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！
