一、商城项目概述
这是一个基于Dubbo分布式服务架构的B2C商城系统，对，就是网上随处可见的那种商城，可以在商城寻找心仪的商品，下订单，参加各种优惠活动。
。
客服可以在后台管理系统中处理用户的询问以及投诉。
分布式是吧，那你说一下啥叫分布式噻？
啊，分布式......
分布式：就是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，就叫做分布式。
有撒子好处喔？
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：
1、系统之间交互需要使用远程通信，接口开发增加工作量。
2、各个模块有一些通用的业务逻辑无法共用，增加了重复代码。
这不算缺点，反正我又不敲代码。你详细说说这个系统有哪些功能模块吧。
我还是上图给你看吧。
架构图：

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。
。
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。
唔，功能还挺全活，那你们的项目架构是咋样的呢？
我们这是基于SOA的架构...
啥叫SOA呢？我英文不好的。
SOA：Service Oriented Architecture面向服务的架构。也就是把工程拆分成服务层、表现层两个工程。服务层中包含业务逻辑，只需要对外提供服务即可。表现层只需要处理和页面的交互，业务逻辑都是调用服务层的服务来实现。
像我们这个商城的系统的系统架构就是：
image.png
后台工程的搭建结构：
yysc-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。
|--yysc-common：通用的工具类通用的pojo。打包方式jar
|--yysc-manager：服务层工程。聚合工程。Pom工程
|--yysc-manager-dao：打包方式jar
|--yysc-manager-pojo：打包方式jar
|--yysc-manager-interface：打包方式jar
|--yysc-manager-service：打包方式：war
|--yysc-manager-web：表现层工程。打包方式war
二、基本结构搭建
这个项目是用maven管理项目jar包的，所以主要是pom文件里的配置。
yysc-parent:定义整个项目需要用到的jar包和插件

三、框架整合
image.png至于springmvc的配置文件则放在web项目中
1.Dao层
mybatis整合spring，通过spring管理SqlSessionFactory、mapper代理对象。
application_mapper文件配置（manager-service项目中）
实例化数据库连接池
实例化SqlSessionFactory
产生Mappper接口的代理对象
<?xml version="1.0" encoding="UTF-8"?>
<beans
xsi:schemaLocation="
">
<!-- 实例化数据库连接池 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
<!-- 注入数据库连接信息 -->
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
<property name="url" value="jdbc:mysql://127.0.0.1:3306/yysc"></property>
<property name="username" value="root"></property>
<property name="password" value="root"></property>
</bean>
<!-- 实例化SqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 注入dataSource数据库连接池 -->
<property name="dataSource" ref="dataSource"></property>
<!-- 配置分页插件 -->
<property name="plugins">
<list>
<bean class="com.github.pagehelper.PageHelper">
<property name="properties">
<props>
<!-- 配置分页插件的方言 -->
<prop key="dialect">mysql</prop>
<!-- 分页的合理化参数 -->
<prop key="reasonable">true</prop>
</props>
</property>
</bean>
</list>
</property>
</bean>
<!--
产生Mappper接口的代理对象
MapperScannerConfigurer：扫描com.bjsxt.mapper接口中的接口文件和xml文件
然后产生接口的代理对象
规范：将mapper.java 和 mapper.xml放入统一包
mapper.java 和 mapper.xml 文件名字一样
代理对象的id：mapper接口的名字第一个字母小写
-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 注入Mapper接口所在的包 -->
<property name="basePackage" value="com.yzy.yysc.manager.mapper"></property>
<!-- 注入sqlSessionFactory -->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>
</beans>
2、Service层：
所有的service实现类都放到spring容器中管理。由spring创建数据库连接池，并有spring管理实务。
application_service文件配置（manager-service项目中）
将业务对象，那入spring容器:扫描接口实现类
声明事务管理器对象
声明事务切面
进行aop配置：面向切面编程
<?xml version="1.0" encoding="UTF-8"?>
<beans
xsi:schemaLocation="
">
<!-- 将业务对象，那入spring容器 -->
<context:component-scan base-package="com.yzy.yysc.manager.service.impl">
</context:component-scan>
<!-- 声明事务管理器对象 -->

