第一步：添加Jar包：


第二步：配置web.xml文件


<?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"

	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

  <context-param>
		 <param-name>webAppRootKey</param-name>
		  <param-value>
				 SSH1
		 </param-value>
</context-param>

<listener>
       <listener-class>
              org.springframework.web.context.ContextLoaderListener
       </listener-class>
</listener>

<context-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>
                 classpath:spring*.xml
          </param-value>
</context-param>

<listener>

		<param-value>classpath:log4j.properties</param-value>
</context-param>


<listener>
   <listener-class>
	   org.springframework.web.context.request.RequestContextListener
   </listener-class>
</listener>
<listener>
    <listener-class>
         org.springframework.web.util.IntrospectorCleanupListener
    </listener-class>
</listener>

<filter>
   <filter-name>openSessionInView</filter-name>
   <filter-class>           
          org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
   </filter-class>
</filter>
<filter-mapping>
     <filter-name>openSessionInView</filter-name>
     <url-pattern>*.do</url-pattern>
</filter-mapping> 

<servlet>
	    <servlet-name>SpringMVC</servlet-name>
	    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
	    <init-param>
	        <param-name>contextConfigLocation</param-name>
	        <param-value>classpath:spring*.xml</param-value>
	    </init-param>
	    <load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
	    <servlet-name>SpringMVC</servlet-name>

	</filter-mapping>
  
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

第三步：在根目录下添加两个文件：spring-common.xml   spring-mvc.xml


spring-common.xml

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

	   </property> 
   </bean>
    <!-- 第三步：配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">  
        <property name="sessionFactory" ref="sessionFactory"/>

    <!--第四步：为事务管理器，配置事务的传播特性 -->
 
     <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>

     </tx:advice>
        <!-- 强制使用CGLIB生成代理类 -->
       <!--<aop:aspectj-autoproxy proxy-target-class="true"/>-->

spring-mvc.xml

</beans>


第四步：根目录下添加log4j配置文件 log4j.properties  

第五步：测试！！！
