结论：

1、电商行业很挣钱，找互联网相关的工作。

2、电商行业技术要求很高、高可用、海量数据的存储。

  • 技术新
  • 技术范围广
  • 分布式
  • 高并发、集群、负载均衡、高可用
  • 海量数据
  • 业务复杂
  • 系统安全

宜立方商城介绍

宜立方B2C

管理员、运营可以在平台后台管理系统中管理商品、订单、会员等。

客服可以在后台管理系统中处理用户的询问以及投诉。

电商模式：

宜立方商城架构

后台管理系统：管理商品、订单、类目、商品规格属性、用户管理以及内容发布等功能。

前台系统：用户可以在前台系统中进行注册、登录、浏览商品、首页、下单等操作。

会员系统：用户可以在该系统中查询已下的订单、收藏的商品、我的优惠券、团购等信息。

订单系统：提供下单、查询订单、修改订单状态、定时处理订单。

搜索系统：提供商品的搜索功能。

单点登录系统：为多个系统之间提供用户登录凭证以及查询登录用户的信息。


系统架构

需要按照功能点把系统拆分，拆分成独立的功能。单独为某一个节点添加服务器。需要系统之间配合才能完成整个业务逻辑。叫做分布式。

分布式架构：多个子系统相互协作才能完成业务流程。系统之间需要进行通信。

集群：同一个工程部署到多台服务器上。

分布式架构：

把系统按照模块拆分成多个子系统。

优点：

1、把模块拆分，使用接口通信，降低模块之间的耦合度。

2、把项目拆分成若干个子项目，不同的团队负责不同的子项目。

3、增加功能时只需要再增加一个子项目，调用其他系统的接口就可以。

4、可以灵活的进行分布式部署。

缺点：

idjson

由于是单表查询可以使用逆向工程生成的代码。

id

TbItem

id

mapper

原因

此异常的原因是由于mappermappermavensrc/main/javamappertarget

解决方法

在e3-manager-daopom

<!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 -->

<build>

<resources>

src/main/java</directory>

xml</include>

</build>
