Scala Slick Driver Logging - scala

Question

I am using the Slick driver with the following versions:
"com.typesafe.slick" %% "slick" % "3.3.1",
"com.typesafe.slick" %% "slick-hikaricp" % "3.3.1"
I have imported these in my class AnimalCounter.scala
import slick.jdbc.PostgresProfile.api._
import slick.jdbc.GetResult
And, I have the following class structure ...
class AnimalCounter {
val db = Database.forConfig("animaldb")
def get(a: Animal): Future[Option[Animal]] =
db.run(....do something......)
def getOrCreate(a: Animal): Future[Option[Animal]] =
db.run(....do something......)
}
So, how do I setup the inbuilt slick logging to log all DB operations that are happening behind the scenes?

Answer 1

Here's the answer on how I got it working. I think #vamsi's approach as mentioned above would work too. However, the important thing to remember in my case was that I needed to remove this dependency since it's designed to supress logs from slick. So please remove this dependency if you already have it.
"org.slf4j" % "slf4j-nop" % "1.7.26"
And after removing the ^^ dependency, please configure your logback.xml like this:
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>[%level] [%date{MM/dd/yyyy HH:mm:ss.SSS}] [SLICK] [%logger{1000}] %green(%X{debugId}) %msg%n</pattern>
</encoder>
</appender>
<root level="${SLICK_LOG_LEVEL:-INFO}">
<appender-ref ref="STDOUT" />
</root>
<logger name="slick.basic.BasicBackend.action" level="${log_action:-inherited}" />
<logger name="slick.basic.BasicBackend.stream" level="${log_stream:-inherited}" />
<logger name="slick.compiler" level="OFF" />
<logger name="slick.compiler.QueryCompiler" level="OFF" />
<logger name="slick.compiler.QueryCompilerBenchmark" level="OFF" />
<logger name="slick.jdbc.DriverDataSource" level="${log_jdbc_driver:-inherited}" />
<logger name="slick.jdbc.JdbcBackend.statement" level="${log_jdbc_statement:-inherited}" />
<logger name="slick.jdbc.JdbcBackend.parameter" level="${log_jdbc_parameter:-inherited}" />
<logger name="slick.jdbc.JdbcBackend.benchmark" level="${log_jdbc_bench:-inherited}" />
<logger name="slick.jdbc.StatementInvoker.result" level="${log_jdbc_result:-inherited}" />
<logger name="slick.jdbc.JdbcModelBuilder" level="${log_createModel:-inherited}" />
<logger name="slick.memory.HeapBackend" level="${log_heap:-inherited}" />
<logger name="slick.memory.QueryInterpreter" level="${log_interpreter:-inherited}" />
<logger name="slick.relational.ResultConverterCompiler" level="${log_resultConverter:-inherited}" />
<logger name="slick.util.AsyncExecutor" level="${log_asyncExecutor:-inherited}" />
</configuration>
