JAVA HTTP请求接受不到参数

发：

List<OrderResListVO> list = optSectMapper.queryOptSect(orderId);
RestTemplate restTemplate = new RestTemplate();
String url = "http://localhost:40011/order/queryCompleteOptSect";
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
MultiValueMap<String, List<String>> map= new LinkedMultiValueMap<>();
List<String> optSect = new ArrayList<>();
for (OrderResListVO vo : list) {
    String resId = vo.getResId();
    optSect.add(resId);
}
map.add("optSectId", optSect);
HttpEntity<MultiValueMap<String, List<String>>> request = new HttpEntity<>(map, headers);
ResponseEntity<OrderResListVO> response = restTemplate.postForEntity( url, request , OrderResListVO.class );
System.out.println(response.getBody());

接：

@PostMapping("/queryCompleteOptSect")
public List<OrderResListVO> queryCompleteOptSect(@RequestParam HttpEntity<MultiValueMap<String, List<String>>> optSectIds){
    System.out.println("进去了");
    return orderService.queryCompleteOptSect(optSectIds);
}

。。。。 接口谁这么写，你要是偷懒直接写map

急用

可以这样试试

@RequestBody Map<String,Object> params
