An error is reported when the project is migrated from mysql to oracle.

There was no error, and there were a lot of problems after migration. I don't know which of the following experts has seen the following problems: 17: 23: 54,967 ERRORBasicPropertyAccessor: 118 mysqloracle migration

There was no error at all. There were a lot of problems after the migration. I don't know which of the following experts have seen the problem:

The purpose is to display the table data.
