我收到以下错误：

在类路径资源[jpaDaoContext.xml]中定义的名称为’org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor＃0’的bean创建时出错：bean的初始化失败；嵌套的异常是org.springframework.beans.factory.BeanCreationException：创建在类路径资源[jpaDaoContext.xml]中定义的名称为’vodEntityManagerFactory’的bean时出错：调用init方法失败；嵌套的异常是javax.persistence.PersistenceException：[PersistenceUnit：vodPersistenceUnit]类或包未找到

我在Google上进行了查看，并被告知选择transaction-type = RESOURCE_LOCAL，但是设置已经是这样。这些设置有什么问题：
