Can't set Content-type for Request Header when use Spring annotations

I’m using Feign and Spring annotations, I have a request that expects to accept “text/plain”.

@PostMapping(value = "/demo", consumes = "application/json", produces="text/plain")
public String demo(@RequestBody List<Long> ids);

But, the produces value not working. The request still has a header: Accept=application/json

I think that when use @RequestBody , the server side should accept the Content-Type = "application/json" request. Here are some of my points:

• when parsing @RequestBody ,it should use handleConsumesAnnotation(data, "application/json"); instead of handleProducesAnnotation(data, "application/json");
• when parsing @ResponseBody ,it should use handleProducesAnnotation(data, "application/json"); instead of handleConsumesAnnotation(data, "application/json");

I can’t say if was fixed or not, feel free to take a look
