Hibernate問題java.lang.Boolean不能轉換爲java.lang.String使用JDK 1.7

我面臨着Hibernate的問題。Hibernate問題java.lang.Boolean不能轉換爲java.lang.String使用JDK 1.7

使用Hibernate 3.2.6和JDK 1.7.0_21

這是問題，因爲來JDK兼容性與Hibernate的版本？

此問題是隨機的。我仍然無法找到重現的步驟。

代碼getEventById

public EventDTO getEventById(Integer eventId,boolean logActivity, Session session)throws Exception { 

    EventDTO event = null; 
    Transaction transaction = null; 
    try { 

     if (session == null) { 
      session = HibernateSessionFactory.getSession(); 
      if(logActivity){ 
       transaction = session.beginTransaction(); 
      } 
     } 

     event = (EventDTO) super.getByPrimaryKey(EventDTO.class, eventId,session); 


     if(transaction!=null){ 
      transaction.commit(); 
     } 

    } catch (HibernateException e) { 
     LOGGER.error(e.getMessage(), e); 
     if(transaction!=null){ 
      transaction.rollback(); 
     } 
     throw e; 
    }catch (Exception e) { 
     LOGGER.error(e.getMessage(), e); 
     if(transaction!=null){ 
      transaction.rollback(); 
     } 
     throw e; 
    } 

    return event; 

}

方法：getByPrimaryKey

protected BaseEventDTO getByPrimaryKey(Class clazz, Integer pk,Session session) throws Exception{ 

    BaseEventDTO dto = null; 
    Transaction tx = null; 

    try { 

     if (session == null) { 
      session = HibernateSessionFactory.getSession(); 
     } 
     dto = (BaseEventDTO) session.get(clazz, pk); 
     return dto; 

    } 
    catch(Exception e){ 
     LOGGER.error(e); 
     if (tx !=null) { 
      tx.rollback(); 
     } 
     throw e; 
    } 
}

顯示您的代碼：com.sibisoft.northstar.events.service.EventSetupService.getEventById（） –

見代碼，我有我的問題 –

JDK

7已經改變Class.getDeclaredMethods()這樣的順序不被保證。 [click here]

您可能在對象映射中有一個屬性，該屬性的getter方法String getProperty()以及Boolean isPropery()會間歇性地導致問題。

休眠3 BasicPropertyAccessor.getterMethod(...)一些時間發現getProperty()和一些時間isProperty()由於getDeclaredMethods()在JDK 7未指定的排序。這會混淆hibernate，它會爲String類型屬性調用Boolean類型方法。

您需要重命名一個方法才能獲得預期結果。 Hibernate的論壇
