spring+mybatis+springmvc项目配置

项目下web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<!-- post请求 乱码过滤器 -->

<filter-name>encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>

<param-value>utf-8</param-value>
</init-param>

</filter-mapping>
<filter-mapping>

<!-- spring监听器 -->

<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>

<!-- 后台（卖家） -->

<servlet-name>back</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>

</web-app>

[b]tomcat/config/server.xml能解决get请求乱码，修改[/b]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"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<import resource="config/*.xml" />

</beans>

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"/>

<!-- 注解方式的-依赖注入 -->
<context:annotation-config/>

config/transaction.xml

<property name="dataSource" ref="dataSource"></property>
</bean>

<!-- 开启事务注解 -->
<tx:annotation-driven transaction-manager="transactionManager"/>

config/jdbc.xml

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

<property name="user" value="${user}" />

</bean>

config/property.xml

properties/jdbc.properties
driverClass=com.mysql.jdbc.Driver

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

Controller层对象交给springmvc处理
springmvc-back.xml 后台（卖家）管理系统
