示例1: encode
//设置package包名称以及导入依赖的类
package com.ox.bigdata.util.kafka
import kafka.common.KafkaException
import kafka.utils.Logging
import scala.collection.{Iterable, Map}
import scala.util.parsing.json.JSON
def encode(obj: Any): String = {
obj match {
case null => "null"
case b: Boolean => b.toString
case s: String => "\"" + s + "\""
case n: Number => n.toString
case m: Map[_, _] =>
"{" +
m.map(elem =>
elem match {
case t: Tuple2[_, _] => encode(t._1) + ":" + encode(t._2)
case _ => throw new IllegalArgumentException("Invalid map element (" + elem + ") in " + obj)
}).mkString(",") +
"}"
case a: Array[_] => encode(a.toSeq)
case i: Iterable[_] => "[" + i.map(encode).mkString(",") + "]"
case other: AnyRef => throw new IllegalArgumentException("Unknown arguement of type " + other.getClass + ": " + other)
}
}
