Java-如何进行JSON日期验证? [英] Java - How to make JSON date validation?

问题描述

我有这段代码:

@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd")
    protected Date statusDate;

但是出于某种原因，它接受像-

But for somehow it accepts date formats like -

"statusDate": "2017-13-27"

或

"statusDate": "201823-12-12"

是否可以验证请求中的格式(而不是手动验证)?

Is it possible to validate the format within the request (not manually)?

推荐答案

好吧，如果您在截取数据时收到的日期格式不是什么，则需要编写一个自定义的日期序列化/反序列化类，并抛出一个自定义的异常.如您所愿.

Well, you need to write a custom date serialisation/de-serialisation class and throw a custom exception if the date format you receive while intercepting the data is not what you'd expected.

此答案将为您指出正确的方法.

This answer will point you in the right direction of how to do so.

此外，您还可以在代码中包含验证器，以验证有效载荷并使Jackson保持简单状态.

Also you can have the validator in your code to validate the payload and leave Jackson to it's simple state.
