Passay - AllowedCharacterRule

AllowedCharacterRule 允许指定密码可以包含的字符。请考虑以下示例。

示例

以下示例显示了使用 Passay 库根据上述策略验证密码。

import org.passay.AllowedCharacterRule;
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) {
      //规则:密码只能包含 a、b 和 c       
      Rule rule1 = new AllowedCharacterRule(new char[] {'a', 'b', 'c'});
      //8 和 16 个字符
      Rule rule2 = new LengthRule(8, 16);    

      PasswordValidator validator = new PasswordValidator(rule1, rule2);
      PasswordData password = new PasswordData("abcabcab1");
      RuleResult result = validator.validate(password);

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

输出

Invalid Password: [Password contains the illegal character '1'.]
