这是我的问题:我开始测试 AppFuse 以了解它是否符合我的需求。
所以我开始创建一个项目(AppFuse 不是 Light 版本,不是多模块项目)。
然后我按照 Persistance 章节中的步骤(使用 Hibernate),创建了我的 bean、daos 和 manager。
第一次尝试:按照指南中的建议,我只是使用 AppFuse 帮助器类(GenericDaoHibernate 和 GenericManager)配置了 dao 和 manager。一切正常。
第二次尝试:我需要创建一个自定义 Dao 和一个自定义 Manager 来处理我的特定业务规则......再次按照教程......现在我遇到了这个让我抓狂的问题:

为什么 ?
我将所有类(控制器、dao、bean、管理器)放在同一个包.webapp 下( .webapp.controller、*.webapp.dao、*.webapp.dao.impl、ecc)
