首先在web.xml中配置Spring MVC的前端控制器，以及spring对于ORM/DAO的支持

<?xml version="1.0" encoding="UTF-8"?>  
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app\_3\_0.xsd" id="WebApp\_ID" version="3.0">  
  <display-name>springmvcch09</display-name>  
    
  <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>  
    
    
  <context-param>  
  <param-name>contextConfigLocation</param-name>  
  <param-value>classpath:bean.xml</param-value>  
  </context-param>  
  <listener>  
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
  </listener>  
    
    
  <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>  
  <init-param>  
  <param-name>forceRequestEncoding</param-name>  
  <param-value>true</param-value>  
  </init-param>  
  <init-param>  
  <param-name>forceResponseEncoding</param-name>  
  <param-value>true</param-value>  
  </init-param>  
  </filter>  
  <filter-mapping>  
  <filter-name>characterEncodingFilter</filter-name>  
  <url-pattern>\*</url-pattern>  
  </filter-mapping>  
  <welcome-file-list>  
    <welcome-file>/WEB-INF/jsp/index.jsp</welcome-file>  
  </welcome-file-list>  
</web-app>

注意：如果在前端控制器不配置

<init-param>  
      <param-name>contextConfigLocation</param-name>  
      <param-value>classpath:springmvc.xml</param-value>  
    </init-param>

（这里param-value的名字xxx.xml可以随便取）的时候，需要在WEB-INF中添加spring MVC的配置文件，并且名字必须为springMVC-servlet

在WEB-INF中配置springMVC-servlet，具体如下：

<?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"  
xmlns:aop="http://www.springframework.org/schema/aop"  
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd  
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd  
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd  
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd">  
  
  
<context:component-scan base-package="com.zx.controller"></context:component-scan>  
  
  
<mvc:default-servlet-handler/>  
  
  
  
<mvc:annotation-driven/>  
  
  
<mvc:resources location="/" mapping="\*.png"/>  
<mvc:resources location="/" mapping="\*.jpg"/>  
<mvc:resources location="/" mapping="\*.css"/>  
<mvc:resources location="/" mapping="\*.js"/>  
<mvc:resources location="/" mapping="\*.ico"/>  
<mvc:resources location="/" mapping="\*.gif"/>  
  
  
  
  
  
  
  
  
  
<bean id="resourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
  
<property name="prefix" value="/WEB-INF/jsp/"></property>  
  
<property name="suffix" value=".jsp"></property>  
</bean>  
  
</beans>

在src目录底下配置bean.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:aop="http://www.springframework.org/schema/aop"  
xmlns:context="http://www.springframework.org/schema/context"  
xmlns:tx="http://www.springframework.org/schema/tx"  
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd  
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd  
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd  
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">  
  
  
  
<context:annotation-config></context:annotation-config>  
  
  
<context:component-scan base-package="com.zx.service.impl"></context:component-scan>  
<context:component-scan base-package="com.zx.dao.impl"></context:component-scan>  
  
  
  
<context:property-placeholder location="classpath:jdbc.properties"/>  
  
  
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">  
<property name="driverClassName" value="$\{driver\}"></property>  
<property name="url" value="$\{url\}"></property>  
<property name="username" value="$\{usernamex\}"></property>  
<property name="password" value="$\{passwordx\}"></property>  
</bean>  
  
  
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
<property name="dataSource" ref="dataSource"></property>  
</bean>  
  
  
<tx:annotation-driven transaction-manager="transactionManager"/>  
  
  
  
  
  
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
<property name="dataSource" ref="dataSource"></property>  
  
<property name="typeAliasesPackage" value="com.zx.enity"></property>  
    
        <property name="mapperLocations" value="classpath:com/zx/dao/\*.xml"></property>   
</bean>  
  
  
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">  
<property name="basePackage" value="com.zx.dao"></property>  
</bean>  
</beans>

相应的在src目录地下配置对应的数据库的配置文件信息jdbc.properties

driver=com.mysql.jdbc.Driver  
url=jdbc:mysql://localhost:3306/test  
usernamex=root  
passwordx=root
