Why does rollback occur in spring jpa after first find - spring

Question

I'm not sure why rollback occurs after the first find query. The first query perfectly works fine, but rollback constantly occurs if I try to do a query again.
This is the Controller.
//....
#GetMapping("/s-id/{s-id}")
public ResponseEntity<DefaultResponseDto<Object>> findManyBySId(HttpServletRequest servletRequest,
#PathVariable(name = "s-id")
String sId) {
// ...
List<Member> members = memberService.findManyBySpotrightId(spotrightId);
// ....
}
//...
This is the Service.
#Transactional(readOnly = true)
public List<Member> findManyBySId(String spotrightId) {
try {
return memberRepository.findBySpotrightIdContainsAndIsDeletedIsFalse(spotrightId);
} catch (RuntimeException e) {
throw new CustomException(SERVER_ERROR);
}
}
This is the Repository.
public interface MemberRepository extends JpaRepository<Member, Long> {
List<Member> findBySIdContainsAndIsDeletedIsFalse(String sId);
}
This is the error message that I get in the console

Why does the rollback occur? And How do I fix this problem?

Answer 1

I found out that it is a bug from Hibernate. I fixed it by including #Param("sId") to parameter like below.
List<Member> findBySIdContainingAndIsDeletedIsFalse(#Param("sId") String sId);
