struts配置问题

小弟最近遇到一件极其郁闷的事不废话上代码

<package name="student" extends="struts-default" namespace="/studentMange">
<action name="student" class="StudentAction">
<result name="success">/index.jsp</result>
<result name="updateSuccess">/student/frame/right.jsp</result>
<result name="stuScore">/student/score.jsp</result>
<result name="stuCourse">/student/course.jsp</result>
<result name="getCourse">/student/course_update.jsp</result>
<result name="getCourse2">/student/course_update.jsp</result>
</action>
</package>

<package name="check" extends="struts-default" namespace="/check">
<action name="check" class="CheckAction">
<result name="userCheckSuccess">/student/studentPage.jsp</result>
<result name="teacherCheckSuccess">/teacher/teacherPage.jsp</result>
<result name="fail">/index.jsp</result>
</action>

</package>
这样的配置checkAction中的service总是无法注入导致空指针错误有谁遇到和我一样的错误吗？
我spring配置文件是这样的应该没有问题
    <bean id="CheckAction" class="com.sxt.action.CheckAction" scope="prototype">
    <property name="checkService" ref="checkServiceImpl"></property>
    </bean>
checkAction类的内容
public class CheckAction extends ActionSupport {

CheckService checkService;
//账号
private String stuId;
//密码
private String stuPwd;
//身份
private String role;

public void setCheckService(CheckService checkService) {
System.out.println("注入service");
this.checkService = checkService;
}
总是打印不出注入service这句话
web.xml的配置也是没错的

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/applicationContext.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
--------------------编程问答-------------------- 你web.xml里面配置strust2的配置信息了么？你这里面怎么只有spring的 --------------------编程问答--------------------

+1 --------------------编程问答-------------------- 在struts.xml文件中有没有加
<constant name="struts.objectFactory" value="spring"/>

补充：Java ,  Java EE
