Move recurring @RequestParams somewhere before Controller

Question

I have multiple endpoints in my RestControllers that follow some similar signature:

@GetMapping
public SomeItem get(@RequestParam String sortBy, 
                    @RequestParam String sortField, 
                    @RequestParam int pageNumber,
                    @RequestParam int pageSize) {
  QueryOptions queryOptions = QueryOptions.of(sortyBy, sortField, pageNumber, pageSize);
  // ...
}

I was wondering if there is a way of removing this code duplication from all the different methods and move the QueryOptions construction somewhere before the RestController method, so that I could use a method like the following:

@GetMapping
public SomeItem get(QueryOptions queryOptions) {
  // ...
}

How can I do this? Maybe adding a filter in the filterchain?

Answer 1

It turns out that this is supported out of the box:

@Getter
@Setter
public class QueryOptions {
  private String pageNumber;
  private String pageSize;
  private String orderBy;
  private String sortField;
}

And then you can accept this Class in the Controller method:

@GetMapping
public SomeItem get(QueryOptions queryOptions) {
  // ...
}
