验证密码不包含名称中的3个以上连续字符

问题描述

我需要在Java中进行密码验证后执行此操作

I need to do this following password validation in Java

• 长度必须至少为8个字符


• 必须至少包含1个数字


• 必须至少包含1个大写字母


• 必须包含至少1个小写字母


• 不能包含您的全名或用户名中的3个或更多连续字符（例如，如果您的姓名将您无法获得密码 Stiller458 ）

• Must be at least 8 characters in length
• Must contain at least 1 number
• Must contain at least 1 upper case letter
• Must contain at least 1 lower case letter
• Cannot contain 3 or more consecutive characters from your full name or your username (e.g. If your name is Will you couldn't have the password Stiller458)

我有前4分，我该怎么做最后一个？

I have the first 4 points, how do I do the last one?

目前我有：

String pattern = "^(?=.*[^a-zA-Z])(?=.*[a-z])(?=.*[A-Z])\\S{8,}$";
boolean passwordValidation = originalPassword.matches(pattern);

推荐答案

对于你的1,2,3,4案例

For your 1,2,3,4 case

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

第5例

public boolean isValid(final String userName,final String password)
{
    for(int i=0;(i+2)<userName.length();i++)
          if(password.indexof(userName.substring(i,i+2))!=-1)
                return false;
    return true;
}
