实习内容:
1.定时任务与数据补全:基于 XXL-JOB 实现分布式定时任务调度，补全近半年历史操作日志数据，有效解决因网络异常导致的数据缺失问题。
业务场景；集团的4a日志半年内没有同步，这边需要把日志数据同步到集团上
首先先评估每天的数提量，因为我配照的是开发环境，所有的据量不全，让运维的同事宣询一下每天的数据量是多少?差不多是3.6w日志，那么据总量软是180*3.6=650w号数据知道数据的大概范围认后效开始确认调用天数，循环执行、最终根据实际情况，每15天循环一次，然后添加xx1-job注解。从job平台项用，补全数据朴全过程中断怎么办，可以通过Redis记录处理日期，重启后跳过，同时处理期间增加道暂间隔，减少数据库压大
合井数据库文件
//将操作日志数据同步到4A平台上,根据选取的日期，往前推15天,@XxlJob("syncLog4AJobNew")public void JobHandlerNew() throws IOException {SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");Date curTime = null;Date endTime = null;try {curTime = sdf.parse("2024-12-10 00:00:00");endTime = sdf.parse("2025-05-08 22:00:00");} catch (ParseException e) {throw new RuntimeException(e);}// 每次间隔的时间，单位mslong interval = 24 * 60 * 60 * 1000;int num = 1;while (curTime.before(endTime)) {Date nextTime = new Date(curTime.getTime() + interval);log.info("syncLog4AJobNew-4A日志同步任务:"+nextTime);String curFileName = null;BufferedWriter bufferedWriter = null;try {// 读取需要发的日志数据//List<OperateLogDto> logs = opLogService.queryOperateLog4ANew();List<OperateLogDto> logs = opLogService.queryOperateLog4ANew(nextTime);//填加时间范围log.info("syncLog4AJobNew-4A待发送日志查询成功，获取日志信息数为：" + logs.size());if (CollectionUtils.isEmpty(logs)) {XxlJobHelper.log("无需要同步数据.");curTime = nextTime;//修改continue;}// 写入文件流int length = 0;int startId = 0, endId = 0;for (OperateLogDto logDto : logs) {if (StringUtils.isBlank(logDto.getUserCode()))continue;if (curFileName == null)curFileName = logConfig.getResourceCode() + "_" + new SimpleDateFormat("yyyyMMddHHmmss").format(new Date()) + ".xml";if (bufferedWriter == null) {bufferedWriter = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(ftpConfig.getLocalPath() + curFileName), "UTF-8"));bufferedWriter.write("<?xml version='1.0' encoding='UTF-8' ?><ROOT>");}if (startId == 0)startId = logDto.getOperateLogId();String generateLog = log4AUtil.generateLog(logDto.getToken(), logDto.getOperateLogId().toString(), logDto.getDoneDate(),logDto.getUserCode(), logDto.getOperateTypeName(), logDto.getOperateTypeId(),logDto.getOperateResult(), logDto.getModuleId(), logDto.getModuleName(),logDto.getIp(), logDto.getOperateName());bufferedWriter.write(new String(generateLog.getBytes("UTF-8"), "UTF-8"));endId = logDto.getOperateLogId();// 每个文件控制在5M到10M之间length += generateLog.getBytes(StandardCharsets.UTF_8).length;//当文件长度大于5则传送数据if (length > fileLength) {bufferedWriter.write("</ROOT>");bufferedWriter.flush();// 发送本地文件到4Aboolean ss = this.sendSftp(curFileName);if (ss) {opLogService.updateLog4A(startId, endId);log.info("syncLog4AJobNew-4A日志同步任务成功，上传SFTP成功，传输数据范围为：" + startId + "-" + endId);} else {XxlJobHelper.log("4A日志同步任务失败。上传SFTP失败。");XxlJobHelper.handleFail();return;}// 初始化写入curFileName = null;bufferedWriter = null;length = 0;startId = 0;}}//最后收尾，存在数据没有发送if (bufferedWriter != null) {bufferedWriter.write("</ROOT>");bufferedWriter.flush();// 发送本地文件到4Aboolean ss = this.sendSftp(curFileName);if (ss) {opLogService.updateLog4A(startId, endId);log.info("syncLog4AJobNew-4A日志同步任务成功，上传SFTP成功，传输数据范围为：" + startId + "-" + endId);} else {XxlJobHelper.log("4A日志同步任务失败。上传SFTP失败。");XxlJobHelper.handleFail();}}XxlJobHelper.handleSuccess("4A日志同步任务成功");} catch (Exception e) {log.error("4A日志同步任务失败。" + e);XxlJobHelper.log("4A日志同步任务失败。" + e.getMessage());XxlJobHelper.handleFail();} finally {if (bufferedWriter != null)bufferedWriter.close();}curTime = nextTime;log.info("======SyncLog4AJob.JobHandlerNew()," + num + "," + sdf.format(curTime));num++;}}
2.数据安全与合规控制:通过 SpringAOP 自动脱敏敏感字段，结合 SpringSecurily+ 数据权限注解 实现细粒度访问控制，确保数据隔离与合规性。
