Cannot get a connection, pool error Timeout waiting for idle object

Cannot get a connection, pool error Timeout waiting for idle object

异常原因

一直有hibernate的session在开启并偿试打开新连接,导致最终没有空闲链接可用.

解决方案

在this.getSession()之后,用完就关掉这个this.getSession().close() ,

因为不close()的话,一个session会一直占用着它拥有的那个连接,于是该连接再也无法被其它新session使用,最终导致数据库的连接用被尽.

GetPendingCallbackDataDaoImpl.java类中代码

try {
//            PreparedStatement prepStmt = SpringUtils.getCommonDao().getCurrentConnection().prepareStatement(sql.toString());
//            SQLQuery query = SpringUtils.getCommonDao().getSessionFactory().openSession().createSQLQuery(sql.toString());
            SQLQuery query = this.getSession().createSQLQuery(sql.toString());
            for (int i = 0; i < parameters.size(); i++)
                query.setString(i, parameters.get(i));
            for (String column : QUERY_COLUMNS)
                query.addScalar(column, Hibernate.STRING);
            query.setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);
            return query.list();
        } catch (Exception e) {
            throw new BusinessServiceException(e);
        }finally{
            this.getSession().close();
        }
