目录
1.购物车系统的架构
cart系统架构：
taotao-cart（pom聚合工程）
|--taotao-cart-interface（jar）
|--taotao-cart-Service（war）
Taotao-cart-web(war)
可以参考taotao-manager,taotao-manager-web创建
2.服务层工程搭建
服务层工程负责查询，修改，删除，更新（包括购物车存于cookie和数据库）

右键taotao-cart-service--》javaEE tools--》Generate...xxxxx，会自动帮我们生成web.xml
将taotao-sso-service的src/main/resources下的配置文件全部复制到taotao-cart-service的src/main/resources
删除与数据库相关的配置文件，因为购物车主要使用redis缓存，所以需要将redis的工具类拿过来
修改applicationContext-service.xml中spring注解包扫描与dubbo暴露服务的端口
在web.xml中配置spring的监听器
<!-- 初始化spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
