Question

我有以下错误，它给了我应用程序，hibernate 3使用并在我尝试重复访问查询时给了我，我无法将修复程序放在DAOImpl下面并且我多次调用该方法，如果有人可以提供帮助我感谢您的时间：

Exception in thread "AWT-EventQueue-0" 
org.springframework.transaction.CannotCreateTransactionException:
Could not open Hibernate Session for transaction;
nested exception is java.lang.IllegalArgumentException: 
interface org.hibernate.jdbc.ConnectionWrapper is not visible from class loader

方法是

 public void checkattentiontable(){

     for (int i = 0; i < listaoffice.size(); i++) {

      if(i ==0){cantini0 = generalServices.cantAtenttionONtable(listaoffice.get(0));}
      if(i ==1){cantini1 = generalServices.cantAtenttionONtable(listaoffice.get(1));}
      if(i ==2){cantini2 = generalServices.cantAtenttionONtable(listaoffice.get(2));}
      if(i ==3){cantini3 = generalServices.cantAtenttionONtable(listaoffice.get(3));}
      if(i ==4){cantini4 = generalServices.cantAtenttionONtable(listaoffice.get(4));}
      if(i ==5){cantini5 = generalServices.cantAtenttionONtable(listaoffice.get(5));}
      if(i ==6){cantini6 = generalServices.cantAtenttionONtable(listaoffice.get(6));}
      if(i ==7){cantini7 = generalServices.cantAtenttionONtable(listaoffice.get(7));}
      if(i ==8){cantini8 = generalServices.cantAtenttionONtable(listaoffice.get(8));}
     }

     Timer timer = new Timer(5000, new java.awt.event.ActionListener() {

        @Override
        public void actionPerformed(ActionEvent arg0) {

            if (cantinicialofice0 != cantini0) {
                officetoupdate = 0;
                cantinicialofice0 = cantini0;
                updateindicadores(); //INSIDE THIS I ACCESS TO OTHER QUERYS                 
            }


        }
    });

     timer.start();
     timer.setRepeats(true);

 }

如果您正在使用Hibernate 3.2.6 / 3.3.1，则可能是问题的原因是Hibernate中的错误：

<强> HHH-3529: ConnectionWrapper is not visible from class loader

BorrowedConnectionProxy类中有关getProxyClassLoader()方法的错误。

将Hibernate升级到3.5.0或更高版本。如果这不可行，那么您可以申请JIRA中的补丁。

无法为事务打开Hibernate Session：从类加载器中看不到ConnectionWrapper
