在应用程序中，我们将Action类声明为Spring bean。这适用于所有Struts映射。
<bean id="plantAdminApprovalAction" scope="prototype"
class="com.honda.naps.action.padmin.PlantAdminApprovalAction">
<constructor-arg ref="plantAdminAppController" />
<property name="plantAdminApprovalDTO" ref="plantAdminApprovalDTO"></property>
</bean>
我们将此用于多个struts映射
<action name="loadApprovalPlant" class="plantAdminApprovalAction" method="loadNAPSApprovalScreenFinal" >
<result name="success" type="tiles">ApprovalWorkflowPlant</result>
</action>
<action name="loadMandatoryApprovalScreenFinal" class="plantAdminApprovalAction" method="loadMandatoryApprovalScreenFinal" >
<result name="success" type="tiles">MandatoryApprovalWorkflowPlant</result>
</action>
<action name="deleteTransportApprover" class="plantAdminApprovalAction" method="deleteTransportApprover">
<result name="success" type="tiles">ApprovalWorkflowPlant</result>
</action>
<action name="deleteApprover" class="plantAdminApprovalAction" method="deleteApprover">
<result name="success" type="redirect-action">loadMandatoryApprovalScreenFinal</result>
</action>
<action name="insertApprover" class="plantAdminApprovalAction" method="insertApprover">
<result name="success">/jsps/padmin/addApproverMsg.jsp</result>
</action>
<action name="addNonMandateDepartment" class="plantAdminApprovalAction" method="addNonMandateDepartment">
<result name="success">/jsps/padmin/addDepartment.jsp</result>
</action>
<action name="insertDeptApprover" class="plantAdminApprovalAction" method="insertDeptApprover">
<result name="success">/jsps/padmin/addnonmandeptMsg.jsp</result>
</action>
<action name="addApprover" class="plantAdminApprovalAction" method="addApprover">
<result name="success">/jsps/padmin/addApprover.jsp</result>
</action>
<action name="deleteDeptApprover" class="plantAdminApprovalAction" method="deleteDepartmentApprovers">
<result name="success" type="redirect-action">loadApprovalPlant</result>
</action>
在所有动作映射声明中它工作正常，但是一个声明它正在打破并抛出异常：

不幸的是，这并没有发生在Eclipse和Test环境中，但它发生在QA环境中。需要一些关于这个问题的想法和意见。
答案 0 :(得分：1)
引起：java.lang.ClassNotFoundException：PlantAdminApprovalAction
它希望有效的类名（FQCN）用于动作类。例如
<action name="loadApprovalPlant" class="com.honda.naps.action.padmin.PlantAdminApprovalAction" method="loadNAPSApprovalScreenFinal" >
<result name="success" type="tiles">ApprovalWorkflowPlant</result>
</action>
