使用Hibernate，Primefaces和Spring更新記錄

我正在使用spring 3hibernate 4​​和primefaces的集成。 在我的數據表我可以insert和delete記錄，但我的更新代碼不起作用，無法更新表和數據庫。我不想使用primefaces cell editor，我想要command button執行更新。但是當我點擊命令按鈕時，它將刪除數據庫和數據表中除personel_id字段外的單元格（字段）。請幫助我獲得正確的代碼。 enter image description here 當我編輯的字段，然後點擊更新按鈕： enter image description here personelDao.java使用Hibernate，Primefaces和Spring更新記錄

僅在方法定義事務性和分配傳播，如果定義「TR ansactional「在課堂上適用於所有方法。

更改爲personelservice.java：

//@Transactional(readOnly=true) 
public class PersonelService implements IPersonelService{ 
    IPersonelDao personeldao; 
    @Transactional(propagation=Propagation.REQUIRED) 
    public void addPersonel(Personel personel) { 
     getPersoneldao().addPersonel(personel); 
    } 

    @Transactional(propagation=Propagation.REQUIRED) 
    public void updatePersonel(Personel personel){ 
     getPersoneldao().updatePersonel(personel); 
    } 

    @Transactional(propagation=Propagation.REQUIRED) 
    public void deletePersonel(Personel personel) { 
     getPersoneldao().deletePersonel(personel); 
    } 
}

親愛的馬努，謝謝你的回覆。我做了你說的，但我的問題沒有解決。 – samira

你設置什麼樣的方式了，在「applicationContext.xml中」對數據庫的訪問？

是的，我可以插入和刪除。但我無法更新。我認爲我的代碼不正確。 – samira

在這種情況下，問題是更新實體的負擔和不在「@ Transactional」相同的定義中。 如果更新尚未加載到相同「@ Transactional」的實體可能未處於會話中，則對於此情況，有兩種選擇： 將@ Transactional置於初始方法「PersonelBean.update（）」中。 在更新之前進行合併，收集返回的對象並在更新後執行。 問候， –

你能告訴我Dao，Service和Personelbean的正確代碼嗎？非常感謝 – samira

防止會話丟失的問題時更新，變化，道：

public class PersonelDao implements IPersonelDao { 
    ... 
    public Personel updatePersonel(Personel personel) { 
     final Session session = getSessionFactory().getCurrentSession(); 
     if(session.contains(personel)){ 
      session.update(personel); 
     } else { 
      personel = (Personel) session.merge(personel); 
     } 
     return personel; 
    } 
    ... 
}

因此如果實體不在會議將被迫將其與合併鏈接。

您還必須檢索合並所返回的對象，您可能必須強制並更改內存中的引用。

親愛的馬努，謝謝你的關注。但它也不起作用。我真的很困惑。當我編輯數據表單元格並單擊更新命令按鈕時，數據從數據庫和數據錶行中消失。 – samira

馬努，我已編輯帖子添加跟蹤。請你看看。特別感謝 – samira

以調試模式啓動它，希望傳遞正確的行，如果它給出錯誤，附加的錯誤和它發生的行。 –
