restTemplate 踩坑

HttpHeaders httpHeaders = new HttpHeaders(); 设置请求头

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

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

ResponseEntity<Map> exchange = restTemplate.exchange("url", HttpMethod.PUT, requestEntity, Map.class);
踩坑 获取body的值时 是一个数组类型  报错 500 服务器内部错误
可发测试日志 打印log 查看 传参数接收格式

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