java—为什么我在测试启动时只将类Map到表，却收到关于更改表失败的消息？

在测试开始时，我将许多表从oracledbMap到java类。刚才我只运行了一个测试查询，它运行正常(谢谢你！）
我打开了这些消息，在上下文创建和表Map阶段，我不仅看到了许多成功的表发现，而且最终看到了一些消息，例如：

TST-[2020/12/02 23:58:53.715] hbm2ddl.SchemaUpdate HHH000388: Unsuccessful: alter table CIS_LOKAL_ROLE_AAA add KOD_LOKAL_ROLA_AAA varchar2(10 char) not null
TST-[2020/12/02 23:58:53.715] hbm2ddl.SchemaUpdate ORA-01758: table must be empty to add mandatory (NOT NULL) column

TST-[2020/12/02 23:58:53.881] hbm2ddl.SchemaUpdate HHH000388: Unsuccessful: alter table P01_OPRAVNENI add constraint FK_c0cufehvbvpf9y3dh0fcjrhak foreign key (ID_OBJEKTU) references R01_RIZENI
TST-[2020/12/02 23:58:53.881] hbm2ddl.SchemaUpdate ORA-02298: cannot validate (SPR.FK_C0CUFEHVBVPF9Y3DH0FCJRHAK) - parent keys not found

为什么hibernate要在Map时更改表？
请注意，这里也有关于类似消息的问题，但是它们涉及到表确实要被修改和失败的情况。虽然我不想修改它们，但唯一的查询是关于计数查询的，这是成功的，并且是在我正在写的问题之后出现的。
