postForEntity传递List参数_postforentity传参

1. 发送端
HttpHeaders headers = new HttpHeaders();
headers.add("Authorization", token);        // 可有可无
HttpEntity<List<String>> httpEntity = new HttpEntity<>(list, headers);
String url = path + "/pict/getPica";
JSONObject resultObject = restTemplate.postForEntity(url, httpEntity, JSONObject.class).getBody();

2. 接收端: 

@PostMapping("/pict/getPica")
public ResponseData<JSONObject> getPica(@RequestBody List<String> list) {}

注意, 不能设置 :

headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

否则会失败.

亲测有效可行.
