插入数据的时候,刚开始没有问题,慢慢的就开始报错...

<property name="hibernate.connection.pool.size">50</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<property name="current_session_context_class">thread</property>
<property name="hibernate.show_sql">true</property>
<property name="connection.autoReconnect">true</property>
<property name="connection.autoReconnectForPools">true</property>
<property name="connection.is-connection-validation-required">true</property>




/**
* 保存数据
* @param news
*/

public static void save(News news) {
		Session session = HibernateSessionFactory.getSession();
		Transaction tx = session.beginTransaction();
		try {
			session.save(news);
			tx.commit();
		}catch(PropertyValueException e){
			//非空约束
		}catch(ConstraintViolationException e){
			//  数据库唯一约束
		} catch (Exception e) {
			System.err.println("入库失败:   " + e);
			e.printStackTrace();
		} finally {
			if (session!=null) {
				session.close();
			}
		}
