Description
I would like to create such an usage but it seems it is not supported yet. I can also contribute for batch query operations.
@Modifying
@Query("UPDATE DUMMYENTITY SET name = :name WHERE id = :id")
int[] updateName(List<User> users);
I tried to check it is already supported or not but could not find anything.

Research direction
Start by tracing how the @Query and @Modifying annotations currently execute modifying queries, then inspect any existing batch-operation tests. Done should establish whether a method accepting a List can execute the update for each item and return int[] update counts, as shown in the issue.
