1.首先jar包需要提前准备好：

2.其次配置

首先配置struts的拦截器和spring的监听器

<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> 
      
       
      <filter>
      	<filter-name>struts2</filter-name>
      	<filter-class>
      		org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
      	</filter-class>
      </filter>
      <filter-mapping>
      	<filter-name>struts2</filter-name>
      	<url-pattern>*.action</url-pattern>
      </filter-mapping>

3.配置spring的xml

struts.xml配置：

<struts>
    	          <constant name="struts.multipart.saveDir" value="/tmp"></constant>
    	          <constant name="struts.devMode" value="true" />
    	          <constant name="struts.action.extension" value="action"></constant>
       	          <constant name="struts.i18n.encoding" value="utf8"></constant> 
       	          <constant name="struts.objectFactory" value="spring" />
       	          
       	          
       	     <package name="user" extends="struts-default" namespace="/user">
    
    		  <action name="login" class="userloginAction" method="Login">
    		    
    		    <result name="success">/success.jsp</result>
    		    <result name="failed">/failed.jsp</result>
    		  </action>
    	    </package>
    	</struts>

spring-hibernate.xml配置：

<bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
    		
    		<property name="url" value="jdbc:mysql://localhost:3306/ssh" />
