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，即它没有采用在 applictioncontext.xml 中声明的 bean。我的 applicationcontext.xml 看起来像这样

    <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>

此处未提及的 applicationcontext.xml 中的 bean。我在日志中收到错误，例如日志中的错误：

尝试添加<beans default-autowire="autodetect">，applicationContext.xml并检查您的库的版本和数量。
