第一篇：项目介绍&框架搭建

前言：
本文是一篇实战视频的笔记和总结。

1.电商的基本介绍

电商是什么？电子商务，就是网上交易所。比如淘宝，京东，阿里巴巴，1号店等等

1.1.电商行业的特点

技术新：和传统项目（比如XXX管理系统）相比，用到的技术比较新
技术范围广：不限于框架的整合，比如我们自己创建一个小项目的话，SSM或者SSH就可以解决我们的开发问题，但是由于电商涉及的数据量，访问量是巨大的，要整合其他很多技术
分布式
高并发（同时访问量大），集群，负载均衡，高并用
海量数据（涉及到的数据非常多，用大数据技术处理）
业务复杂
系统安全

电商的模式

B2B:商家到商家。阿里巴巴
B2C:商家到用户。京东
C2C:用户到用户。淘宝
B2B2C：商家到商家到用户。天猫
O2O：线上到线下。百度外卖，美团，饿了么

2.架构

2.1功能列表

2.2系统架构

传统架构：

1000并发：

image.png

当我们的访问达到10000的时候就需要20台服务器做tomcat集群。当tomcat集群中节点数量增加，服务能力先增加然后下降；这是因为资源都消耗在Tomcat之间的广播交流中。所以集群中节点数量不能太多，一般也就5个左右！！
解决方案：

分布式架构：多个子系统相互协作才能完成的业务流程。系统之间需要通信（webservice）
集群：同一个工程部署到多台服务器中。

分布式架构的优点和缺点：
优点：
1.把模块拆分，利用接口通信，降低了模块之间的耦合度
2.把项目拆分若干个子项目，方便团队协作
3.可以灵活的进行分布式部署
缺点：
1.系统职期间交互需要使用远程通信，增加接口开发量
2.一些通用的业务逻辑无法公用

2.3解决通用的业务逻辑无法公用的方案

image.png

系统的架构如下：

image.png

服务层和表现层之间用中间件Dubbo，加快交互的速度。服务处和数据层之间用redis缓存技术。持久层是Mysql的集群，由MyCat来建立一个逻辑上的数据库。Solr服务处理检索任务。消息队列则是处理每个模块的消息

3.系统的基本搭建

本项目的用的ide是idea，所以配置是按照是idea来的。项目配置利用的是Maven来管理，没有学习的朋友可以先去学习下Maven的基本应用

下面开始项目的搭建
开发ide:idea;
Maven:3.3.9

1.目录

image.png

简单介绍一下目录结构：
common-parent：为所有项目的父项目，主要用来管理所有项目使用的jar包及其版本。（所有的项目都应该继承父工程）
common-utils：为公共的工具类项目，继承父项目，它会被打成jar包供其它项目使用。
taotao-manager：为我们自己的项目，继承与我们的父项目，聚合工程。
taotao-manager-pojo为我们自己项目的一个子模块，依赖与taotao-manager,打成jar包
taotao-manager-dao为我们自己项目的一个子模块，依赖与taotao-manager-pojo,打成jar包
taotao-manager-service为我们自己项目的一个子模块，依赖与taotao-manager-dao,打成war包
taotao-manager-web为我们自己项目的一个子模块，依赖与taotao-manager-service,打成war包

2.创建父工程（common-parent）

1.创建新项目

image.png

来到创建目录，选择Empty project，next

image.png
来到New Project页面，填写project name，选择Project location，点Finish

image.png

等待IDEA加载完成，进行下一步
选择File–>New–>Module,进入New Module页面：

image.png
在New Module页面，按如下步骤操作：

image.png
填写组织名称和项目名称，以及版本号

image.png
配置本地maven目录及maven仓库配置文件

createParent8
创建父工程最后一步，给Module取名，及选择工作目录，选择完成

createParent9

等待生成pom文件，注意修改打包方式为pom，修改pom文件如下：


<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3.创建公共工具类

继承父项目

然后添加ArtifactId

修改pom

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

        </pluginManagement>
    </build>
</project>

4.创建业务编辑包

创建开发项目taotao-manager，其创建步骤同上，同样是继承common-parent,同样修改其pom文件，详细如下：

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

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>common-parent</artifactId>
        <groupId>com.lan</groupId>
        <version>1.0-SNAPSHOT</version>
        <relativePath>../common-parent/pom.xml</relativePath>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>taotao-manager</artifactId>
    <packaging>pom</packaging>

    <name>taotao-manager</name>
    <url>http://maven.apache.org</url>
    <modules>
        <module>../taotao-manager-pojo</module>
        <module>../taotao-manager-dao</module>
        <module>../taotao-manager-interface</module>
        <module>../taotao-manager-service</module>
        <module>../taotao-manager-web</module>
    </modules>

    <properties>

5.开发子模块

创建taotao-manager-pojo，dao,interface,service，web等子模块，详细如下：

image.png

与创建common-utils时不同，是将其子模块添加到taotao-manager目录下的：

image.png

创建taotao-manager下其它子模块:
另外的模块创建方式和上面所述的创建方式相同，只有web模块需要选择
