走进电商

电商行业分析

近年来，中国的电子商务快速发展，交易额连创新高，电子商务在各领域的应用不断拓展和深化、相关服务业蓬勃发展、支撑体系不断健全完善、创新的动力和能力不断增强。电子商务正在与实体经济深度融合，进入规模性发展阶段，对经济社会生活的影响不断增大，正成为我国经济发展的新引擎。

中国电子商务研究中心数据显示，截止到 2012 年底，中国电子商务市场交易规模达 7.85万亿人民币，同比增长 30.83%。其中，B2B 电子商务交易额达 6.25 万亿，同比增长 27%。而 2011 年全年，中国电子商务市场交易额达 6 万亿人民币，同比增长 33%，占 GDP 比重上升到 13%；2012 年，电子商务占 GDP 的比重已经高达 15%。

主要电商模式

B2B – 企业对企业

B2B （ Business to Business）是指进行电子商务交易的供需双方都是商家（或企业、公司），她（他）们使用了互联网的技术或各种商务网络平台，完成商务交易的过程。电子商务是现代 B2B marketing的一种具体主要的表现形式。
案例：阿里巴巴、慧聪网

C2C – 个人对个人

C2C即 Customer（Consumer） to Customer（Consumer），意思就是消费者个人间的电子商务行为。比如一个消费者有一台电脑，通过网络进行交易，把它出售给另外一个消费者，此种交易类型就称为C2C电子商务。
案例：淘宝、易趣、瓜子二手车

B2C – 企业对个人

B2C是Business-to-Customer的缩写，而其中文简称为“商对客”。“商对客”是电子商务的一种模式，也就是通常说的直接面向消费者销售产品和服务商业零售模式。这种形式的电子商务一般以网络零售业为主，主要借助于互联网开展在线销售活动。B2C即企业通过互联网为消费者提供一个新型的购物环境——网上商店，消费者通过网络在网上购物、网上支付等消费行为。
案例：唯品会、乐蜂网

C2B – 个人对企业

C2B（Consumer to Business，即消费者到企业），是互联网经济时代新的商业模式。这一模式改变了原有生产者（企业和机构）和消费者的关系，是一种消费者贡献价值（Create Value），企业和机构消费价值（Consume Value）。
C2B模式和我们熟知的供需模式（DSM, Demand Supply Model）恰恰相反，真正的C2B 应该先有消费者需求产生而后有企业生产，即先有消费者提出需求，后有生产企业按需求组织生产。通常情况为消费者根据自身需求定制产品和价格，或主动参与产品设计、生产和定价，产品、价格等彰显消费者的个性化需求，生产企业进行定制化生产。
案例：海尔商城、尚品宅配

O2O – 线上到线下

O2O即Online To Offline（在线离线/线上到线下），是指将线下的商务机会与互联网结合，让互联网成为线下交易的平台，这个概念最早来源于美国。O2O的概念非常广泛，既可涉及到线上，又可涉及到线下,可以通称为O2O。主流商业管理课程均对O2O这种新型的商业模式有所介绍及关注。
案例：美团、饿了吗

F2C – 工厂到个人

F2C指的是Factory to customer，即从厂商到消费者的电子商务模式。

B2B2C – 企业-企业-个人

B2B2C是一种电子商务类型的网络购物商业模式，B是BUSINESS的简称，C是CUSTOMER的简称，第一个B指的是商品或服务的供应商，第二个B指的是从事电子商务的企业，C则是表示消费者。
第一个BUSINESS，并不仅仅局限于品牌供应商、影视制作公司和图书出版商，任何的商品供应商或服务供应商都能可以成为第一个BUSINESS；第二B是B2B2C模式的电子商务企业，通过统一的经营管理对商品和服务、消费者终端同时进行整合，是广大供应商和消费者之间的桥梁，为供应商和消费者提供优质的服务，是互联网电子商务服务供应商。C表示消费者，在第二个B构建的统一电子商务平台购物的消费者；
B2B2C的来源于目前的B2B、B2C模式的演变和完善，把B2C和C2C完美地结合起来，通过B2B2C模式的电子商务企业构建自己的物流供应链系统，提供统一的服务。
案例：京东商城、天猫商城

品优购 – 需求分析与系统设计

品优购介绍

品优购网上商城是一个综合性的 B2B2C 平台，类似京东商城、天猫商城。网站采用商家入驻的模式，商家入驻平台提交申请，有平台进行资质审核，审核通过后，商家拥有独立的管理后台录入商品信息。商品经过平台审核后即可发布。

