If you want to validate that fromDate is before toDate, you can write a custom validator to perform this multi-field validation. You write a custom validator, and you also define a custom annotation which is placed on the bean being validated.
如果要验证 fromDate 是否在 toDate 之前，可以编写自定义验证器来执行此多字段验证。您编写了一个自定义验证器，并且还定义了一个放置在要验证的 bean 上的自定义注释。

For sure you can use Bean Validation inside your controller, just add an annotation on the property like you did in your model. But the best way would be use a Date type in your model instead of string.
确保您可以在控制器中使用 Bean 验证，只需像在模型中一样在属性上添加注释即可。但最好的方法是在模型中使用 Date 类型而不是字符串。
