本文是自己在学习SpringMVC做一个简单记录，方便以后自己忘记回来查询。

第一步：配置DispatcherServlet以及字符编码处理

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

<web-app version="2.5" 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_2_5.xsd">


<servlet>

<servlet-name>springMVC</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>



<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>springMVC</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>



<filter>

<filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

</web-app>

第二步：新建SpringMVC控制器，注明：在新建SpringMVC控制器的文件名必须与web.xml中DispatcherServlet中的servletName一致

SpringMVC-servlet中的配置文件信息如下：

<?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:context="http://www.springframework.org/schema/context"

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

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">





<context:component-scan base-package="org.ksea.controller"/>

<mvc:annotation-driven/>



<mvc:resources location="/resources/" mapping="/resources/**"/>



<bean id="exceptionResolver"

class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">

<property name="exceptionMappings">

<props>



<prop key="org.ksea.exception.UserExcetion" >user/error</prop>

</props>

</property>

</bean>



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



<property name="maxUploadSize" value="5000000"></property>

</bean>



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



<property name="prefix" value="/WEB-INF/pages/"/>



<property name="suffix" value=".jsp"/>

</bean>

</beans>

-----------------------以上为SpringMVC框架的一个简单配置---------------------------------------------