品优购网上商城主要分为网站前台、运营商后台、商家管理后台三个子系统

网站前台

主要包括网站首页、商家首页、商品详细页、、搜索页、会员中心、订单与支付相关页面、秒杀频道等。

运营商后台

是运营商的运营人员的管理后台。主要包括商家审核、品牌管理、规格管理、模板管理、商品分类管理、商品审核、广告类型管理、广告管理、订单查询、商家结算等。

商家管理后台

入驻的商家进行管理的后台，主要功能是对商品的管理以及订单查询统计、资金结算等功能。

系统架构

什么是SOA架构

SOA是Service-Oriented Architecture的首字母简称，它是一种支持面向服务的架构样式。从服务、基于服务开发和服务的结果来看，面向服务是一种思考方式。其实SOA架构更多应用于互联网项目开发。
为什么互联网项目会采用SOA架构呢？随着互联网的发展，网站应用的规模不断扩大，常规的垂直应用架构已无法应对，分布式服务架构以及流动计算架构势在必行，迫切需一个治理系统确保架构有条不紊的演进。

框架组合

品优购采用当前流行的前后端编程架构
后端框架采用Spring + SpringMVC + Mybatis + Dubbox
前端采用AngularJS + Bootstrap

Dubbox框架

Dubbox简介

Dubbox 是一个分布式服务框架，其前身是阿里巴巴开源项目Dubbo ，被国内电商及互联网项目中使用，后期阿里巴巴停止了该项目的维护，当当网便在Dubbo基础上进行优化，并继续维护，为了与原有的Dubbo区分，故将其命名为Dubbox。
Dubbox 致力于提供高性能和透明化的RPC远程服务调用方案，以及SOA服务治理方案。简单的说，dubbox就是个服务框架，如果没有分布式的需求，其实是不需要用的，只有在分布式的时候，才有dubbox这样的分布式服务框架的需求，并且本质上是个服务调用的东东，说白了就是个远程服务调用的分布式框架。
1. 节点角色说明：
  1. Provider: 暴露服务的服务提供方。
  2. Consumer: 调用远程服务的服务消费方。
  3. Registry: 服务注册与发现的注册中心。
  4. Monitor: 统计服务的调用次调和调用时间的监控中心。
  5. Container: 服务运行容器。
2. 调用关系说明：
  1. 服务容器负责启动，加载，运行服务提供者。
  2. 服务提供者在启动时，向注册中心注册自己提供的服务。
  3. 服务消费者在启动时，向注册中心订阅自己所需的服务。
  4. 注册中心返回服务提供者地址列表给消费者，如果有变更，注册中心将基于长连接推送变更数据给消费者。
  5. 服务消费者，从提供者地址列表中，基于软负载均衡算法，选一台提供者进行调用，如果调用失败，再选另一台调用。
  6. 服务消费者和提供者，在内存中累计调用次数和调用时间，定时每分钟发送一次统计数据到监控中心。

注册中心Zookeeper

Zookeeper介绍

官方推荐使用 zookeeper 注册中心。注册中心负责服务地址的注册与查找，相当于目录服务，服务提供者和消费者只在启动时与注册中心交互，注册中心不转发请求，压力较小。
Zookeeper 是 Apacahe Hadoop 的子项目，是一个树型的目录服务，支持变更推送，适合作为Dubbox 服务的注册中心，工业强度较高，可用于生产环境。

Zookeeper在Linux系统的安装

安装步骤：
1. 第一步：安装jdk
2. 第二步：把Zookeeper的压缩包上传到linux系统，或直接下载
```
$ wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/current/zookeeper-3.4.12.tar.gz
```
3. 第三步：解压缩压缩包
```
$ tar -zxvf zookeeper-3.4.12.tar.gz
```
4. 第四步：进入Zookeeper-3.4.12目录，创建data文件夹
```
$ cd zookeeper-3.4.12/
$ mkdir data
```
5. 第五步：进入conf目录，把zoo_sample.cfg改名为zoo.cfg
```
$ cd conf/
$ mv zoo_sample.cfg zoo.cfg
```
6. 第六步：打开zoo.cfg，修改data属性：dataDir=/root/zookeeper-3.4.12/data
```
vi zoo.cfg
```

Zookeeper服务启动

进入bin目录，启动服务
```
$ ./zkServer.sh start
```
关闭服务
```
$ ./zkServer.sh stop
```
查看状态
```
$ ./zkServer.sh status
```

Dubbox本地 JAR包部署与安装（了解）

Dubbox的jar包并没有部署到Maven的中央仓库中，大家在Maven的中央仓库中可以查找到Dubbo的最终版本是2.5.3 , 阿里巴巴解散了Dubbo团队后由当当网继续维护此项目，并改名为 Dubbox ,坐标不变，版本变更了，但是并没有提交到中央仓库。
我们现在需要手动将Dubbox的jar包安装到我的本地仓库中。

先将dubbo-2.8.4.jar包放到/data/下, 然后输入命令

$ mvn install:install-file -Dfile=/data/dubbo-2.8.4.jar -DgroupId=com.alibaba -DartifactId=dubbo -Dversion=2.8.4 -Dpackaging=jar

