MongoRepository Save method does not insert in database - mongodb

Question

I have created a SpringBoot project with Jhipster. The database I am using is MongoDB.
In the application-dev.yml I have the following configuration:
data:
mongodb:
uri: mongodb://<user>:<pass>#<ip>:<port>
database: gateway
The user, password, ip Address, and port, in my application-dev are real values.
The DatabaseConfiguration.java is:
#Configuration
#EnableMongoRepositories("es.second.cdti.repository")
#Profile("!" + JHipsterConstants.SPRING_PROFILE_CLOUD)
#Import(value = MongoAutoConfiguration.class)
#EnableMongoAuditing(auditorAwareRef = "springSecurityAuditorAware")
public class DatabaseConfiguration {
private final Logger log = LoggerFactory.getLogger(DatabaseConfiguration.class);
#Bean
public ValidatingMongoEventListener validatingMongoEventListener() {
return new ValidatingMongoEventListener(validator());
}
#Bean
public LocalValidatorFactoryBean validator() {
return new LocalValidatorFactoryBean();
}
#Bean
public MongoCustomConversions customConversions() {
List<Converter<?, ?>> converters = new ArrayList<>();
converters.add(DateToZonedDateTimeConverter.INSTANCE);
converters.add(ZonedDateTimeToDateConverter.INSTANCE);
return new MongoCustomConversions(converters);
}
#Bean
public Mongobee mongobee(MongoClient mongoClient, MongoTemplate mongoTemplate, MongoProperties mongoProperties) {
log.debug("Configuring Mongobee");
Mongobee mongobee = new Mongobee(mongoClient);
mongobee.setDbName(mongoProperties.getMongoClientDatabase());
mongobee.setMongoTemplate(mongoTemplate);
// package to scan for migrations
mongobee.setChangeLogsScanPackage("es.second.cdti.config.dbmigrations");
mongobee.setEnabled(true);
return mongobee;
}}
The CloudDatabaseConfiguration is:
#Configuration
#EnableMongoRepositories("es.second.cdti.repository")
#Profile(JHipsterConstants.SPRING_PROFILE_CLOUD)
public class CloudDatabaseConfiguration extends AbstractCloudConfig {
private final Logger log = LoggerFactory.getLogger(CloudDatabaseConfiguration.class);
#Bean
public MongoDbFactory mongoFactory() {
return connectionFactory().mongoDbFactory();
}
#Bean
public LocalValidatorFactoryBean validator() {
return new LocalValidatorFactoryBean();
}
#Bean
public ValidatingMongoEventListener validatingMongoEventListener() {
return new ValidatingMongoEventListener(validator());
}
#Bean
public MongoCustomConversions customConversions() {
List<Converter<?, ?>> converterList = new ArrayList<>();
converterList.add(DateToZonedDateTimeConverter.INSTANCE);
converterList.add(ZonedDateTimeToDateConverter.INSTANCE);
converterList.add(DurationToLongConverter.INSTANCE);
return new MongoCustomConversions(converterList);
}
#Bean
public Mongobee mongobee(MongoDbFactory mongoDbFactory, MongoTemplate mongoTemplate, Cloud cloud) {
log.debug("Configuring Cloud Mongobee");
List<ServiceInfo> matchingServiceInfos = cloud.getServiceInfos(MongoDbFactory.class);
if (matchingServiceInfos.size() != 1) {
throw new CloudException("No unique service matching MongoDbFactory found. Expected 1, found "
+ matchingServiceInfos.size());
}
MongoServiceInfo info = (MongoServiceInfo) matchingServiceInfos.get(0);
Mongobee mongobee = new Mongobee(info.getUri());
mongobee.setDbName(mongoDbFactory.getDb().getName());
mongobee.setMongoTemplate(mongoTemplate);
// package to scan for migrations
mongobee.setChangeLogsScanPackage("es.second.cdti.config.dbmigrations");
mongobee.setEnabled(true);
return mongobee;
}
}
The cdtiApp.java is:
#SpringBootApplication
#EnableConfigurationProperties({ApplicationProperties.class})
public class CdtiApp implements InitializingBean{
private static final Logger log = LoggerFactory.getLogger(CdtiApp.class);
private final Environment env;
public CdtiApp(Environment env) {

