SSH中遇到Exception occurred during

例如下图：

更改配置文件：

applicationContext.xml:

  <bean id="projectTaskDao" class="swust.dao.impl.ProjectTaskDaoImpl" 
p:sessionFactory-ref="sessionFactory"></bean>

  <bean id="projectTaskService" class="swust.service.impl.ProjectTaskServiceImpl" 
p:projectTaskDao-ref="projectTaskDao"></bean>

  <bean id="projectTaskAction" class="swust.action.ProjectTaskAction" 
p:projectTaskService-ref="projectTaskService"  
p:projectService-ref="projectService" scope="prototype"></bean>

重点在

<bean id="projectTaskAction" class="swust.action.ProjectTaskAction" 
p:projectTaskService-ref="projectTaskService"  
p:projectService-ref="projectService" scope="prototype"></bean>

中的
p:projectTaskService-ref = "projectTaskService"
p:projectService-ref = "projectService"
（即projectTackAction中引用了 projectService 和 projectTaskService ）

其实就是在当前的Action中添加需要用到的Service依赖。
