要讲的内容目录,我做的是简化版笔记。
新手:前提是你先的看一遍教程,后跟着本教程动手。
老手:直接跟着本教程动手。
背景说一堆,说明下面几点,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。
电商行业技术特点:
技术新、技术范围广、分布式、高并发、集群、负载均衡、高可用、冗余、海量数据、业务复杂、系统安全
视频中教了很多没用的,上面的是重点,且因为有技术特点,程序员们才有事干,有饭可吃。
要做的淘淘网上商城 =》 是一个综合性的B2C平台,类似京东商城、天猫商城。

淘淘商城系统架构
工程搭建
Taotao-parent:父工程,打包方式pom,管理jar包的版本号。
| 项目中所有工程都应该继承父工程。
|--Taotao-common:通用的工具类通用的pojo工程。打包方式jar
|--Taotao-manager:服务层工程。聚合工程。Pom工程
|--taotao-manager-dao:打包方式jar
|--taotao-manager-pojo:打包方式jar
|--taotao-manager-interface:打包方式jar
|--taotao-manager-service:打包方式:war
|--taotao-manager-web:表现层工程。打包方式war
开发环境:eclipsemars2
Maven:3.3.9
本地仓库:默认位置在~/.m2/repository
Eclipse需要配置maven3.39目录,及setting.xml文件配置指定repository目录。

Project Facets >DynamicWeb Module 3.0 à取消勾选,应用 à再勾选,下角有配置。地址:src/main/webapp
POM文件。<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"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.taotao</groupId> <artifactId>taotao-manager</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <artifactId>taotao-manager-service</artifactId> <packaging>war</packaging> <dependencies> <dependency> <groupId>com.taotao</groupId> <artifactId>taotao-manager-dao</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <!-- spring的依赖 --> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jms</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> </dependency> </dependencies> </project> |
四、Taotao-manager-web new > maven project
表现层,打包方式war。还要配置置webapp>WEB-INF>web.xml
Project Facets >DynamicWeb Module 3.0 à取消勾选,应用 à再勾选,下角有配置。地址:src/main/webapp
POM文件。<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"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.taotao</groupId> <artifactId>taotao-parent</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <artifactId>taotao-manager-web</artifactId> <packaging>war</packaging> <dependencies> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jms</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> </dependency> <!-- JSP相关 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>${jstl.version}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <scope>provided</scope> </dependency> </dependencies> </project> |
上面搭建工程,接下来。
启动工程
taotao-manager,port:8080, taotao-manager-web,port:8081,
添加tomcat插件,在pom工程中,配置tomcat插件,启动的端口号,和工程名称。
在taotao-manager 和 taotao-manager-web 的pom文件中添加如下配置:
<!-- 配置tomcat插件 --> <build> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <configuration> <port>8080</port> <path>/</path> 用/的话,就不要在http://www.taobao.com上填项目名了 </configuration> </plugin> </plugins> </build> |
且在这两个WAR工程中,添加文件。webapp 》添加index.jsp > hello!
RunAS..>maven build >启动tomcat插件:clean tomcat7:run
启动taotao-manager-web项目,或,taotao-manager
先把taotao-parent、taotao-common安装到本地仓库。然后再启动。
这里可以注意下,taotao-manager是个聚合工程,有四个模块pojo,interface,service,dao
pojo,dao,interface 是jar,service是war。运行service即web工程,必须每次先安装另三个。
所以,直接配置和运行taotao-manager聚合工程,四个模块会自动聚合。
Svn的使用
服务端
使用VisualSVN,一般一个项目组只有一个svn,并不是每个开发者都需要安装服务端。新建的Repositories,项目有三个文件夹,branches,tags,trunk。
一般将工程放在主干trunk上。
客户端
客户端使用Eclipse的svn插件,在提供的Eclipse中已经安装好,直接使用即可。
上传注,可只上传四项目。taotao-parent,taotao-common,taotao-manager,taotao-manager-web
因为taotao-manager是聚合工程,moulder可以不要上传。
可以假删除,mous模块工程,左聚合工作中,Import…/Existing Mavenprojects
会自动添加进行。
