struts2、spring、およびhibernateを使用してプロジェクトを行っています。struts.xmlファイルで、applictioncontext.xmlで宣言されているBeanを取得していないという問題に直面しました。私のapplicationcontext.xmlは次のようになります
<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"/>
私の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>
ここでは参照されていない applicationcontext.xml にある Bean です。ログに次のようなエラーが表示されます。