The Vehicle entity:
#org.springframework.data.mongodb.core.mapping.Document(collection = "vehicle")
public class Vehicle implements Serializable {
private static final long serialVersionUID = 1L;
#Id
private String id;
#NotNull
#Field("plate")
private String plate;
#NotNull
#Field("registrationDate")
private Instant registrationDate;
#NotNull
#Field("brand")
private String brand;
#NotNull
#Field("model")
private String model;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getPlate() {
return plate;
}
public void setPlate(String plate) {
this.plate = plate;
}
public Instant getRegistrationDate() {
return registrationDate;
}
public void setRegistrationDate(Instant registrationDate) {
this.registrationDate = registrationDate;
}
public String getBrand() {
return brand;
}
public void setBrand(String brand) {
this.brand = brand;
}
public String getModel() {
return model;
}
public void setModel(String model) {
this.model = model;
}
}
The VehicleDTO is:
public class VehicleDTO {
private String id;
private String plate;
private Instant registrationDate;
private String brand;
private String model;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getPlate() {
return plate;
}
public void setPlate(String plate) {
this.plate = plate;
}
public Instant getRegistrationDate() {
return registrationDate;
}
public void setRegistrationDate(Instant registrationDate) {
this.registrationDate = registrationDate;
}
public String getBrand() {
return brand;
}
public void setBrand(String brand) {
this.brand = brand;
}
public String getModel() {
return model;
}
public void setModel(String model) {
this.model = model;
}
}
The VehicleMapper is:
#Mapper(componentModel = "spring")
public interface VehicleMapper{
Vehicle toEntity(VehicleDTO source);
VehicleDTO toDto(Vehicle target);
}
The VehicleResource is:
#RestController
#RequestMapping("/api")
#CrossOrigin(origins = "*", methods = { RequestMethod.GET, RequestMethod.POST })
public class VehicleResource {
private final Logger log = LoggerFactory.getLogger(VehicleResource.class);
#Value("${jhipster.clientApp.name}")
private String applicationName;
#Autowired
private final VehicleService vehicleService;
public VehicleResource(VehicleService vehicleService) {
this.vehicleService = vehicleService;
}
#PostMapping("/vehicle")
#PreAuthorize("hasAuthority(\"" + AuthoritiesConstants.ADMIN + "\")")
public ResponseEntity<Vehicle> createVehicle(#Valid #RequestBody VehicleDTO vehicleDTO) throws URISyntaxException {
log.debug("REST request to save Vehicle : {}", vehicleDTO);
Vehicle newVehicle = vehicleService.createVehicle(vehicleDTO);
return ResponseEntity.created(new URI("/api/vehicle/" + newVehicle.getPlate()))
.headers(HeaderUtil.createAlert(applicationName, "vehicleManagement.created", newVehicle.getPlate()))
.body(newVehicle);
}
}
The VehicleService interface is:
public interface VehicleService {
Vehicle createVehicle(VehicleDTO vehicleDTO);
}
The VehicleServiceImpl is:
#Service
public class VehicleServiceImpl implements VehicleService{
#Autowired
private final VehicleRepository vehicleRepository;
#Autowired
private final VehicleMapper mapper;
public VehicleServiceImpl(VehicleRepository vehicleRepository, VehicleMapper mapper) {
this.vehicleRepository = vehicleRepository;
this.mapper = mapper;
}
private final Logger log = LoggerFactory.getLogger(VehicleServiceImpl.class);
#Override
public Vehicle createVehicle(VehicleDTO vehicleDTO) {
Vehicle vehicle = vehicleRepository.save(mapper.toEntity(vehicleDTO));
log.debug("Created Information for vehicle: {}", vehicle);
return vehicle;
}
}
The VehicleRepository interface is:
/**
* Spring Data MongoDB repository for the {#link Vehicle} entity.
*/
#Repository
public interface VehicleRepository extends MongoRepository<Vehicle, String> {
}
From the Swagger console I access the Vehicle-Resource:
Swagger console
Click on the button and write in the text box the json with the vehicle data:
enter JSON data
As we can see in the following image, the answer is 201. Initially the vehicle was saved with the identifier "id": "60e740935ed5a10e2c2ed19e".
Send request
I access the database to check that the vehicle has been correctly stored in the vehicle table. To my surprise ... there is no vehicle in the vehicle table:
show database
I can make sure that the data in the database application-dev is OK. I don't have any other databases.
I suspect that transactions with the database are not actually being made. This data is somehow stored in memory because if I do a findAllVehicles from Swagger it does return the vehicle.

Answer 1

I have a eureka server running (jhipster-registry) and two microservices that synchronize with it. The Gateway, which acts as a reverse proxy and the Vehiculos microservice. The Swagger console is the gateway, from where I make the request to insert vehicles. Everything seems to work, but as I say in bbdd does not save anything.
