如下所示：

public String next() { long appBootTimes = systemVariableService.getAppBootTimes(); return Long.toString(appBootTimes * 10000000000000000l + seq.incrementAndGet(), Character.MAX_RADIX);}

解释：找数据库中的最近新增的账号

public String nextNo() { return Long.toString(seq.incrementAndGet());}　public String nextTradeNo() { return "T" + LocalDate.now().format(DateTimeFormatter.ofPattern("uuuuMMdd")) + next(); }　　public String nextFileName(String suffix) { return LocalDate.now().format(DateTimeFormatter.ofPattern("uuuuMMdd")) + "/" + UUID.randomUUID() + (StringUtils.isNotBlank(suffix) ? ("." + suffix) : ""); }public String nextPurchaseNo(){ return "PO"+LocalDate.now().format(DateTimeFormatter.ofPattern("yyyyMMdd")) + "-" + systemVariableService.getPurchaseNumbers("PO"); }　public String nextSalesNo(){ System.out.println(systemVariableService.getSalesNumbers("SO")); return "SO"+LocalDate.now().format(DateTimeFormatter.ofPattern("yyyyMMdd")) + "-" + systemVariableService.getSalesNumbers("SO"); }　public String nextReceiptNo(){ return "SI"+LocalDate.now().format(DateTimeFormatter.ofPattern("yyyyMMdd")) + "-" + systemVariableService.getReceiptNumbers("SI"); }　public String nextLoadingListNo(){ return "LL"+LocalDate.now().format(DateTimeFormatter.ofPattern("yyyyMMdd")) + "-" + systemVariableService.getLoadingListNumbers("LL"); }　public String nextDeliverNo(){ return "DL"+LocalDate.now().format(DateTimeFormatter.ofPattern("yyyyMMdd")) + "-" + systemVariableService.getDeliverNumbers("DL"); }　public String nextOtherInNo(){ return "OI"+LocalDate.now().format(DateTimeFormatter.ofPattern("yyyyMMdd")) + "-" + systemVariableService.getOtherInNumbers("OI"); }public String nextOtherOutNo(){ return "OO"+LocalDate.now().format(DateTimeFormatter.ofPattern("yyyyMMdd")) + "-" + systemVariableService.getOtherOutNumbers("OO"); }　public String nextPromotionNo(){ return "HD"+LocalDate.now().format(DateTimeFormatter.ofPattern("yyyyMMdd")) + "-" + systemVariableService.nextPromotionNo("HD"); }　　public String nextBalanceFeeNo() { return "FT" + systemVariableService.getBalanceFeeNumbers(); }

以上的方法,都比较的好用和方便。其实这些我都要百度，是同事写的，真强！
