我想向服务器发布一个InputStream，我使用Spring和RestTemplate来执行我的HTTP请求。
委托方

public void postSomething(InputStream inputStream) {
          String url = "localhost:8080/example/id";
          RestTemplate restTemplate = new RestTemplate();
          restTemplate.getMessageConverters().add(new ByteArrayHttpMessageConverter());
          restTemplate.postForLocation(url, inputStream, InputStream.class); 
    }

伺服器

@PostMapping("/example/{id}")
public void uploadFile(@RequestBody InputStream inputStream, @PathVariable String id) { 
           InputStream inputStream1 = inputStream;
}

在客户端得到No HttpMessageConverter for [java.io.ByteArrayInputStream]，在服务器端得到Cannot construct instance of 'java.io.InputStream' (no Creators, like default constructor, exist): abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information
