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。
Passay libary provides a MessageResolver API to override the default messages used by the validator. It can take the path to custom properties file and use the standard keys to override the required message.
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。
