定时推送任务 Apache HttpClient/okhttp3
定时推送任务
需求
需要定时推送我方的数据到对方那边
方法1 Apache HttpClient
此方法指定推送过去的信息转为utf-8格式的json字符串
@Scheduled(initialDelay = 1000 * 120, fixedDelay = 1000 * 60 * 5)
public void diseaseInterface() {String lockKey = "lock:diseaseInterface";String requestId = UUID.randomUUID().toString();boolean acquired = false;try {// 加锁，锁定时间为15分钟acquired = redisTemplate.opsForValue().setIfAbsent(lockKey, requestId, Duration.ofMinutes(15L));if (acquired) {MainBody mainBody = interfaceService.diseaseInterface(new WebServiceBO());if (mainBody != null) {String sendUrl = "对方的接口";// 如果在数据库中配置了接口信息，就从数据库中查询并赋值Code code = codeService.selectByPrimaryKey(DATABASE_CODE_PK_JXZ);if (code != null && StringUtils.isNotEmpty(code.getCode())) {sendUrl = code.getCode();}CloseableHttpClient httpClient = HttpClientBuilder.create().build();HttpPost httpPost = new HttpPost(sendUrl);StringEntity entity = new StringEntity(JSON.toJSONString(mainBody), "utf-8");entity.setContentEncoding("utf-8");entity.setContentType("application/json");httpPost.setEntity(entity);HttpResponse response;try {// 信息推送过去之后，对方会给返回值，结构就是常见的// {// code: 1,//接口返回码，成功0，失败1// msg: '',//提示详细信息，可以为空，可以为中文提示信息// data: {//返回结果对象// }//}// data存放了已经同步过去的id，拿到id，我方这边更新字段，表示该信息已经同步，后续不用再同步response = httpClient.execute(httpPost);JSONObject resultJson = JSON.parseObject(EntityUtils.toString(response.getEntity(), StandardCharsets.UTF_8).trim());if (resultJson != null) {Utils.debug(resultJson.toJSONString());if (200 == resultJson.getInteger("code")) {// 更新字段recSubmitService.updateReportedStateByRecSubId(resultJson.getInteger("data"), STATUS_YES);}}} catch (IOException e) {e.printStackTrace();}}}} finally {// 释放锁Utils.debug("[释放锁]：" + lockKey);if (acquired) {redisTemplate.delete(lockKey);}}
}
方法2 okhttp3
第二个业主也我们需要推送信息过去，按照上面的写法遇到一个报错，
报错信息为
<!DOCTYPE html>

</html>
直接返回了一个网页，看报错信息好像是node报错，不支持utf-8格式，具体怎么解决要看甲方那边调试。
有个现象就是将需要的信息用postman发送过去是正常了，但是写成方法一的代码就出错了，postman支持代码生成，看它提供了 okhttp3 的方法，直接拿来用了
@Scheduled(initialDelay = 1000 * 120, fixedDelay = 1000 * 60 * 5)
public void diseaseInterfaceXC() {String lockKey = "lock:diseaseInterfaceOfXC";String requestId = UUID.randomUUID().toString();boolean acquired = false;try {// 加锁，锁定时间为15分钟acquired = redisTemplate.opsForValue().setIfAbsent(lockKey, requestId, Duration.ofMinutes(15L));if (acquired) {MainBody mainBody = interfaceService.diseaseInterfaceXC(new WebServiceBO());if (mainBody != null) {String sendUrl = "对方的接口";Code code = codeService.selectByPrimaryKey(DATABASE_CODE_PK_XC);if (code != null && StringUtils.isNotEmpty(code.getCode())) {sendUrl = code.getCode();}// 换一种写法，不指定编码格式为utf-8OkHttpClient client = new OkHttpClient().newBuilder().build();MediaType mediaType = MediaType.parse("application/json");RequestBody body = RequestBody.create(mediaType,JSON.toJSONString(WebResponse.ok(mainBody)));Request request = new Request.Builder().url(sendUrl).method("POST", body).addHeader("Content-Type", "application/json").build();Response response = client.newCall(request).execute();String responseBody = response.body().string();ObjectMapper objectMapper = new ObjectMapper();// 用实体类接受返回值ResultVO resultVO = objectMapper.readValue(responseBody, ResultVO.class);if (resultVO.getCode() == 200) {recSubmitService.updateReportedStateByRecSubId(resultVO.getTaskId(), STATUS_YES);}}}} catch (JsonMappingException e) {throw new RuntimeException(e);} catch (JsonProcessingException e) {throw new RuntimeException(e);} catch (IOException e) {throw new RuntimeException(e);} finally {// 释放锁Utils.debug("[释放锁]：" + lockKey);if (acquired) {redisTemplate.delete(lockKey);}}
}
ResultVO
@Data
@AllArgsConstructor
@NoArgsConstructor
public class ResultVO<T> {private Integer code;private Integer taskId;private T msg;
}
