[英]Spring Data JPA + Lombok = UnsupportedOperationException during saving
[英]Pagination - UnsupportedOperationException while accessing to the second page using Spring Data JPA
我想在當前應用程序中添加分頁。 為此,我有以下代碼:
MyEntity.java
@Entity
@Table(name="MY_ENTITY_1")
public class MyEntity {
@Id
@GeneratedValue
@Column(name="P_ID")
private Integer id;
@Column(name = "C_CODEBRANCHE")
private Integer codeBranche;
// ...
}
MyEntityRepository.java
@Repository
public interface MyEntityRepository extends JpaRepository<MyEntity, Integer> {
}
MyServiceImpl.java
@Service
@Transactional
public class MyServiceImpl implements MyService {
@Autowired
private MyEntityRepository myEntityRepository;
@Override
public Page<MyEntity> getEntities(Pageable pageable) {
return myEntityRepository.findAll(pageable);
}
}
還有MyResource.java
@RestController
@RequestMapping("/")
public class MyResource {
@Autowired
private MyService myService;
@GetMapping(path = "/myentity")
public Page<MyEntity> getEntities(Pageable pageable) {
return myService.getEntities(pageable);
}
}
當我稱“ / myentity”時,我有20個結果,這很正常。
當我叫“ / myentity?page = 0&size = 10”時,我有10條結果。
但是,當我呼叫“ / myentity?page = 1&size = 10”時,出現以下問題:
錯誤6864 --- [nio-8082-exec-1] oaccC [。[。[/]。[dispatcherServlet]:路徑為[]的Servlet [dispatcherServlet]的Servlet.service()引發異常[請求處理失敗; 嵌套的異常是java.lang.UnsupportedOperationException:不支持查詢結果偏移量]並有根本原因

我真的不知道怎么回事。
也許您遇到了此錯誤HHH-10489 。 此錯誤已在Hibernate 5.2.4.Final中修復,然后應將Hibernate更新到該版本或更高版本。
將其放在您的application.yml中:
春天:jpa:屬性:休眠:legacy_limit_handler:true
