我正在使用struts2，spring和hibernate做一个项目。我在struts.xml文件中遇到了一个问题，即它没有接受在applictioncontext.xml中声明的bean。 我的applicationcontext.xml看起来像这个

    <bean id="dvdDAO" class="com.ideas2it.dvdstruts.DvdDAO">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>
<bean id="userDetailDAO" class="com.ideas2it.dvdstruts.UserDetailDAO">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<bean id="hibernatetransactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<bean name="DvdAction" class="com.ideas2it.dvdstruts.DvdAction" >
<property name="dvdDAO" ref="dvdDAO"/>
<property name="userDetailDAO" ref="userDetailDAO"/>
</bean>
<bean name="LoginAction" class="com.ideas2it.dvdstruts.LoginAction" >
<property name="userDetailDAO" ref="userDetailDAO"/>
</bean>

<bean name="AccountCreationAction" class="com.ideas2it.dvdstruts.AccountCreationAction" >
<property name="userDetailDAO" ref="userDetailDAO"/>

我的struts.xml 

<struts>
    <constant name="struts.devMode" value="true" />
    <constant name="struts.enable.SlashesInActionNames" value="true"/>
    <constant name="struts.objectFactory" value="spring"/>
    <package name="basicstruts2" namespace="/" extends="struts-default">
        <action name="register" class="AccountCreationAction" method="register" >
            <result name="success">Login.jsp</result>
            <result name="input">failure.jsp</result>
        </action>
        <action name="login" class="LoginAction" method="loginProcess" >
            <result name="success" type="redirectAction"> 
            <param name="actionName">display</param> 
            <param name="userDetail">${userDetail}</param>
            </result>
            <result name="input">failure.jsp</result>
        </action>
        <action name="insert" class="DvdAction" method="insertDvd">
            <result type="redirectAction">
            <param name="actionName">display</param>
            </result>
        </action>

        <action name="delete" class="DvdAction" method="deleteDvd">
            <result type="redirectAction">
            <param name="actionName">display</param>
            </result>
        </action>

        <action name="update" class="DvdAction" method="updateDvd">
            <result type="redirectAction">
            <param name="actionName">display</param>
            </result>
        </action>

        <action name="display" class="DvdAction" method="displayDvd">
            <result name="success">Dvd.jsp</result>
        </action>


    </package>
</struts>

在applicationcontext.xml中的bean，这里没有引用。我在日志中遇到错误 日志中的错误：

尝试将<beans default-autowire="autodetect">添加到applicationContext.xml，并检查您的图书馆的版本和数量。
