@主体中的QueryMap传递参数

Question

我有一个简单的POJO：

class FilterDTO(
    open var page: Int = 0,
    open var size: Int = 20
)

和一个简单的假冒客户端：

@FeignClient(name = "feign-client", url = "\${feign.url.client}")
interface FeignClient{

    @GetMapping("get/{id}")
    fun getById(@PathVariable("id") id: String, @QueryMap(encoded = true) filter: FilterDTO): Any

}

根据拉动请求#667，我期望这被翻译为：

---> GET http://my.service.com/get/123?page=0&size=20 HTTP/1.1
Content-Length: 64
Content-Type: application/json

---> END HTTP (64-byte body)
<--- HTTP/1.1 200 Ok (807ms)
allow: GET

// ...

{"response": "foo"}
<--- END HTTP (108-byte body)

但我得到的是：

---> GET http://my.service.com/get/123 HTTP/1.1
Content-Length: 64
Content-Type: application/json

{"page":0,"size":2}
---> END HTTP (64-byte body)
<--- HTTP/1.1 405 Method Not Allowed (807ms)
allow: GET
cache-control: no-cache, no-store, max-age=0, must-revalidate
//..

{"timestamp":1628783721302,"status":405,"error":"Method Not Allowed","path":"/get/123"}
<--- END HTTP (108-byte body)

请注意，@QueryMap参数在请求主体中传递，而不是作为queryString传递。

它试图调用的endpoint定义为：

    @GetMapping("/get/{id}")
    fun getById(
            @PathVariable("id")
            id: String,
            filter: FilterDTO
    )

我错过了什么？如何使用@QueryMap将其作为查询参数传递？

发现使用spring cloud openfeign我应该使用@SpringQueryMap而不是文档中所述的@QueryMap
