本文介绍了一种订单编号自动生成的方法，包括定义常量、获取最后一个订单编号并生成新的订单编号等步骤，适用于商城网站和ERP系统。

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：

package net.shopxx.util;
import java.util.UUID;
import net.shopxx.service.OrderService;
import net.shopxx.service.PaymentService;
import net.shopxx.service.RefundService;
import net.shopxx.service.ReshipService;
import net.shopxx.service.ShippingService;
import org.apache.commons.lang3.StringUtils;

 public static final long ORDER_SN_STEP = 1L;// 订单编号步长
 
 public static final String PAYMENT_SN_PREFIX = "";// 支付编号前缀
 public static final long PAYMENT_SN_FIRST = 100000L;// 支付编号起始数
 public static final long PAYMENT_SN_STEP = 1L;// 支付编号步长
 
 public static final String REFUND_SN_PREFIX = "";// 退款编号前缀
