Hi,

a few years ago, the initial feature request was created to allow setting the null handling via the 'sort' query parameters.

In the mean time, this was picked up by jakartaee/persistence (jakartaee/persistence#76) and, as far as I can tell, there is progress made in getting this into spring-data-jpa for 3.4.0.

Following addition to the @SortDefault annotation could be made:

@SortDefault(
 value = "property",
 direction = Sort.Direction.DESC,
 nullHandling = Sort.NullHandling.NULLS_LAST
)

Following addition to the sort query param could be made:
?sort=(propertyName)+(,ASC|,DESC)?(,ignorecase)?(,nullsnative|,nullsfirst|,nullslast)?

The null handling would be optional, and work in any combination with the remaining, optional parameters. A few, valid examples would be:

?sort=property1
?sort=property1,property2,nullsfirst
?sort=property1,asc,nullslast
?sort=property1,property2,desc,ignorecase,nullsnative

As the SortHandlerMethodArgumentResolverSupport is part of spring-data-commons, I opted to create the issue here again to have an issue number in this project, hope this was the right approach.

Edit: A draft PR implementing the suggestion can be found here: #3153. Happy to hear any suggestions you might have!
