1、发送请求

• 查询出数据
• 封装参数
• 发送请求
• 处理响应结果

@RequestMapping(value="/updateTodoInfo",method = {RequestMethod.POST})
public void sendPostRequest() {try {URL url = new URL("http://ip:8080/test");List<TodoEntity> dataList=flowInformationService.selectAllTodoInfo();;List<List<TodoEntity>> idsPartition = Lists.partition(dataList, 15);LocalDateTime now = LocalDateTime.now();DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMddHHmmss");String formattedDateTime = now.format(formatter);for (List<TodoEntity> list : idsPartition) {HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setRequestMethod("POST");connection.setRequestProperty("Content-Type", "application/json");connection.setDoOutput(true);// 构造JSON数据JSONArray jsonArray = new JSONArray();for (TodoEntity data : list) {JSONObject jsonObject = new JSONObject();jsonObject.put("pendingCode", data.getPendingCode());jsonObject.put("pendingStatus", "0");jsonObject.put("lastUpdateDate", formattedDateTime);jsonObject.put("pendingURL", data.getPendingURL());jsonObject.put("pendingNote", "test");jsonArray.put(jsonObject);}String jsonString = jsonArray.toString();// 发送数据try (OutputStream os = connection.getOutputStream()) {byte[] input = jsonString.getBytes(StandardCharsets.UTF_8);os.write(input, 0, input.length);}int responseCode = connection.getResponseCode();System.out.println("Response code: " + responseCode);connection.disconnect();Thread.sleep(600);}} catch (Exception e) {e.printStackTrace();}
}

2、实体类

public class TodoEntity {private String pendingCode;private String pendingURL;public String getPendingCode() {return pendingCode;}public void setPendingCode(String pendingCode) {this.pendingCode = pendingCode;}public String getPendingURL() {return pendingURL;}public void setPendingURL(String pendingURL) {this.pendingURL = pendingURL;}
}
