Limit and offset with pagination in Spring data - spring

Question

Iam trying the select a random user id from my database, for that, I get the total count of my user table, then generate a random int between 1 and the size of the table, then select a user with offset and limit, but it's not working, i got java.lang.NullPointerException: null .
public interface UserSdRepository extends PagingAndSortingRepository<UserSd, Integer> {
long count();
#Query("SELECT userId from UserSd")
Page<Integer> findAllUserId(Pageable pageable);
}
And this is my pagination implementation :
import org.springframework.data.domain.Pageable;
import org.springframework.data.domain.Sort;
public class OffsetLimitRequest implements Pageable {
private int limit;
private int offset;
public OffsetLimitRequest(int offset, int limit) {
this.limit = limit;
this.offset = offset;
}
#Override
public int getPageNumber() {
return 1;
}
#Override
public int getPageSize() {
return this.limit;
}
#Override
public long getOffset() {
return this.offset;
}
#Override
public Pageable first() {
return null;
}
#Override
public Sort getSort() {
return null;
}
#Override
public Pageable next() {
return null;
}
#Override
public Pageable previousOrFirst() {
return null;
}
#Override
public boolean hasPrevious() {
return false;
}
}
And when I call this from my controller, for exemple :
Page<Integer> ids = userSdRepository.findAllUserId(new OffsetLimitRequest(0,1));
I got java.lang.NullPointerException: null .
java.lang.NullPointerException: null

Thank you

Answer 1

What you could do to solve this particular issue is to change the getSort() method of your OffsetLimitRequest class to provide a non-null instance of Sort, e.g.
#Override
public Sort getSort() {
return Sort.unsorted();
}
