這是我的問題:我開始測試AppFuse以瞭解它是否適​​合我的需求。AppFuse - Spring Hibernate - 找不到當前線程的會話

所以我開始創建一個項目(AppFuse不是Light版本,不是多模塊項目)。

然後我從Persistant章節(使用Hibernate)開始,創建我的beans,daos和manager。

第一次嘗試:按照指南中的建議,我簡單地使用AppFuse助手類(GenericDaoHibernate和GenericManager)配置了dao和manager。一切正常。

第二個嘗試:我需要創建一個自定義道和一個自定義的經理來處理我的具體業務規則...教程後再次...現在我有這個問題是讓我瘋了:

爲什麼?

我把所有的類(控制器,DAO,豆類,經理)相同的封裝.webapp下( .webapp.controller,* .webapp.dao,* .webapp.dao.impl,ECC)

你的FornitoreController看起來像什麼?換句話說,你如何注入GenericManager? –

嗨馬特,在這裏我的控制器https://code.google.com/p/certificati/source/browse/trunk/src/main/java/com/alessandrodonato/webapp/controller/FornitoreController.java – AlexD

如果您使用Autowired的資源,它的工作? –

這可能是一年多以前問過的,但我希望我可以幫助某人。

我開始使用appfuse框架時遇到了類似的問題。事實證明,我一直忘記在我的自定義管理器實現中添加單個參數構造函數。我認爲,最重要的部分是將autowired dao實例傳遞給父類。

預期定製經理實現的例子:

@Service( 「customManager」)
公共     CustomManagerImpl   延伸   GenericManagerImpl <用戶, 龍>   實現   CustomManager   {
        private   userDao   userDao;
       
        @Autowired
        公共   CustomManagerImpl(userDAO的  userDAO的){
                (U serDao);
                .userDao   =   userDAO的;
       }}

希望有所幫助。
