GenericPool:cleanUp less than minSize objects in the pool min=2 max=50 count=0

异常求救：有个同步数据脚本，从某个服务器数据库同步过来数据，跑着就报这个异常了

事务开启方式：
public static TransactionStatus beginNewTransaction() {
DefaultTransactionDefinition td = new DefaultTransactionDefinition(
TransactionDefinition.PROPAGATION_REQUIRES_NEW);
// td.setReadOnly(true);
TransactionStatus status = getTransactionManager().getTransaction(td);
return status;
}
清除缓存方式：
sysOrgDeptService.getBaseDao().getHibernateSession().flush();
sysOrgDeptService.getBaseDao().getHibernateSession().clear();
一段同步数据脚本 跑着就这样：

具体业务代码是这样： TransactionStatus status = TransactionUtils.beginNewTransaction(); 业务内容XXXXXXXXXXXXXXXXXXX } catch (Exception e) { logger.debug("Department synchronization failed!"); TransactionUtils.getTransactionManager().rollback(status); e.printStackTrace(); } update += 1; TransactionUtils.getTransactionManager().commit(status); //清除hibernate缓存 if(update%50==0){ j++; sysOrgDeptService.getBaseDao().getHibernateSession().flush(); sysOrgDeptService.getBaseDao().getHibernateSession().clear(); System.out.println("更新部门数据:第"+j+"次清理缓存"); }
