我們在我們的應用程序中使用spring，hibernate和mysql。但有時查詢生成CannotAcquireLockException，代碼如下CannotAcquireLockException（Spring，Hibernate，Mysql）
public Ledger[] storeOrUpdateLedgers(Ledger[] ledgers,int iClinicId) throws DataAccessException{

}
for(int i=0;i<ledgerList.size();i++){
getHibernateTemplate().clear();
getHibernateTemplate().saveOrUpdate(ledgerList.get(i));
getHibernateTemplate().flush();
