</context-param> 

这个文件就是用来完成spring和mybatis的整合的。这里面也没多少行配置，主要的就是自动扫描，自动注入，配置数据库。注释也很详细，大家看看就明白了。

四、SpringMVC 框架配置

这块配置里面的注释也很详细，在此就不说了，主要是自动扫描控制器，视图模式，注解的启动这三个。

mvc-config.xml

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

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns:p="http://www.springframework.org/schema/p"

    xmlns:tx="http://www.springframework.org/schema/tx"

    xmlns:context="http://www.springframework.org/schema/context"

    xmlns:aop="http://www.springframework.org/schema/aop"

    xmlns:mvc="http://www.springframework.org/schema/mvc"

    xsi:schemaLocation="http://www.springframework.org/schema/beans

    http://www.springframework.org/schema/beans/spring-beans-3.1.xsd

    http://www.springframework.org/schema/mvc

    http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd

    http://www.springframework.org/schema/context

    http://www.springframework.org/schema/context/spring-context-3.1.xsd

    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd

    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd">

    <!-- 打开使用注解自动检测功能自动注册Bean，只扫描@Controller -->

    <context:component-scan base-package="com.demo"  use-default-filters="false">

        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />

    </context:component-scan>  

    <!-- 文件上传表单的视图解析器 -->

    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

        <property name="defaultEncoding" value="utf-8"></property>

        <property name="maxUploadSize" value="2097152"></property><!--限制文件上传2M内  -->

        <property name="maxInMemorySize" value="40960"></property>

    </bean>  

    <!-- 默认的注解映射的支持 - 增加String类型中文解析 -->

    <mvc:annotation-driven>

        <mvc:message-converters>

            <bean class="org.springframework.http.converter.StringHttpMessageConverter">

                <constructor-arg value="UTF-8" />

            </bean>

        </mvc:message-converters>

    </mvc:annotation-driven>

    <!-- 使用自定义Spring拦截器 -->

    <mvc:interceptors>

      <mvc:interceptor>

            <mvc:mapping path="/**" />

            <bean class="com.demo.common.core.SpringMVCInterceptor"></bean>

        </mvc:interceptor>

    </mvc:interceptors>    

    <!-- 视图配置 -->

    <!-- 对转向页面的路径解析,指定输出视图的前后缀，controller返回的视图直接加上此前后缀 -->

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"

        p:prefix="/project/" p:suffix=".jsp" />

</beans>

这部分内容也可以参考上一篇博文：《经久不衰的Spring框架：SpringMVC 统括》

五、部署与测试

到此，已经完成了SSM三大框架的整合了，接下来测试一下，如果成功了，那么恭喜你，如果失败了，继续调试吧，作为程序员就是不停的与BUG做斗争！
