Typesafe config: Load additional config from path external to packaged scala application

由 南楼画角 提交于 2021-02-05 12:59:08
问题 My scala application will be packaged into a jar. When I run my app, it needs to read an additional config file stored externally to my app jar. I am looking for functionality similar to the Typesafe Config library but other solutions are welcome too ! Is there a way to do something like below: val hdfsConfig = ConfigFactory.load("my_path/hdfs.conf") 回答1: I think what you want is: val myCfg = ConfigFactory.parseFile(new File("my_path/hdfs.conf")) 回答2: If your external configuration is to add

问题 I am attempting to learn to use Slick to query MySQL.

Run a sbt-created app without sbt

由 爷，独闯天下 提交于 2019-12-08 06:40:11
问题 This is somehow a follow-up of this question. When I'm creating a Scala package with sbt, I am able to run it using one of these ways: simply by typing run in the sbt console or by creating a jar file (using either one-jar or assembly ), and the running this jar in the system console by typing java -jar myjar.jar But I don't know how to run my package from the scala program ? (not the sbt scala console, in which everything works fine by typing import mypackage._ ) use my Scala package in

How to force Typesafe Activator to listen 0.0.0.0:8888

由 久未见 提交于 2019-12-03 16:14:33
问题 I recently installed Typesafe Activator to a VM. Applications created by activator can be accessed after port forwarding, but Activator seems to listen localhost. How to change this to WAN? 回答1: It looks like setting system properties http.address and http.port will now do this job, e.g. ./activator -Dhttp.address=0.0.0.0 -Dhttp.port=80 Would launch Activator on a WAN on port 80 (assuming matching permissions, etc). 回答2: It is hardcoded right now and there's no way to change short of

How can I configure system properties or logback configuration variables from typesafe config?

由 穿精又带淫゛_ 提交于 2019-12-03 08:00:06
问题 I have variables with defaults in my logback.xml configuration file, and I would like to be able to optionally set these variables from my typesafe config application.conf file. I am deploying the application using one-jar, and the application.conf file packaged up in the deployable jar contains defaults. I pass -Dconfig.file=foo.conf on execution to provide the path to a server-specific config file. Right now I can also pass -Dlog.level and other variables to override my defaults in logback

Failing to include com.typesafe in build.sbt (for Scala and spray on Heroku)

由 自作多情 提交于 2019-11-30 18:04:36
问题 Trying to bootstrap my boilerplate Scala Spray project on Heroku, I am trying to add the necessary tweaks to my local project as per the Heroku documentation. The spray boilerplate project has been derived from the excellent template at github that simply works and has elegant code and tests included. After the last mentioned template project worked great, when adding the line import com.typesafe.startscript.StartScriptPlugin to my build.sbt , any sbt command now fails with: /build.sbt:1:

Using Auto Incrementing fields with PostgreSQL and Slick

由 蹲街弑〆低调 提交于 2019-11-29 06:42:04
问题 How does one insert records into PostgreSQL using AutoInc keys with Slick mapped tables? If I use and Option for the id in my case class and set it to None, then PostgreSQL will complain on insert that the field cannot be null.
