Spring Data Jpa存储库不将实体保存到数据库

Question

我在使用JPA时遇到了一些困难。我没有得到任何异常，但我不能保存任何东西到数据库。我从Hibernate到Jpa，在那里一切都工作得很好。下面是我的文件

Application.Properties：

logging.level.org.springframework.web=DEBUG
logging.level.ch.generali=DEBUG
logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type=TRACE

spring.datasource.driver-class-name=org.h2.Driver
spring.datasource.username=postgres
spring.datasource.password=1234
spring.datasource.url=jdbc:h2:mem:party;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;MODE=MYSQL
spring.jpa.hibernate.ddl-auto=update

@Getter
@Setter
@Builder
public class NewClientFormWrapper {
   //Entity
   NaturalPerson person;
   //Entity
   Address[] addresses;
   //Entity
   CommunicationChannel[] communicationChannels;

}

存储库：

public interface NaturalPersonRepository extends JpaRepository<NaturalPerson, Integer> {

    Optional<List<NaturalPerson>> getNaturalPersonByFirstname(String inputFirstname);

    Optional<NaturalPerson> getNaturalPersonById(int id);

    void deleteNaturalPersonById(int id);

}

服务：

@RestController
@RequestMapping("/partner")
public class PartnerService {

@Autowired
NaturalPersonRepository naturalPersonRepository;

@PostMapping(value = "/client")
@Transactional
public ResponseEntity<NewClientFormWrapper> newClient(@RequestBody @Valid NewClientFormWrapper 
request) {

    request.getPerson().setAddresses(Arrays.asList(request.getAddresses()));
    request.getPerson().setCommunicationChannels(Arrays.
       asList(request.getCommunicationChannels()));
    NaturalPerson naturalPerson = naturalPersonRepository.save(request.getPerson());

    NewClientFormWrapper response = NewClientFormWrapper.builder()
            .person(naturalPerson)
            .addresses(naturalPerson.getAddresses().toArray(new Address[0]))
            .communicationChannels(naturalPerson.getCommunicationChannels().toArray(new 
             CommunicationChannel[0]))
            .build();
    return ResponseEntity.ok(response);
    }
  }

我在提交表单时得到了200的响应，但在数据库中找不到数据

您使用的是运行时数据库(H2)，因此当您调用APi时，内存中会显示数据。在实际数据库中没有持久化数据。要将数据持久化到实际的数据库中，您需要使用实际的数据库url和驱动程序设置以下属性

spring.datasource.url=jdbc:h2:mem:party;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;MODE=MYSQL
spring.datasource.driver-class-name=org.h2.Driver
