無法將[java.util.ArrayList]類型的屬性值轉換爲屬性'java.lang.Class []]'annotatedClasses'

我的spring bean數據庫連接myDataSource如下。我得到異常我如何解決這個例外。 RoomUser位於正確的位置。我嘗試更改標籤，但現在使用。無法將[java.util.ArrayList]類型的屬性值轉換爲屬性'java.lang.Class []]'annotatedClasses'

<bean id="mySessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> 
    <property name="dataSource" ref="myDataSource" /> 
    <property name="annotatedClasses"> 
     <list> 
      <value>com.room.user.beans.RoomUser</value> 
      <value>com.room.user.beans.RoomUserType</value> 
     </list> 
    </property> 
    <property name="hibernateProperties"> 
     <props> 
      <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> 
      <prop key="hibernate.show_sql">true</prop> 
     </props> 
    </property> 
</bean>

的例外是：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mySessionFactory' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert property value of type [java.util.ArrayList] to required type [java.lang.Class[]] for property 'annotatedClasses'; nested exception is java.lang.IllegalArgumentException: Cannot find class [com.room.user.beans.RoomUser]

「RoomUser在正確的位置」 - 不，不是，否則這個錯誤不會發生。 – skaffman 2012-03-05 10:41:33

沒有，只有你的模型類的問題。 spring無法在您的application-context.xml文件中找到class RoomUser

<list> 
     <value>com.room.user.beans.RoomUser</value> 
     <value>com.room.user.beans.RoomUserType</value> 
    </list>

我也遇到了同樣的問題。檢查RoomUser是否在正確的包裝中？
