Question

求助一个freemarker中replace使用正则的问题

Answer 1

可以只使用replace实现的替换字符串 replace
${s?replace(‘ba’, ‘XY’ )}
${s?replace(‘ba’, ‘XY’ , ‘规则参数’)}将s里的所有的ba替换成xy 规则参数包含: i r m s c f 具体含义如下:
· i: 大小写不区分.
· f: 只替换第一个出现被替换字符串的字符串
· r: XY是正则表达式
· m: Multi-line mode for regular expressions. In multi-line mode the expressions ^ and $ match just after or just before, respectively, a line terminator or the end of the string. By default these expressions only match at the beginning and the end of the entire string.
· s: Enables dotall mode for regular expressions (same as Perl singe-line mode). In dotall mode, the expression . matches any character, including a line terminator. By default this expression does not match line terminators.
· c: Permits whitespace and comments in regular expressions.
