Question

Slick用大量的日志消息填满了控制台。我希望像文档建议一样使用slf4j-nop，因此关闭日志记录，但Akka需要自己的slf4j库。

所以我离开了Slick也使用的akka-slf4j_2.10。我尝试了很多东西。我的application.conf中包含此内容（尝试使用和不使用＆＃34;）：

logger="OFF"
logger.scala.slick="OFF"
logger.scala.slick.session="OFF"
logger.scala.slick.jdbc.JdbcBackend.statement="OFF"
logger.scala.slick.jdbc="OFF"

它没有效果。有人可以帮我关掉这个日志，这样我就可以再次喜欢Slick吗？

我得到的一些日志消息：

17:16:56.706 [seating-akka.actor.default-dispatcher-8] DEBUG scala.slick.ast.Node$ - Assigned type Int/INTEGER to node InsertColumn SEAT_ID

17:16:56.710 [seating-akka.actor.default-dispatcher-8] DEBUG scala.slick.compiler.QueryCompiler - After phase insertCompiler:

我通过向logback.xml添加src/main/resources来修复它：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <logger name="scala.slick" level="INFO" />
</configuration>

我发现了somewhere in a Github project。

您是否尝试在application.conf中关闭akka日志记录？

akka {
  stdout-loglevel = "OFF"
  loglevel = "OFF"
}

参见＆＃34;关闭记录＆＃34; documentation中的部分。

给定here的logback.xml文件解决了我的问题。

上述步骤不起作用的最常见原因是因为未读取xx.xml logback文件。检查它是否在正确的类路径中。

xx.xml文件中唯一需要更改光滑日志记录级别的设置是：

<logger name="slick"  level="INFO" />

如果是sbt ，如果资源文件夹不在src / main下，则可以按如下方式提及路径：

resourceDirectory in Compile := baseDirectory.value / "conf"

当sbt程序集完成时，它会将logback配置文件转储到fat jar

如果从jar

运行

java -Dlogback.configurationFile=dev-logger.xml -Dfile.ending=UTF8  -cp $SCALA_HOME/lib/scala-library.jar  -jar myProject.jar -Dconfig.file=application.conf

如果来自Intellij，请确保将包含dev-logger.xml等logback conf文件的文件夹标记为resources文件夹。如果配置文件是logback.xml，则默认情况下需要在运行配置中的VM设置中提及它
