Java 編程 訂單、支付、退款、發貨、退貨等編號主動生成類

訂單、支付、退款、發貨、退貨等編號主動生成類

在商城網站中，訂單編號的自動生成，ERP中各個單據的編號自動生成，都可以按照一下的方式來自動生成。

第一步：定義常量訂單編號前綴、訂單編號起始數、訂單編號步長；

 public static final String ORDER_SN_PREFIX = "";// 訂單編號前綴 public static final long ORDER_SN_FIRST = 100000L;// 訂單編號起始數 public static final long ORDER_SN_STEP = 1L;// 訂單編號步長

第二步：定義訂單的最后一個編號號碼；

 public static Long lastOrderSnNumber; //最后的訂單編號號碼

第三步：獲取數據庫中訂單號為最后一個的訂單編號，並賦值給lastOrderSnNumber

// 訂單編號 OrderService orderService = (OrderService) SpringUtil.getBean("orderServiceImpl"); String lastOrderSn = orderService.getLastOrderSn(); if (StringUtils.isNotEmpty(lastOrderSn)) { lastOrderSnNumber = Long.parseLong(StringUtils.removeStartIgnoreCase(lastOrderSn, ORDER_SN_PREFIX)); } else { lastOrderSnNumber = ORDER_SN_FIRST; }

第四步：生成最新的訂單號

/** * 生成訂單編號 * @return 訂單編號 */ public synchronized static String buildOrderSn() { lastOrderSnNumber += ORDER_SN_STEP; return ORDER_SN_PREFIX + lastOrderSnNumber; }

第五步：調用編號生成的方法

order.setOrderSn(SerialNumberUtil.buildOrderSn());

個人一些看法，這些單據編號的自動生成，都是在寫代碼的時候定義好的，以后編號更改形式要是變了呢，是否可以改進，個人覺得應該可以改成配置的形式。

一個完整的類如下，在這里記下，為以后開發用：
