摘 要

通俗的讲直销银行就是将线下银行的各个业务转移到线上来开展，直销银行在我国起步较晚，现价段仍然处于初级阶段，由于传统银行给人们长期带来的固化方式，让直销银行目前很难被人接受，又加之银行推出的网上银行等类似软件和直销银行软件的功能重复，让人也很难区分其差别。但是，直销银行有着其自身的独特的优势，国家和银行等也在加大对其重视程度，尤其这次突发的疫情，相比传统银行更凸现了它的优势。利用直销银行系统，人们无需前往实体柜台就可以完成账户的开户，理财的购买等操作。这对于用户和银行是一种双赢的局面。

本课题设计的直销银行系统主要包含四个系统，分别是虚拟银行系统，直销银行核心系统，身份认证系统和后台管理系统。虚拟银行系统主要包含以下几个功能：登录、注册、开户、绑卡、充值、提现、理财产品展示、理财申购、理财赎回、交易记录查询和已购产品的展示等。互联网核心系统主要负责处理动账操作。身份认证系统主要负责用户注册时的实名认证。后台管理系统主要负责理财产品的添加，修改，删除等操作。JAVA目前依然是排名第一的后台开发语言，所以该系统的接口编写全部用JAVA语言编写，虚拟银行系统使用Spring框架，后管系统采用Struts2，前端使用Angular框架。

Abstract

Popular speak direct bank is the various business will be offline bank transfer to line up, direct bank in our country starts late, a market segment is still in its infancy, due to the traditional bank bring people long-term way of curing, make direct bank is now hard to accept, and combined with the bank of the bank on the net, such as the function of the software and direct bank repeat, let a person is difficult to distinguish the difference.
