以前写了一个java的正规表达式的java工具类,分享一下,有用到的欢迎下载使用。
如果你有常用的定义好的,且测试通过的正规表达式,欢迎跟贴,也让我享用一下 .
类中用到了 jakarta-oro-2.0.jar 包,请大家自己在 apache网站下下载
在这是junit测试单元类我就不提交了,在main()方法中有几个小测试,有兴趣自己玩吧.
这个工具类目前主要有25种正规表达式(有些不常用,但那时才仔细深入的研究了一下正规,写上瘾了,就当时能想到的都写了):
1.匹配图象; 2 匹配email地址; 3 匹配匹配并提取url ; 4 匹配并提取http ;
5.匹配日期 6 匹配电话; 7 匹配身份证 8 匹配邮编代码
9. 不包括特殊字符的匹配 (字符串中不包括符号 数学次方号^ 单引号' 双引号" 分号; 逗号, 帽号: 数学减号- 右尖括号> 左尖括号< 反斜杠\ 即空格,制表符,回车符等
10 匹配非负整数(正整数 + 0) 11 匹配不包括零的非负整数(正整数 > 0)
12 匹配正整数 13 匹配非正整数(负整数 + 0)
14 匹配负整数; 15. 匹配整数 ;
16 匹配非负浮点数(正浮点数 + 0) 17. 匹配正浮点数
18 匹配非正浮点数(负浮点数 + 0) 19 匹配负浮点数;
20 .匹配浮点数; 21. 匹配由26个英文字母组成的字符串;
22. 匹配由26个英文字母的大写组成的字符串 23 匹配由26个英文字母的小写组成的字符串
24 匹配由数字和26个英文字母组成的字符串; 25 匹配由数字、26个英文字母或者下划线组成的字符串;
