Trouble implementing pagination for a Spring Boot REST API with Hibernate
I'm having a hard time understanding I'm not sure how to approach I've hit a wall trying to I'm sure I'm missing something obvious here, but I've been banging my head against this for hours... I'm currently developing a REST API using Spring Boot 2.6.6 and Hibernate 5.6.3, and I'm running into issues with implementing pagination on my endpoints. I followed the usual approach of using `Pageable` in my repository method, but I'm not seeing the expected results. My API endpoint is designed to return a paged list of users, but when I request the second page, I'm getting back results that seem to be concatenated from the first page rather than the distinct entries. Here’s a snippet of my repository: ```java public interface UserRepository extends JpaRepository<User, Long> { Page<User> findAll(Pageable pageable); } ``` And here's how I'm calling it in my service layer: ```java public Page<User> getUsers(int page, int size) { Pageable pageable = PageRequest.of(page, size); return userRepository.findAll(pageable); } ``` My controller looks like this: ```java @GetMapping("/users") public ResponseEntity<Page<User>> getUsers(@RequestParam(defaultValue = "0") int page, @RequestParam(defaultValue = "10") int size) { return ResponseEntity.ok(userService.getUsers(page, size)); } ``` I’ve tried adjusting the `PageRequest` parameters and verified that the total count of users is correct, but the data returned seems to combine results from multiple pages. The URL I'm using for the request is: `/api/users?page=1&size=10`, and I see that the `totalElements` in the response correctly identifies the total user count, but when I inspect the content of the page, several users are repeated across calls. I've also checked to ensure that my database query is not incorrectly merging records. Could this be an issue with how pagination is configured in Hibernate, or maybe there's something I'm missing with the Spring Data JPA setup? Any insights would be greatly appreciated! Am I missing something obvious? Am I missing something obvious? Cheers for any assistance! My team is using Java for this mobile app. Any suggestions would be helpful.
