1、调用方式

String url ="http://ip/xxx/zh/xxxxx/xxxx/userCode";
    //进行url中的对应的参数
    url2 =url2.replace("ip",bancirili);
    url2 =url2.replace("zh",zh);
    url2 = url2.replace("userCode",userCode);
    
    String dateTime = xxxx;
    //组装请求体
    String requestBody = "{\"urlParams\":\"?$dateTime=" + dateTime + "\"}";
    //get-发送带body的请求
    Map<String, String> stringStringMap = HttpClientUtils.httpGet(url, requestBody);
    
    //获取请求到的数据，当前为json
    String body = stringStringMap.get("body");
    
    //使用Gson将响应数据转换为实体对象
    Gson gson = new Gson();
    //MqShiftResponse为JSON结构，
    //例如 code，msg，List<MqShift>,此处从MqShiftResponse 解析出MqShift存至List
    MqShiftResponse responseData = gson.fromJson(body,MqShiftResponse.class);
    List<MqShift> shiftList = responseData.getData();

有公司自己的工具类（json转为实体）解析也可以

2、工具类（get发送Body传参-工具类）

public static Map<String, String> httpGet(String url, String requestBody) {
            RequestConfig requestConfig = RequestConfig.custom()
                    .setConnectTimeout(5000) // 设置连接超时时间为5秒
                    .setSocketTimeout(5000) // 设置请求超时时间为5秒
                    .build();
    
            CloseableHttpClient httpClient = HttpClients.createDefault();
            HttpPost httpPost = new HttpPost(url);
            httpPost.setConfig(requestConfig);
    
            httpPost.setEntity(new StringEntity(requestBody, ContentType.APPLICATION_JSON));
    
            Map<String, String> resultMap = new HashMap<>();
            try {
                HttpResponse httpResponse = httpClient.execute(httpPost);
                HttpEntity httpEntity = httpResponse.getEntity();
    
                String body = null;
                int status = 400;
    
                status = httpResponse.getStatusLine().getStatusCode();
                if (null != httpEntity) {
                    body = EntityUtils.toString(httpEntity);
                }
    
                resultMap.put("status", String.valueOf(status));
                resultMap.put("body", body);
    
            } catch (ClientProtocolException e) {
                e.printStackTrace();
                log.error("发送请求失败", e);
                throw new RuntimeException("发送请求失败", e);
            } catch (IOException e) {
                e.printStackTrace();
                log.error("IO异常", e);
                throw new RuntimeException("IO异常", e);
            } finally {
                try {
                    //关闭流，释放资源
                    if (httpClient != null) {
                        httpClient.close();
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            return resultMap;
        }
