How to prevent Akka LoggingAdapter from truncating ByteString log messages?-CodePudding

I'm new to Scala with Akka. I'm using LoggingAdapter to log ByteString messages. I see a common scenario where a decently large message gets truncated. For example,

I need to see the entire message. Please help me here.

This is because of the logic in akka.util.ByteString.toString method:

override def toString(): String = {
    val maxSize = 100
    if (size > maxSize)
      take(maxSize).toString   s"... and [${size - maxSize}] more"
    else
      super.toString
  }

you can convert ByteString to List and this will print everything.

val myBs: ByteString = ??? //some very long ByteString
println(myBs) //this will get truncated
println(myBs.toList) //but this will not

We can convert the ByteString to an array and then print the individual bytes in a space-separated manner.

val myArr : Array[Byte] = byteStringMessage.toArray
log.info(s" byte array : ${myArr.mkString(" ")}")
