groovy – 仅在if语句中的变量不为null时才测试

def findEvent(String desc,String status = null,Collection events) {
        return events.find {
            it.description == desc && \\If status is not null: it.status == status
        }

        throw new Exception("Review Event Record Not Found: ${desc}")
}

我以为可以这样做,但似乎不起作用：

def findEvent(String desc,Collection events) {
        return events.find {
            it.description == desc && (status != null ?: {it.status == status})
        }

        throw new Exception("Review Event Record Not Found: ${desc}")
}

有什么办法可以做到吗？或者我必须回到这样的事情：

if (status != null) {
    return events.find {
        it.description == desc && it.status == status
    }
} else if (status == null) {
    return events.find {
        it.description == desc
    }
}

有没有一些最佳做法？
