我在控制器中做了一个微服务，我所需的值来自响应，但它没有显示在postman中，但我postman我得到以下响应
public class Uncategorized {

@Autowired

私人租赁服务租赁服务;

@GetMapping("/{id}")

public ResponseEntity getRental（@PathVariable（“id”）Long id）{ Rental rl = rentalService.findRentalById（id）; return ResponseEntity.ok（rl）;}

@GetMapping("/viewAll")

public List getAllRental（）{ List ls = rentalService.viewAllRental（）; return int n; }
}
public class MyClass {

作为响应，我得到了如图所示的租赁类型值debugger image
但在 Postman 租赁类型中未示出对象。 Postman 回应如下，
{“rentalId”：453，“rentalName”：“Ehsan ulhaq Darrr 1659”，“internalName”：“Khadim Hussain Dar”，“des”：“email protected(https://stackoverflow.com/cdn-cgi/l/email-protection)“，“rentalType”：{}，“rentalSize”：2、“guestAccomodate”：4、“totalUnits”：3）
