Passay − 自定义消息

Passay 库提供了一个 MessageResolver API 来覆盖验证器所使用的默认消息。它可以找到自定义属性文件的路径，并且使用标准 键 来覆盖所需消息。

示例

以下示例显示使用 Passay 库验证密码以及显示自定义消息。

messages.properties

INSUFFICIENT_UPPERCASE=Password missing at least %1$s uppercase characters.

      Properties props = new 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));            
      }

}
