问题背景：我需要插入一条数据并且返回主键id，mysql没有问题，oracle多次插入报错丢失参数，重启服务器后又可以插入几条

long meterId = updateWithReturnKey(addSql.toString(), paramMaps, new String[] { "F_METERID"}).longValue();

@Override
    public Number updateWithReturnKey(final String sqlString, Map<String, ?> paramMaps, String[] keyColumnNames) {
        KeyHolder generatedKeyHolder = new GeneratedKeyHolder();
        int rowAffected = -1;
        try {
            rowAffected = getNamedParameterJdbcTemplate().update(sqlString, new MapSqlParameterSource(paramMaps),
                    generatedKeyHolder, keyColumnNames);
        } catch (DataAccessException e) {
            SystemLogger.error("GenericDaoJdbc-updateWithReturnKey-Exception:" + StringUtils.getStackMessage(e));
        }
        return rowAffected > 0 ? generatedKeyHolder.getKey() : -1L;
    }

产生问题的环境中的配置信息：
1：多数据源；
2：数据源有mysql，有oracle；
3：数据源默认为mysql,mysql测试正常；切换数据源到oracle插入数据只能插入一条。插入第二条是就是报出这个错误重启服务便可以再次插入一条数据；

排查问题过程：
1.sql直接插入并无异常；
2.mysql测试没有异常

1. 这两位和我问题差不多

根据这位前辈从德鲁伊换了c3p0依然报错，只是部分插入语句由第二次插入报错，变成了第3次报错，还有些从第五次报错变成了第9次报错。
