电商项目开发之开发环境搭建(一)
开发一个电商网站的所有模块
框架搭建、用户管理、商品分类、商品、订单、收货地址、购物车等
Spring框架
Spring是分层的JavaSE/EE full-stack(一站式) 轻量级开源框架
-
分层: SUN提供的EE的三层结构:控制层、业务层、数据访问层(持久层)
2.struts:web层 - Hibernate:数据访问层
- Mybatis:数据访问层
框架展示
搭建SSM框架-拷贝jar包
拷贝jar包:spring和springmvc的
Spring+SpringMVC的包:
AOP开发框架:Aspect
Spring依赖的jar包:
连接mysql数据:
连接池jar:
Springmvc的文件上传依赖Apache的fileupload组件:
Json数据:
jstl标准标签库:
Mybatis框架相关的jar包:
Mybatis的jar包:
Mybatis的依赖包:
Mybatis整合spring框架的jar包:
Mybatis下载地址:https://github.com/mybatis/mybatis-3/releases

搭建SSM框架-配置文件
2、配置文件
Spring的配置文件src下面创建:applicationContext.xml
完整的约束
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
http://www.springframework.org/schema/context

2、配置文件—Spring的配置文件applicationContext.xml
<!-- 配置扫描@Service @@Repository注解 -->
<context:component-scan base-package=“com.zq.service" />
<!--读取jdbc.properties -->
<context:property-placeholder location="classpath:jdbc.properties" />
<!-- 打开aspectj的注解开发方式 -->
<aop:aspectj-autoproxy />
<!-- 配置数据库连接 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${driverClass}"></property>
<property name="jdbcUrl" value="${jdbcUrl}"></property>
<property name="user" value="${user}"></property>
<property name="password" value="${password}"></property>
</bean>
<!-- 配置事务管理器 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 注册一下事务管理器的驱动 -->
<tx:annotation-driven transaction-manager="transactionManager" />
数据库连接信息src下面创建:jdbc.properties
driverClass=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://localhost:3306/shop
user=root
password=root
springMVC配置文件src下面创建:springmvc-config.xml(约束同spring配置文件的约束)
<!-- 配置扫描器 -->
<context:component-scan base-package="com.zq.controller" />
<!-- 注解驱动 -->
<mvc:annotation-driven />
<!--配置静态资源的访问映射,此配置中的文件,将不被前端控制器拦截 -->
<mvc:resources location="/js/" mapping="/js/**" />
<mvc:resources location="/css/" mapping="/css/**" />
<mvc:resources location="/images/" mapping="/images/**" />
<!-- 配置视图解释器ViewResolver -->
<bean id="jspViewResolver“ class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- 配置拦截器,先不加 -->
<!-- <mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**" />
<bean class="com.zq.interceptor.LoginInterceptor" />
</mvc:interceptor>
</mvc:interceptors> -->
2、配置文件—web.xml
<!-- 配置加载Spring文件的监听器-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<!-- 防止中文乱码,过滤器 -->
<filter>
<filter-name>encodingFilter</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>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
2、配置文件—web.xml
<servlet>
<!-- 前端控制器 -->
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 初始化加载配置文件 可以不配,不配时,默认加载的springmvc的配置文件,去WEB-INF下面找:servlet的名称-servlet.xml-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc-config.xml</param-value>
</init-param>
<!-- 表示容器一启动就加载servlet -->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
<!-- /拦截所有的请求,*.do拦截访问请求地址后缀是.do的 -->
</servlet-mapping>
