#21926

Describe the feature you would like.

At present, the AbstractJDBCRowsLoader#loadRowValue method seems to only consider the corresponding relationship between SQL Type and Java Type in MySQL, and does not correctly handle other databases such as PostgreSQL and openGauss. Therefore, java.sql.SQLException: Unknown exception: java.lang.Integer cannot be cast to java.lang.Short appeared in #21926, and we need to adapt to different database dialects.

Also, I looked at the JDBC specification, it specifies the mapping between JDBC Type and Java Type, and most databases are implemented based on the specification, so we can implement these common methods in abstract classes.
