A little doubt about batch update data (Hibernate)

cz88888

A data table userId course score

Where userId and course and dual primary key (this doesn't matter)

I want to update the score value of each piece of data in the table, and use a java function fun (score) that I wrote myself, that is, change the score value to fun (score)

Don't know how to do it

Please give pointers
