Java 编程 订单、支付、退款、发货、退货等编号主动生成类

订单、支付、退款、发货、退货等编号主动生成类

在商城网站中，订单编号的自动生成，ERP中各个单据的编号自动生成，都可以按照一下的方式来自动生成。

第一步：定义常量订单编号前缀、订单编号起始数、订单编号步长；

 public static final String ORDER_SN_PREFIX = "";// 订单编号前缀 public static final long ORDER_SN_FIRST = 100000L;// 订单编号起始数 public static final long ORDER_SN_STEP = 1L;// 订单编号步长

第二步：定义订单的最后一个编号号码；

 public static Long lastOrderSnNumber; //最后的订单编号号码

第三步：获取数据库中订单号为最后一个的订单编号，并赋值给lastOrderSnNumber

// 订单编号 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：生成最新的订单号

/** * 生成订单编号 * @return 订单编号 */ public synchronized static String buildOrderSn() { lastOrderSnNumber += ORDER_SN_STEP; return ORDER_SN_PREFIX + lastOrderSnNumber; }

第五步：调用编号生成的方法

order.setOrderSn(SerialNumberUtil.buildOrderSn());

个人一些看法，这些单据编号的自动生成，都是在写代码的时候定义好的，以后编号更改形式要是变了呢，是否可以改进，个人觉得应该可以改成配置的形式。

一个完整的类如下，在这里记下，为以后开发用：
