, in development while using the xsbt-web-plugin to run a container with code reloading, my app only seems to pick up the logback.xml.
如何获得所需的行为?:
How do I get the desired behavior?:
- 在开发模式(
./sbt container:start)中，应用使用logback-test.xml - 使用 SBT组装组装成zip时，请排除测试配置.
- In development mode (
./sbt container:start) the app useslogback-test.xml - When assembled into a zip using SBT-assembly, exclude the test config.
目前这些似乎都不起作用.
Currently neither of these seems to work.
推荐答案
您正在滥用logback-test.xml.它仅适用于类单元测试，应放置在src/test/resources中(该产品会自动从产品中排除).要实现您想要的目标-您可以通过系统属性设置logback-dev.xml的路径:
You're misusing logback-test.xml. It's intended for unit-like tests only and should be placed in src/test/resources (which is automatically excluded from prod). To achieve what you want - you may set up path to your logback-dev.xml by system property:
javaOptions in container += "-Dlogback.configurationFile=/some/path/logback-dev.xml"
此路径可能是相对的.参见 https://stackoverflow.com/a/26538449/1809978
This path may be relative. See, https://stackoverflow.com/a/26538449/1809978
在我的实践中，即使在产品(它指向某个外部位置)中，我们也不打包logback.xml来具有临时更改日志记录配置的功能.
In my practice we don't pack logback.xml even in prod (it's pointed to some external place) to have ability to change logging configuration ad-hoc.
P.S.如果您也有兴趣从sbt-assembly中排除文件-这可能会帮助
P.S. If you're also interested about excluding files from sbt-assembly - this may help
