Does @SpringQueryMap Support Multiple Annotations or Nested Objects?

1. Can I use multiple @SpringQueryMap annotations in a single method?

@FeignClient(name = "exampleClient", url = "https://api.example.com")
interface ExampleClient {

    @GetMapping("/example")
    fun search(
        @SpringQueryMap params1: QueryParams,
        @SpringQueryMap params2: QueryParams
    ): String
}

2. Does @SpringQueryMap support nested objects?

data class ParentParam(
    val a: String,
    val child: ChildParam // Nested object
)

data class ChildParam(
    val b: String,
    val c: String
)

@FeignClient(name = "exampleClient", url = "https://api.example.com")
interface ExampleClient {
    @GetMapping("/example")
    fun search(@SpringQueryMap params: ParentParam): String
}

As far as I know, spring-cloud-openfeign does not support either of these.
Why doesn’t spring-cloud-openfeign support them?

If supporting these features does not go against your direction and you have no plans to implement them, would it be okay if I attempt to make the modifications and submit a PR?

The issue identifies @SpringQueryMap and the ExampleClient method signatures as the entry points; start by tracing how those annotations are handled in the repository. Compare current behavior for repeated parameters and nested objects, then establish tests that define the supported behavior before considering implementation.
