01_DERAM商城项目设计与工程搭建
1.商城项目分析与设计
- 附件：商城项目设计.pdf
2.技术选型和开发环境
2.1 技术选型
-
Spring、SpringMVC、Mybatis
-
JSP、JSTL、jQuery、EasyUI、KindEditor（富文本编辑器）
-
Redis（缓存服务器，单点登录，购物车）
-
Solr（搜索）
-
dubbo（分布式服务框架）HttpClient（HTTP 协议访问客户端）
-
ActiveMQ（消息队列）
-
Quartz（定时任务）
-
FastDFS（图片服务器）
-
FreeMarker（网页静态化）
-
Nginx（反向代理服务器）
-
MyCat（数据库中间件）
5.5 开发环境
-
IntelliJ IDEA 2019.2.2 x64
-
Maven 3.3.9
-
Tomcat 7.0.92（Maven Tomcat Plugin）
-
JDK 1.8
-
Mysql 5.7
-
Dubbo 2.5.3
-
Nginx 1.8.0
-
Redis 3.0.0
-
ActiveMQ 5.13.0
-
Win10 操作系统
-
GIT（版本管理）
3.工程搭建
3.1 使用Maven搭建工程
-
好处
- 管理jar包
- 管理工程之间的依赖关系
- 自动打包
- 统一版本控制
-
工程分析的结构(根据功能模块会搭建很多工程，先搭建后台管理工程)
-
Maven的常见打包方式
- jar：java工程
- war：web工程
- pom：聚合工程(可以包含子工程)
-
结构
- dream_parent：dream商城的父工程，pom，管理整个项目的统一的版本号，所有项目都继承它
- dream_common：通用的工具类的工程，通用的类型pojo,工具util，jar
- dream_manager：后台管理服务层工程。pom
- dream_manager_pojo：后台管理的pojo类型 jar
- dream_manager_dao：dao层，为service提供接口 jar
- dream_manager_interface：接口工程 jar
- dream_manager_service：提供服务的业务层工程 war(为了方便发布服务)
- dream_manager_web：后台管理的表现层，调用所有关于后台操作的业务层服务war
结构不要弄错！！！
- dream_parent：dream商城的父工程，pom，管理整个项目的统一的版本号，所有项目都继承它
-
3.2 工程搭建
-
dream_parent
-
新建一个空project,取名为dream
-
new->module->Maven
-
填写名称：dream_parent
-
next->finish
-
编辑pom.xml，更改打包方式为pom
-
添加jar包依赖和版本控制–pom.xml

打包安装一下：把当前的parent项目安装maven的本地仓库中，其他的项目就可以进行依赖了
-
-
dream_common
-
继承_parent，但是目录不在 _parent下
-
右键parent工程->new->module
-
maven->next
-
更改文件root
-
添加打包jar
-
添加依赖

-
3.3 启动工程
-
先启动manager
-
添加tomcat插件
-
配置maven启动
-
启动查看
-
-
启动web工程
-
添加tomcat，端口号设置为8080
<build> <plugins> <plugin> <groupId>org.apache.tomcat.mavengroupId> <artifactId>tomcat7-maven-pluginartifactId> <configuration> <port>8080port> <path>/path> configuration> plugin> plugins> build> -
配置maven启动
-
启动测试
-
3.4 项目目录
4.SSM整合
4.1 搭建商城项目的数据库环境
-
新建一个数据库dream
-
运行sql文件
- 右键数据库->运行sql文件->选择dream.sql
- 右键数据库->运行sql文件->选择dream.sql
4.2 使用MyBatis-逆向工程生成pojo和mapper文件，拷贝到pojo和dao下
-
在MyBatis的配置文件中，修改连接的数据库，生成的数据的包，和指定的数据表
-
SOA的架构是需要pojo在项目中进行传输，需要对象流，把对象进行序列化，所有的pojo都需要实现序列化接口
-
在MyBaits逆向工程生成时，指定需要实现序列化接口
<plugin type="org.mybatis.generator.plugins.SerializablePlugin" />
-
-
把pojo拷贝到_pojo下，把mapper拷贝到 _dao下
4.3 配置dao层和service层
-
在_service下新建java和resources
-
在resources下新建3个资源文件夹
-
mybatis
-
进行MyBatis的配置SqlMapConfig.xml
<configuration> configuration>
-
-
spring
-
