Passay - NumberRangeRule

NumberRangeRule允许指定密码中不允许的数字范围。考虑以下示例。

例子

import org.passay.IllegalCharacterRule;
import org.passay.NumberRangeRule;
import org.passay.PasswordData;
import org.passay.PasswordValidator;
import org.passay.RuleResult;
import org.passay.WhitespaceRule;

public class PassayExample {
   public static void main(String[] args) {
      //Rule: Special characters like &, <, > are not allowed in a password 
      IllegalCharacterRule illegalCharacterRule 
         = new IllegalCharacterRule(new char[] {'&', '<', '>'});

      //Rule: 1 to 5 numbers are not allowed
      NumberRangeRule numberRangeRule = new NumberRangeRule(1, 5);

      //Rule: White spaces are not allowed
      WhitespaceRule whitespaceRule = new WhitespaceRule();

      PasswordValidator validator 
         = new PasswordValidator(illegalCharacterRule,numberRangeRule,whitespaceRule);
      PasswordData password = new PasswordData("abc&4d  ef6");
      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 '&'.,
Password contains the number '4'.,
Password contains a whitespace character.]
