AppFuse - Spring Hibernate - 找不到当前线程的会话

标签: spring hibernate spring-mvc appfuse

这是我的问题:我开始测试AppFuse,以了解它是否适​​合我的需求。

所以我开始创建一个项目(AppFuse不是Light版本,而不是多模块项目)。

然后我按照Persistance章节(使用Hibernate)的步骤,创建我的bean,daos和manager。

首先尝试:按照指南中的建议,我只使用AppFuse帮助程序类(GenericDaoHibernate和GenericManager)配置dao和manager。一切正常。

第二次尝试:我需要创建一个自定义Dao和一个自定义管理器来处理我的特定业务规则...再次按照教程...现在我有这个让我疯狂的问题:

为什么?

我将所有类(控制器,dao,bean,manager)放在同一个包 .webapp( .webapp.controller,* .webapp.dao,* .webapp.dao.impl, ECC)

这可能是一年多前提出的,但我希望我可以帮助别人。

当我开始使用appfuse框架时,我遇到了类似的问题。事实证明,我一直忘记在自定义管理器实现中添加单个参数构造函数。我认为,最重要的部分是将 autowired dao实例传递给父类。

预期的自定义管理器实现示例:

  @Service(“customManager”)
public CustomManagerImpl extends GenericManagerImpl&lt; User,Long&gt;的工具 CustomManager {   
私有 userDAO的userDAO的;   
  
@Autowired   
公共 CustomManagerImpl(userDAO的userDAO的){   
(userDAO的);   
.userDao = userDAO的;   



希望有所帮助。
