代码生成，获取IS_AUTOINCREMENT出现异常

一、该问题的重现步骤是什么？

1. 代码生成，使用Oracle数据库，新增数据库模型设计，选择数据库，则页面超时，查询不到Oracle数据库的所有表数据，控制台抛异常；

二、你期待的结果是什么？实际看到的又是什么？

使用oracle数据库，由于oracle不像mysql数据库一样，表字段存在自增的概念，那么使用oracle数据库进行代码生成，则抛异常，导致前后端超时，则获取不到oracle数据库中的所有表数据，无法生成代码。

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

四、请提供详细的错误堆栈信息，这很重要。

五、若有更多详细信息，请在下面提供。
