JPA无效的流标头:32303138 [英] JPA invalid stream header: 32303138
问题描述
我是使用Spring Boot的JPA/Hibernate的新手，并且已经遇到了超过6个小时的错误，这使我发疯.
I'm new with JPA / Hibernate with Spring Boot and I've been facing the same error for over 6hours now, this is driving me crazy.
基本上，所有操作都从此处的我的控制器开始
Basically, it all start at my Controller here
@RestController
@RequestMapping("patientApi")
public class RestPatientController {
public static final Logger LOGGER = LoggerFactory.getLogger(RestPatientController.class);
@Autowired
private PatientService patientService;
[...]
@RequestMapping(value = "/patient/prises_en_charge/{id}", method = RequestMethod.GET)
public ResponseEntity<List<PriseEnCharge>> listAllPrisesEnChargeByPatient(@PathVariable("id") long id) {
Patient currentPatient = patientService.findById(id);
LOGGER.info("Récupération de toutes les prises en charges d'un patient avec id {}", currentPatient);
List<PriseEnCharge> prisesEnCharge = patientService.findAllPrisesEnChargeByPatient(currentPatient);
LOGGER.info("Liste de prises en charge {} ({} elements)", prisesEnCharge, prisesEnCharge.size());
if (prisesEnCharge.isEmpty()) {
LOGGER.debug("La liste des prises en charge est vide");
return new ResponseEntity(HttpStatus.NO_CONTENT);
// You many decide to return HttpStatus.NOT_FOUND
}
return new ResponseEntity<List<PriseEnCharge>>(prisesEnCharge, HttpStatus.OK);
}
}
在其中捕获要获取更多数据的元素的ID.然后，我在服务范围内致电DAO
where I catch the ID of the element I want more data for. I then call the DAO within my service
@Service("patientService")
@Transactional
public class PatientServiceImpl implements PatientService {
@Autowired
private PriseEnChargeDao priseEnChargeDao;
[...]
@Override
public List<PriseEnCharge> findAllPrisesEnChargeByPatient(Patient patient) {
return priseEnChargeDao.findPriseEnChargeByPatient(patient);
}
}
DAO正在
@Repository
public interface PriseEnChargeDao extends JpaRepository<PriseEnCharge, Long> {
@Query("from PriseEnCharge where id_patient = :patient")
public List<PriseEnCharge> findPriseEnChargeByPatient(@Param("patient") Patient patient);
}
无论我尝试了什么，它始终抛出异常"java.io.StreamCorruptedException:无效的流头:32303138".我真的不知道了，我对此感到绝望.
No matter what I tried It keeps throwing exception "java.io.StreamCorruptedException: invalid stream header: 32303138". I honnestly don't know anymore, I'm kinda despaired on that case.
推荐答案
我将在这里进行猜测.如果将32303138解释为十六进制的32位字并将其解码"为ASCII字符，则会得到"2018".在我看来，这就像某种日期字符串的前4个字符.
I am going to make a guess here. If you interpret 32303138 as a 32 bit word in hexadecimal and "decode" it as ASCII characters, you get "2018". That looks to me like the first 4 characters of a date string of some kind.
我的猜测是 something 正在尝试对字符串进行反序列化，就好像它是对象流一样.这意味着数据库架构和休眠映射之间不匹配.
My guess is that something is attempting to deserialize a character string as if it was an object stream. That implies that there is a mismatch between the database schema and the hibernate mappings.
