Filter nested Object property uisng @JsonFilter

Question

I have gone through many StackOverflow's questions and github's issues, but didn't get the solution of my problem. I have class as follow :

@JsonFilter("apiFilter")
Class Employee{
    String id,
    String name;
    Address address,
}
@JsonFilter("apiFilter")
Class Address{
    String id,
    String city,
    String state,
    String country,
}

I want to filter the properties of Employee and its nested object Address properties using @JosnFilter while returning the response of API, where I am able to filter the properties of Employee with below set of codes

SimpleBeanPropertyFilter propertyFilter = SimpleBeanPropertyFilter.filterOutAllExcept("name", "address");
        
FilterProvider filters = new SimpleFilterProvider().addFilter("apiFilter", propertyFilter).setFailOnUnknownId(false);

But I need to filter the properties of nested object also using dot(.) For example "address.city" and "address.state" will be passed in filterOutAllExcept("address.state","address.city") . I could not use a different filter for address as I need to filter property based on object reference dot(.) its properties like address.state

I have gone through these github issues but there is no recent update on the support of nested object properties by jackson.

https://github.com/FasterXML/jackson-core/issues/230

https://github.com/FasterXML/jackson-databind/issues/1040

https://github.com/spring-projects/spring-framework/issues/17187

Any suggestion would be a great help.. Thanks.
