Groovy用唯一的数字替换字符串中的一个特定单词

用给定字符串中的唯一数字替换每个单词nullnull

每次更换都应该是唯一的编号。时间戳，如果可能的话

为了教学，我给大家举了以下例子。首先，因为它是groovy，所以不必有类和主方法。第二，这不是最理想的方法，但它是一个很好的例子。第三，您可以尝试将时间戳的格式设置为只包含秒或您喜欢的内容。如果希望行中的每个nullnull都有不同的tstamp，则必须尝试使用例如.splitEachLine循环行中的值

也可以考虑在源代码中清除数据，如果是在控件中。

下面是一个例子：

def data = '''AMOUNTUSTOMNOTESRKNOTESY,AMOUNTURRNOTESNAMOUNTYAMOUNTOPAYMNOTESNTMNOTESTHODNOTES,AMOUNT,PAYMNOTESNTMNOTESTHOD,NOTES,BankTransDate,BanktransRef,

通常，人们会显示他们试图解决问题的代码。不尝试就要求解决方案不是最好的方式。我已经添加了代码。感谢您的快速更新。非常感谢你的努力。在这里，我们尝试了.splitEachLine，data.readLines.splitEachLine，获取错误，如>>捕获的：groovy.lang.MissingMethodException:方法java.util.ArrayList.splitEachLine的签名不适用于参数types@Marc替换时我没有得到唯一的号码。使用splitline cmd
