A password contains at least eight characters, including at least one number and includes both lower and uppercase letters and special characters, for example#,?密码至少包含八个字符，包括至少一个数字，并且同时包含大小写字母和特殊字符，例如#?,!，!.。

You may use this regex with multiple lookahead assertions (conditions) :您可以将此正则表达式与多个先行断言（条件）一起使用 ：
^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,}$
This regex will enforce these rules:此正则表达式将执行以下规则：
At least one upper case English letter ,(?=.*?[AZ])至少一个大写英文字母 ，(?=.*?[AZ])At least one lower case English letter,(?=.*?[az])至少一个小写英文字母(?=.*?[az])At least one digit,(?=.*?[0-9])至少一位数字(?=.*?[0-9])At least one special character,(?=.*?[#?!@$%^&*-])至少一个特殊字符(?=.*?[#?!@$%^&*-])Minimum eight in length.{8,}(with the anchors)长度最少为八位.{8,}（带锚点）

Just a small improvement for @anubhava's answer: Since special character are limited to the ones in the keyboard, use this for any special character:@anubhava的答案仅作一个小改进：由于特殊字符仅限于键盘上的字符，因此可将其用于任何特殊字符：
^(?=.*?[AZ])(?=(.*[az]){1,})(?=(.*[\\d]){1,})(?=(.*[\\W]){1,})(?!.*\\s).{8,}$
This regex will enforce these rules:此正则表达式将执行以下规则：
At least one upper case English letter至少一个大写英文字母At least one lower case English letter至少一个小写英文字母At least one digit至少一位数字At least one special character至少一个特殊字符Minimum eight in length长度最少八位

I had some difficulty following the most popular answer for my circumstances.对于我的情况，我在遵循最受欢迎的答案时遇到了一些困难。For example, my validation was failing with characters such as;例如，我的验证失败，例如字符;or[.或[。I was not interested in white-listing my special characters, so I instead leveraged[^\\w\\s]as a test - simply put - match non word characters (including numeric) and non white space characters.我对将特殊字符列入白名单不感兴趣，因此我利用[^\\w\\s]作为测试-简而言之-匹配非单词字符（包括数字）和非空格字符。To summarize, here is what worked for me...总而言之，这是对我有用的...
at least8characters至少8字符at least1numeric character至少1数字字符at least1lowercase letter至少1个小写字母at least1uppercase letter至少1大写字母at least1special character至少1特殊字符
/^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[^\w\s]).{8,}$/
