how to write regex to match any value in jsonpath for particular key?

Question

I have below the JSON structure. In which I am trying to find the value based on jsonpath.

 {
   "business": {
    "BusinessUnit": "78sdhja",
    "PriorityType": "Scheduled",
    "NoPhiScrubbing": "false"
}
}

Here, I am trying to get the business unit which can have any value like can be empty or null or any value. I have tried with the below example. But it didn't work.

"$.business.[?(@.BusinessUnit== /.*/)]";

Can anyone help me to with this?

If you are working with Spring based project. Go with JSR Validations

https://howtodoinjava.com/spring-mvc/spring-bean-validation-example-with-jsr-303-annotations/

https://beanvalidation.org/1.0/spec/

Above link will help

For Not null or empty you can use @NotNull @Empty while for any value validation you may use pattern for same.

In case value doesn't match, it throws MethodArgumentNotValidException
