Question

Now I have a class User, I get a request data of an array from the jsp or html.

list this Integer[] arr=[5,6,9,10,62,52,21]

Answer 1

if your repository interface extends CrudRepository, you can simply use deleteAll(List< User > entities). No such query is required.

1. get List< User > by using findAllById(ids)

2. deleteAll(List< User > entities)
