Hibernate 无法执行JDBC批处理更新

我对hibernate框架比较熟悉，我试着运行我的第一个hibernate应用程序我遇到了以下异常

例外情况

InsertMain（配置类）

insert

是保留的SQL关键字。不要将其用作表名。也不要使用

user

作为列的名称。

现在JDBC批量更新异常已清除，但我得到了test.product找不到异常如果我手动创建表意味着，我的代码工作正常，代码中的错误是什么，为什么不自动创建表。因为hibernate属性是

hbm2ddl.auto

而不是

hbm2dll.auto

。DLL=动态链接库。DDL=数据定义语言。经过一番思考，我终于接受了你的建议。谢谢：）现在JDBC批量更新异常清除了，但我得到了测试。如果我手动创建表，产品找不到异常意味着，我的代码工作正常，代码中的错误是什么，为什么不自动创建表。因为hibernate属性是
