出現上面的報錯，必定要去檢查本身Action的delete方法，若是你從頁面一個只有id值的對象到service層再到dao層。

那麼刪除的時候，就會報上面的錯誤。必定要記住，由於你用的是hibernate刪除，在dao層，你們也都是用的hibernateTemplate來執行對象

 

推薦：org.hibernate.StaleStateException: Batch update returned unexpected row count

[一、a different object with the same identifier value was already associated with the session。　　錯誤緣由：在hibernate中同一個session裏面有了兩個相同標識可是

 

的刪除操做

 

那麼hibernate內部是如何來刪除這個對象呢？  是經過對象來id進行刪除，可是這個對象要已是持久化對象，否則hibernate是不會讓你刪除的。

因此，咱們要刪除一個對象的話，在struts中的action能夠先傳一個id進去，到dao層，在dao層用這個id,用hibernateTemplate.get(Class,id)這個方法從

數據庫取出這個對象，那麼這個對象就是持久化對象了，也就能夠刪除了，hibernate也就不會報這個錯誤了
