on a recent project, I found that all data types of entity classes are strings, no matter what type of oracle database can be inserted and do not need to be converted. Did the bottom layer of jdbc help me convert it?

jdbc should not be converted, just take a look at the sql statement typed in the log.
oralce converts the value of the field when doing insert/select and other operations. If there is no problem with the format of the string, it can be converted to date, number and other types, and the sql statement can be executed normally.
Use caution inselect statements. Indexes are not used when implicit conversions occur.
