关闭 Slick 注销

Question

Slick 用大量的日志消息填满了控制台。就像文档中建议的那样，我想使用slf4j-nop，因此关闭了日志记录，但 Akka 需要自己的 slf4j 库。

所以我留下了 Slick 也使用的 akka-slf4j_2.10。我已经尝试了很多东西。我的application.conf 中包含这个（尝试使用和不使用“）：

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

它的影响为零。 有人可以帮我关闭此注销功能，以便我再次喜欢 Slick 吗？

我收到的一些日志消息：

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:

我已通过将logback.xml 添加到src/main/resources 来修复它：

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

我找到了这个somewhere in a Github project。

here 给出的 logback.xml 文件解决了我的问题。

您是否尝试过关闭 application.conf 中的 akka 登录？

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

请参阅documentation 中的“关闭日志记录”部分。

Answer 4

上述步骤不起作用的最常见原因是您的 xx.xml logback 文件未被读取。检查它是否在正确的类路径中。

在 xx.xml 文件中更改 slick 日志记录级别所需的唯一设置是：

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

如果是 sbt，如果资源文件夹不在 src/main 下，路径可以如下提及：

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

当 sbt 组装完成后，它会将 logback 配置文件转储到 fat jar 中

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，请确保包含 logback conf 文件（如 dev-logger.xml）的文件夹被标记为资源文件夹。如果配置文件是 logback.xml，它会默认使用，否则你需要在运行配置的 VM 设置中提及它
