例子
下面的示例显示了使用 Passay 库根据上述策略验证密码。
import java.util.ArrayList; import java.util.List; 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) { List<Rule> rules = new ArrayList<>(); //Rule 1: Password length should be in between //8 and 16 characters rules.add(new LengthRule(8, 16)); //Rule 2: No whitespace allowed rules.add(new WhitespaceRule()); //Rule 3.a: At least one Upper-case character rules.add(new CharacterRule(EnglishCharacterData.UpperCase, 1)); //Rule 3.b: At least one Lower-case character rules.add(new CharacterRule(EnglishCharacterData.LowerCase, 1)); //Rule 3.c: At least one digit rules.add(new CharacterRule(EnglishCharacterData.Digit, 1)); //Rule 3.d: At least one special character rules.add(new CharacterRule(EnglishCharacterData.Special, 1)); PasswordValidator validator = new PasswordValidator(rules); 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.