入门小Demo

服务提供者开发

创建Maven工程（war）dubboxdemo-service，在pom.xml中引入依赖

<?xml version="1.0" encoding="UTF-8"?>

创建包com.huangwangxin.dubbodemo.service，用于存放业务接口

创建接口UserService文件

package com.huangwangxin.dubbodemo.service;/*** 业务接口** @author wangxinhuang* @date 2018/6/20*/
public interface UserService {public String getName();
}

创建实现类

创建包com.huangwangxin.dubbodemo.service，用于存放业务实现类

创建业务实现类UserServiceImpl文件

package com.huangwangxin.dubbodemo.service.impl;import com.alibaba.dubbo.config.annotation.Service;
import com.huangwangxin.dubbodemo.service.UserService;/*** 业务实现类** @author wangxinhuang* @date 2018/6/20*/
@Service
public class UserServiceImpl implements UserService {@Overridepublic String getName() {return "Dubbo Demo";}
}

注意，此处Service注解使用的是com.alibaba.dubbo包

测试运行
1. 新建maven命令
2. 运行
3. 访问http://localhost:8082/user/showName.do

管理中心的部署

在开发时，需要知道注册中心都注册了哪些服务，以便我们开发和测试，我们可以通过部署一个管理中心来实现。

管理端安装

下载并解压

$ wget https://codeload.github.com/dangdangdotcom/dubbox/zip/dubbox-2.8.4
$ unzip dubbox-2.8.4

进入dubbox-admin，输入maven命令

$ cd dubbox-dubbox-2.8.4/dubbo-admin/
$ mvn package -Dmaven.skip.test=true

编译成功

进入target文件夹，将dubbo-admin-2.8.4.war放到tomcat的webapps下

$ cp dubbo-admin-2.8.4.war /usr/local/tomcat/webapps/dubbo-admin.war
# 启动tomcat
$ /usr/local/tomcat/bin/startup.sh

管理端使用

打开浏览器，输入http://192.168.31.144:8081/dubbo-admin/，登录用户名和密码为root，进入首页

实体类与数据访问层模块

生成代码

利用逆向工程实现实体类和数据访问层代码自动生成

拷贝代码

将com.huangwangxin.pojo拷贝到pojo工程
将com.huangwangxin.mapper包和resource的com.huangwangxin.mapper文件夹下拷贝dao工程

修改实体类代码

修改每个实体类，实现Serializable接口
```
public class TbUser implements Serializable
```

品牌列表-后端代码

需求分析

完成品牌管理的后端代码，在浏览器可查询品牌的数据（json格式）

数据库表

tb_brand 品牌表

字段	类型	长度	含义
Id	Bigint		主键
Name	Varchar	255	品牌名称
First_char	Varchar	1	品牌首字母

后端代码

服务层接口

在pinyougou-sellergoods-interface工程创建BrandService接口

package com.huangwangxin.service;import com.huangwangxin.pojo.TbBrand;import java.util.List;/*** 品牌服务层接口** @author wangxinhuang* @date 2018/6/27*/
public interface BrandService {/*** 返回全部列表* */public List<TbBrand> findAll();
}

服务实现类

在pinyougou-sellergoods-service工程创建BrandServiceImpl

package com.huangwangxin.sellergoods.service.impl;import com.alibaba.dubbo.config.annotation.Service;
import com.huangwangxin.mapper.TbBrandMapper;
import com.huangwangxin.pojo.TbBrand;
import com.huangwangxin.service.BrandService;
import org.springframework.beans.factory.annotation.Autowired;import java.util.List;/*** 品牌服务实现** @author wangxinhuang* @date 2018/6/27*/
@Service
public class BrandServiceImpl implements BrandService {@Autowiredprivate TbBrandMapper brandMapper;@Overridepublic List<TbBrand> findAll() {return brandMapper.selectByExample(null);}
}

控制层

在pinyougou-manager-web创建BrandController类

package com.huangwangxin.manager.controller;import com.alibaba.dubbo.config.annotation.Reference;
import com.huangwangxin.pojo.TbBrand;
import com.huangwangxin.service.BrandService;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.util.List;/*** 品牌** @author wangxinhuang* @date 2018/6/27*/
@RestController
@RequestMapping("/brand")
public class BrandController {@Referenceprivate BrandService brandService;/*** 返回品牌全部列表 all list.** @return the list*/@RequestMapping("/findAll")public List<TbBrand> findAll() {return brandService.findAll();}}

测试

启动pinyougou-sellergoods-service
启动pinyougou-manager-web
访问http://localhost:9101/brand/findAll.do

原因：创建文件resources/spring/applicationContext-service.xml的时候，文件名写成applicatinContext，缺少一个字母o，在web.xml中导入出现问题。
