调试易

以下是struts2：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd"><struts>

        <action name="index">

                <param name="namespace">/example</param>
            </result>
        </action>
    </package>
 -->
    <!-- Add packages here -->
    <constant name="struts.devMode" value="false" />
    <constant name="struts.i18n.encoding" value="utf-8" />
    <constant name="struts.multipart.maxSize" value="10000000000" />
    <package name="user" namespace="/" extends="struts-default">
<action name="loginUser" class="BbsUserAction" method="login">
<result name="SUCCESS">index.jsp</result>
</action>
    </package>
</struts>
以下是action：
private BbsUserDAO bbsUserDAO;
public BbsUserDAO getUserDao() {
return bbsUserDAO;
}
public void setUserDao(BbsUserDAO bbsUserDAO) {
this.bbsUserDAO = bbsUserDAO;
}
以下是Spring配置文件：
<?xml version="1.0" encoding="UTF-8"?>

</bean>
<bean id="BbsUserDAO" class="dao.BbsUserDAO">

</bean>
<bean id="BbsAllowancesDAO" class="dao.BbsAllowancesDAO">

</property>
</bean>

<bean id="BbsAssistanceDAO" class="dao.BbsAssistanceDAO">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>








<bean id="BbsUserAction" class="action.BbsUserAction" scope="prototype">
<property name="bbsUserDAO" ref="BbsUserDAO"></property> 
</bean> 
</beans>
错误信息是：No setter found for property 'bbsUserDAO' in class 'action.BbsUserAction'
我action里面有get set方法 名字也对 为什么有错误那？
