快速解决code唯一码(java)的简便方法

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！