<dubbo:service interface="com.yzy.yysc.manager.service.ItemCatService" ref="itemCatServiceImpl" timeout="300000"/>
</beans>
3、表现层：
Springmvc框架，由springmvc管理controller。
springmvc文件配置（manager-web项目中）
将控制层对象，那入spring容器:扫描controller包
springmvc的注解驱动
配置二进制流解析器：上传下载会用到
配置视图解析器：免去写前缀后缀的痛苦
配置资源映射
<?xml version="1.0" encoding="UTF-8"?>
<beans
xsi:schemaLocation="
">
<context:component-scan base-package="com.yzy.yysc.manager.controller"></context:component-scan>
<!--
springmvc的注解驱动
-->
<mvc:annotation-driven></mvc:annotation-driven>
<!-- 配置二进制流解析器
<bean id="multipartResolver"
<!– 设置允许上传的文件最大的尺寸 –>
<property name="maxUploadSize" value="10240000"></property>
<!– 设置文件上传过程中，中文的编码 –>
<property name="defaultEncoding" value="UTF-8"></property>
<!– 设置文件上传的保存目录 –>
<property name="uploadTempDir" value="/upload"></property>
</bean>-->
<mvc:resources location="/WEB-INF/js/" mapping="/js/**"/>
<mvc:resources location="/WEB-INF/css/" mapping="/css/**"/>
<mvc:resources location="/WEB-INF/images/" mapping="/images/**"/>
<mvc:resources location="/WEB-INF/zTree/" mapping="/zTree/**"/>
<mvc:resources location="/WEB-INF/layui/" mapping="/layui/**"/>
<mvc:resources location="/WEB-INF/jsp/" mapping="/jsp/**"/>
<!-- 配置视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 引用dubbo服务 -->
<dubbo:application name="yy-manager-web"/>
<dubbo:registry protocol="zookeeper"
address="192.168.245.130:2181,192.168.245.130:2182,192.168.245.130:2183" />
<dubbo:reference interface="com.yzy.yysc.manager.service.ItemService" id="itemService" />
<dubbo:reference interface="com.yzy.yysc.manager.service.MenusService" id="menusService" />
<dubbo:reference interface="com.yzy.yysc.manager.service.ItemCatService" id="itemCatService" />
</beans>
4.Service项目的web.xml配置
因为与前端交互的并不是service层，所以这里只要配置spring容器的初始化即可。
<?xml version="1.0" encoding="UTF-8"?>
<web-app
id="WebApp_ID" version="2.5">
<display-name>taotao-manager</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!-- 初始化spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:application_*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>
5.web项目的web.xml配置
中文乱码处理
配置springmvc的核心控制器
spring容器在service项目中加载过了，所以这里无需再加载了
<?xml version="1.0" encoding="UTF-8"?>
<web-app
id="WebApp_ID" version="2.5">
<display-name>yy-manager-web</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!-- post乱码过滤器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 前端控制器 -->
<servlet>
<servlet-name>yy-manager-web</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- contextConfigLocation不是必须的， 如果不配置contextConfigLocation， springmvc的配置文件默认在：WEB-INF/servlet的name+"-servlet.xml" -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>yy-manager-web</servlet-name>
<!-- 拦截所有请求jsp除外 -->
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
整合完毕，打包启动测试一下吧。
这里的测试是指manager项目和manager-web项目分别测试额，能跑起来就行了，而且先要把配置文件中关于dubbo服务的配置先注释掉，不然会报错额。
行，小伙子不错，回去等消息吧，如果公司需要临时工的话，我会优先考虑你的。祝你好运。see you la la。
