项目下web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"><display-name></display-name> <welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list><!-- post请求 乱码过滤器 --><filter><filter-name>encoding</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>encoding</filter-name><url-pattern>*.shtml</url-pattern></filter-mapping><filter-mapping><filter-name>encoding</filter-name><url-pattern>*.do</url-pattern></filter-mapping><!-- spring监听器 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:application-context.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- springmvc控制请求流转，有前台系统和后台系统之分 --><!-- 前台(买家) --><servlet><servlet-name>front</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc-front.xml</param-value></init-param></servlet><servlet-mapping><servlet-name>front</servlet-name><url-pattern>*.shtml</url-pattern></servlet-mapping><!-- 后台（卖家） --><servlet><servlet-name>back</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc-back.xml</param-value></init-param></servlet><servlet-mapping><servlet-name>back</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping></web-app>

tomcat/config/server.xml能解决get请求乱码，修改tomcat7下server.xml的第71行

    <Connector port="8080" protocol="HTTP/1.1"connectionTimeout="20000"redirectPort="8443" URIEncoding="UTF-8"/>

application-context.xml管理config文件夹下的配置文件

<?xml version="1.0" encoding="UTF-8"?>

config文件夹下文件的约束要与application-context.xml一致

config/annotation.xml

<!-- spring注解驱动扫包+依赖注入@Resource，不扫controller注解 -->
<context:component-scan base-package="cn.itcast"><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan><!-- 注解方式的-依赖注入 -->
<context:annotation-config/>

config/transaction.xml

<!-- spring事务 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"></property>
</bean><!-- 开启事务注解 -->
<tx:annotation-driven transaction-manager="transactionManager"/>

config/jdbc.xml

<!-- c3p0-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="driverClass" value="${driverClass}"/><property name="jdbcUrl" value="${jdbcUrl}"></property><property name="user" value="${user}" /><property name="password" value="${password}"/>
</bean>

config/property.xml

<!-- 读取jdbc配置 -->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><list><!-- jdbc配置 --><value>classpath:properties/jdbc.properties</value><!-- memcached配置 --></list></property>
</bean>

config/mybatis.xml

</bean><!-- mapper代理 管理dao-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="cn.itcast.core.dao"/>
</bean>

properties/jdbc.properties

driverClass=com.mysql.jdbc.Driver

jdbcUrl=jdbc:mysql://localhost:3306/babasport03?characterEncoding=UTF-8

user=root

password=root

Controller层对象交给springmvc处理

springmvc-back.xml 后台（卖家）管理系统
