Spring Boot include ID field in json

Propably it's very simple but everything what I found is related to Spring Data Rest. I'm using "spring-boot-starter-web" and I can't found any solution...

Here is my entity clas:

@Entity
@Table(name = "buses")
class Bus(
@Id
@JsonProperty("sideNumber")
@JsonInclude
private val sideNumber: Int,
@NotBlank
var longitude: Double,
@NotBlank
var latitude: Double
)


I tried to annotate sideNumber(Id) property with @JsonInclude and @Jsonproperty but with no luck. In my json reponse I only get longitude and latitude...

My controller looks like that.

@RestController
@RequestMapping("/api")
class BusController {

@Autowired
private lateinit var busRepository: BusRepository

@GetMapping("/buses")
fun getAllBuses(): List<Bus> {
return busRepository.findAll()
}

@PostMapping("/buses")
fun createBus(@Valid @RequestBody bus: Bus): Bus {
return busRepository.save(bus)
}

@GetMapping("/buses/{sideNumber}")
fun getBusById(@PathVariable(value = "sideNumber") sideNumber: Long): Bus {
return busRepository.findById(sideNumber)
.orElseThrow { ResourceNotFoundException("Bus", "sideNumber", sideNumber) }
}

@PutMapping("/buses/{sideNumber}")
fun updateBus(@PathVariable(value = "sideNumber") sideNumber: Long,
@Valid @RequestBody newBus: Bus): Bus {

val bus = busRepository.findById(sideNumber)
.orElseThrow { ResourceNotFoundException("Bus", "sideNumber", sideNumber) }

bus.latitude = newBus.latitude
bus.longitude = newBus.longitude

return busRepository.save(bus)
}

@DeleteMapping("/buses/{sideNumber}")
fun deleteBus(@PathVariable(value = "sideNumber") sideNumber: Long): ResponseEntity<*> {
val bus = busRepository.findById(sideNumber)
.orElseThrow { ResourceNotFoundException("Bus", "sideNumber", sideNumber) }

busRepository.delete(bus)

return ResponseEntity.ok().build<Any>()
}
}


It's nothing complicated though. What I have to do to include this sideNumber(id) propety in json response?? Maybe there is some other good practice to achieve that?

Thanks for any help!
