Passay 简明教程
Passay − Customized Messages
Passay库提供了一个MessageResolver API，用于覆盖验证程序使用的默认消息。它可以获取自定义属性文件的路径，并使用标准 keys 覆盖所需消息。
Example
以下示例显示了如何使用Passay库验证密码并显示自定义消息。
PassayExample.java
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;
import java.util.Properties;
import org.passay.CharacterRule;
import org.passay.EnglishCharacterData;
import org.passay.LengthRule;
import org.passay.MessageResolver;
import org.passay.PasswordData;
import org.passay.PasswordValidator;
import org.passay.PropertiesMessageResolver;
import org.passay.Rule;
import org.passay.RuleResult;
import org.passay.WhitespaceRule;
public class PassayExample {
public static void main(String[] args) throws FileNotFoundException, IOException {
List<Rule> rules = new ArrayList<>();
rules.add(new LengthRule(8, 16));
rules.add(new WhitespaceRule());
rules.add(new CharacterRule(EnglishCharacterData.UpperCase, 1));
rules.add(new CharacterRule(EnglishCharacterData.LowerCase, 1));
rules.add(new CharacterRule(EnglishCharacterData.Digit, 1));
rules.add(new CharacterRule(EnglishCharacterData.Special, 1));
Properties props = new Properties();
props.load(new FileInputStream("E:/Test/messages.properties"));
MessageResolver resolver = new PropertiesMessageResolver(props);
PasswordValidator validator = new PasswordValidator(resolver, 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));
}
}
}
