Cannot render primitive wrapper with @ParameterObject

[voduku]

Describe the bug
When I use this method signature:
@PostMapping()
public void create(@ParameterObject Long id, @RequestBody Object o)
I get java.lang.StackOverflowError

To Reproduce
I use the latest version of springdoc and no additional configuration than default.

Expected behavior
For spring, it will be able to pick up the query param and correctly map it to Long class.

Expected Swagger page:
Show page with query param id that map to Long class

expected generated URL: http://host/?id=1
body: {}

Screenshots
Truncated unnecessary log.

@VuDo98,

The usage of @ParameterObject is wrong. This annotation extracts fields from parameter object.
You should simply use @Parameter swagger standard annotation instead, or mark the parameter explicitly as @RequestParam.

	@PostMapping(value = "/persons")
	public void create(@Parameter(in = ParameterIn.QUERY) Long id, @RequestBody Object o){}

I have added control to prevent this error on bad usage of @ParameterObject annotation.

Additionally, with the next release, it will be detected out of the box, without any extra swagger-annotations.

@bnasslahsen I raised this issue because I actually use generic there instead of Long. Some entity have a composite key which works here. Some only have a auto generated Long id. But I guess it is considered bad usage so I use some the customizer to fill out the blanks

[voduku]

@bnasslahsen tbh, I wonder why there is @ParameterObject. Isn't it possible to convert the POJO to query params since spring is doing it already? Objects without any annotation are auto-mapped to query params
