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.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) {
//Rule: Password should contains only a, b and c
Rule rule1 = new AllowedCharacterRule(new char[] {'a', 'b', 'c'});
//8 and 16 characters
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));
}
}
}
