javax.el.PropertyNotFoundException: 使用 TypeSafe 找不到 HibernateValidator 的 属性 长度
javax.el.PropertyNotFoundException: Cannot find property length for HibernateValidator using TypeSafe
我正在寻找开发的 Spring MVC + spring data jpa + Hibernate Validator 集成示例。在这个项目中，我面临以下问题。在我看来，messages_en.properties 文件未正确加载，导致以下失败。
我知道在堆栈溢出时已经提出了类似的问题，但是 none 解决方案对我有用。

您永远不应该使用 $ 作为占位符。只需使用以下代码。这将解决您的错误：

@SafeHtml(whitelistType=WhiteListType.NONE, message="{html.validation.firstName}")

您永远不应该使用 $ 作为占位符。只需使用以下代码。这将解决您的错误：
