Passay - AllowedRegexRule

AllowedRegexRule 允许指定密码应满足的正则模式。请考虑以下示例。

Example

以下示例显示了使用 Passay 库根据上述策略对密码进行验证的过程。

import org.passay.AllowedRegexRule;
import org.passay.LengthRule;
import org.passay.PasswordData;
import org.passay.PasswordValidator;
import org.passay.Rule;
import org.passay.RuleResult;

public class PassayExample {
   public static void main(String[] args) {
      //Rule: Password should contains alphabets only
      Rule rule1 = new AllowedRegexRule("^[A-Za-z]+$");
      //8 and 16 characters
      Rule rule2 = new LengthRule(8, 16);

      PasswordValidator validator = new PasswordValidator(rule1, rule2);
      PasswordData password = new PasswordData("microsoft@123");
      RuleResult result = validator.validate(password);

      if(result.isValid()){
         System.out.println("Password validated.");
      } else {
         System.out.println("Invalid Password: " + validator.getMessages(result));
      }
   }
}

Output

Invalid Password: [Password must match pattern '^[A-Za-z]+$'.]
