RestTemplate请求发送post请求携带数组参数（亲测有效）

 记得try,catch....................

妈的他们的什么

MultiValueMap<String, String[]> paramMap = new LinkedMultiValueMap<>();可把老子坑惨了

 try {
            //复杂构造函数的使用
            SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();
            requestFactory.setConnectTimeout(10000);// 设置超时
            requestFactory.setReadTimeout(10000);
            //利用复杂构造器可以实现超时设置，内部实际实现为 HttpClient
            RestTemplate restTemplate = new RestTemplate(requestFactory);
            HttpHeaders headers = new HttpHeaders();
            headers.setContentType(MediaType.APPLICATION_JSON_UTF8);
            String[] ids={"8a6980fa762870db01762886a3f50000","8a6980f87626a30601762790871e0002"};
            //设置访问参数
            HashMap<String, Object> params = new HashMap<>();
            params.put("items", ids);
            String url = "http://ip:port/tDeviceInfo/getbyids";
            //设置访问的Entity
            HttpEntity requestEntity = new HttpEntity<>(params, headers);//params 请求体内容, headers请求头内容
            JSONObject jsonObject = iRestTemplate.postForObject(url, requestEntity, JSONObject.class);
            System.out.println(jsonObject);
        }catch (Exception e){
            e.printStackTrace();
        }
