同时使用了hashcode和clone，虽然直接打印对象返回的值是一样的，但是堆地址是不一样的

class ConfigureRevenueAnalysisKey : Cloneable {
    var applicationDate: String = ""

    public override fun clone(): ConfigureRevenueAnalysisKey {
        return super.clone() as ConfigureRevenueAnalysisKey
    }


    override fun hashCode(): Int {
        var hashcode = applicationDate.hashCode() 
        return hashcode
    }

    override fun equals(other: Any?): Boolean {
        val keyOther = (other as ConfigureRevenueAnalysisKey)
        return keyOther.applicationDate == applicationDate
    }
}

object test {
    @JvmStatic
    fun main(strings: Array<String>) {
        val a = ConfigureRevenueAnalysisKey()
        a.applicationDate = "aa"
        val b = a.clone()
        println(a)
        println(b)
        println(b.applicationDate)
        println(a === b)
    }
}

输出:
