还是spring管理action的问题啊，action不能实例化，求各位帮助

struts.xml
<constant name=”struts.objectFactory” value=”spring“></constant>
<!– struts2的扩展名，例如struts1的时候，用的.do,struts2默认为.action，可以改成其它的，例如.dxd –>
<constant name=”struts.action.extension” value=”action”></constant>
<!– 资源文件 –>
<constant name=”struts.custom.i18n.resources” value=”messageResource”></constant>
<package name=”register1″ namespace=”/” extends=”struts-default”>
<action name=”showIndex”>
<result name=”success”>/WEB-INF/pages/index.jsp</result>
</action>
<action name=”register” class=”registerAction” method=”addUser”>
<result name=”success”>/WEB-INF/pages/welcome.jsp</result>
<result name=”input”>/WEB-INF/pages/error.jsp</result>
</action>
</package>
applicationContext.xml
<bean id=”registerAction” class=”com.broada.demo.action.RegisterAction” scope=”prototype”>
<property name=”userserviceImpl” ref=”userserviceId”></property>
</bean>
<bean id=”userdaoId” class=”com.broada.demo.daoImpl.UserDaoImpl”>
<property name=”sqlMapClient” ref=”sqlMapClient”></property>
</bean>
<bean id=”userserviceId” class=”com.broada.demo.serviceImpl.UserServiceImpl”>
<property name=”userdaoImpl” ref=”userdaoId”/>
</bean>
<bean id=”sqlMapClient” class=”org.springframework.orm.ibatis.SqlMapClientFactoryBean”>
<property name=”configLocation”>
<value>/WEB-INF/ibatis/SqlMapConfig.xml</value>
</property>
<property name=”dataSource”>
<ref bean=”dataSource”/>
</property>

<!– struts2模块 –>
<filter>
<filter-name>struts2</filter-name>
<!– struts2的核心过滤器 –>
