vertx LoggerHandler not adding logback

Question

I am trying to use LoggerHandler to log all incoming requests. I am using logback.xml to specify appenders. I am setting system property for logging.

System         


        

Answer 1

I know this question is getting a bit old, but the only way I was able to get the vertx LoggerHandler to not use JUL was to call LoggerFactory.initialise() after setting the system property as described in the question.

Even better, I set the property in my build.gradle, like so:

run {
  systemProperty(
    "vertx.logger-delegate-factory-class-name",
    "io.vertx.core.logging.SLF4JLogDelegateFactory"
  )
  args = ['run', mainVerticleName, "--redeploy=$watchForChange", "--launcher-class=$mainClassName", "--on-redeploy=$doOnChange",
          "-Dvertx.logger-delegate-factory-class-name=io.vertx.core.logging.SLF4JLogDelegateFactory" ]
}

And then at the very top of my MainVerticle::start I have:

LoggerFactory.initialise()

And, boom. Everything is now formatted correctly, including all the startup output.
