推荐答案

应该这样做:

(?=.*?[a-z])(?=.*?[A-Z])(?=.*?[^a-zA-Z]).{8,}

参见此处:rubular

说明:

(?=.*?[a-z]) //lookahead, there has to be a lower case alphabetic char
(?=.*?[A-Z]) //lookahead, there has to be a upper case alphabetic char
(?=.*?[^a-zA-Z]) //lookahead, there has to be a non-alphabetic char
.{8,} // any character at least 8 times
