我正在研究正则表达式，但不知道该做些什么。
这些是我的正则表达式：
1）{
"created_by": "Administrator IIS",

2）"^-?\\d{1,3}(?:\\.\\d{3})*(?:,\\d+)?\\s$";
3）"^-?\\d{1,3}(?:\\.\\d{3})*(?:,\\d+)?\\s\\€$"
4）"[0-9.,]*"
这些正则表达式检查货币字符串或数字。
每一个例子
1）123.456,99
2）123.456,99€
3）12,19
4）12,19€
每个正则表达式都适用于相关示例。 是否可以将所有正则表达式合并为一个？ 如何使这个正则表达式灵活地适应该字符串中任何位置的空格。
事先提前萨米
答案 0 :(得分：2)
您可以使用^-?(\d{1,3}\s*?([.,]|$|\\s)\\s*?)+€?$
^-?(\\d{1,3}\\s*?([.,]|$|\\s)\\s*?)+€?$：^以
(\\d{1,3}\s*?([.,]|$|\\s)\\s*?)+匹配一对或多对数字，由.或, \\d{1,3}\\s*?匹配1到3之间的数字，尽可能少地匹配空格([.,]|$|\s)\\s*?零个或一个匹配.或,或结束或空格，\\s*?零个或多个空格 €?$ €个字符的零或一个匹配，$匹配结束
答案 1 :(得分：0)
这应该可以解决问题
\d{1,3}(?:.|,)+€?
对于java，它应该是"\\d{1,3}(?:.|,)+€?"
我强烈建议http://regexr.com满足您的所有正则表达式需求。他们有一个很棒的“cheatsheet”和一个不错的测试环境
