Passay - CharacterCharacteristicsRule

CharacterCharacteristicsRule 有助于定义密码是否满足给定的 N 条定义规则。

示例

以下示例显示了使用 Passay 库根据上述策略验证密码。

import java.io.FileNotFoundException;
import java.io.IOException;

import org.passay.CharacterCharacteristicsRule;
import org.passay.CharacterRule;
import org.passay.EnglishCharacterData;
import org.passay.LengthRule;
import org.passay.PasswordData;
import org.passay.PasswordValidator;
import org.passay.Rule;
import org.passay.RuleResult;
import org.passay.WhitespaceRule;

public class PassayExample {
   public static void main(String[] args) throws FileNotFoundException, IOException {
        //规则 1:密码长度应介于
        //8 和 16 个字符之间
        Rule rule1 = new LengthRule(8, 16);
        //规则 2:不允许有空格
        Rule rule2 = new WhitespaceRule();
        CharacterCharacteristicsRule rule3 = new CharacterCharacteristicsRule();
        //M - 强制字符数
        rule3.setNumberOfCharacteristics(3);
        //规则 3.a:一个大写字符
        rule3.getRules().add(new CharacterRule(EnglishCharacterData.UpperCase, 1));
        //规则 3.b:一个小写字符
        rule3.getRules().add(new CharacterRule(EnglishCharacterData.LowerCase, 1));
        //规则 3.c:一位数字
        rule3.getRules().add(new CharacterRule(EnglishCharacterData.Digit, 1));
        //规则 3.d:一个特殊字符
        rule3.getRules().add(new CharacterRule(EnglishCharacterData.Special, 1));
        
        PasswordValidator validator = new PasswordValidator(rule1, rule2, rule3);        
        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));            
        }
   }
}

输出

Password validated.
