restTemplate 踩坑

HttpHeaders httpHeaders = new HttpHeaders(); 設置請求頭

MultiValueMap<String, String> requestBody = new LinkedMultiValueMap<>(); 設置body

HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<>(requestBody, httpHeaders); 

ResponseEntity<Map> exchange = restTemplate.exchange("url", HttpMethod.PUT, requestEntity, Map.class);
踩坑 獲取body的值時 是一個數組類型  報錯 500 服務器內部錯誤
可發測試日志 打印log 查看 傳參數接收格式

protected final org.slf4j.Logger LOGGER = LoggerFactory.getLogger(this.getClass());
