在某些涉及交易的系统中常常会用到不同币种，所以我总结了全球各国的货币编码为几种使用方式。
1.数据库形式
数据库形式可以在系统初始化时加载，也可以加载到缓存中使用，这种方式比较灵活，可以与其他表结合使用，如：order，pay等，结构如图：
建表语句为：
CREATE TABLE `currency` ( `CURRENCY_ID` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '主键', `CURRENCY_CODE` varchar(8) NOT NULL COMMENT '币种', `VERSION` int(11) DEFAULT '0', `CREATE_DATE` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建日期', `TYPE` int(2) DEFAULT '0' COMMENT '类型', `STATUS` int(2) DEFAULT '0' COMMENT '状态', `NAME` varchar(32) NOT NULL COMMENT '名称', `ENGLISH_NAME` varchar(64) DEFAULT NULL COMMENT '英文名', PRIMARY KEY (`CURRENCY_ID`) ) ENGINE=InnoDB AUTO_INCREMENT=173 DEFAULT CHARSET=utf8 COMMENT='币种';
随后插入相应币种信息即可，所有币种信息在本文附件中。
2.枚举形式
枚举形式的好处在于可以在程序中快速转换与判断，可以封装成相关工具类使用，以下是源码：
package com.rm.base.common.enums;

3.使用Java.util.Currency类
Currency是util包下的货币实现，使用它可以做很多事情，所以在没有特殊情况下推荐使用这种方式，以下是一个简单实例：
Currency currency = null;
//美国
currency = Currency.getInstance(Locale.US);
System.out.println("United States: " + currency.getSymbol());
//英国
currency = Currency.getInstance(Locale.UK);
System.out.println("United Kingdom: " + currency.getSymbol());
//法国
currency = Currency.getInstance(Locale.FRANCE);
System.out.println("France: " + currency.getSymbol());
//打印结果：
United States: USD
United Kingdom: GBP
France: EUR
