I have Rest controller on Spring.
Controller:
@RestController
@RequestMapping("/users")
public class Controller {
private UserService userService;
@Autowired
public Controller(UserService userService) {
this.userService = userService;
}
@GetMapping("/all")
public List<User> fethAllUsers() {
return userService.fetchAllUsers();
}
@GetMapping("/{id}")
public User getUser(@PathVariable ObjectId id) {
return userService.fetchUser(id);
}
@PostMapping("/")
public User createUser(@RequestParam String name, @RequestParam String address) {
return userService.createUser(name, address);
}
@DeleteMapping("/{id}")
public void deleteUser(@PathVariable ObjectId id) {
userService.deleteUser(id);
}
}
Service:
@Service
public class UserService {
private UserRepository userRepository;
@Autowired
public UserService(UserRepository userRepository) {
this.userRepository = userRepository;
}
public List<User> fetchAllUsers() {
return userRepository.findAll();
}
public User fetchUser(ObjectId id) {
Optional<User> optionalUser = userRepository.findById(id);
return optionalUser.orElseGet(optionalUser::get);
}
public User createUser(String name, String address) {
User user = new User();
user.setId(ObjectId.get());
user.setName(name);
user.setAddress(address);
return userRepository.save(user);
}
public void deleteUser(ObjectId id) {
userRepository.deleteById(id);
}
}
Repository:
@Repository
public interface UserRepository extends MongoRepository<User, ObjectId> {
}
Entity:
import lombok.Data;
import org.bson.types.ObjectId;
@Data
public class User {
private ObjectId id;
private String name;
private String address;
}
Currently when I use method @GetMapping in Postman (or browser) in response JSON object in get:
[
{
"id": {
"timestamp": 1569940881,
"machineIdentifier": 9478066,
"processIdentifier": 10308,
"counter": 14051396,
"time": 1569940881000,
"date": "2019-10-01T14:41:21.000+0000",
"timeSecond": 1569940881
},
"name": "testName",
"address": "testAddress"
}
]
And in response I need field "id" in String format and looks like:
[
{
"id": "5d936591909fb22844d66844",
"name": "testName",
"address": "testAddress"
}
]
How can I return in response JSON object fielt "id" as ObjectId in String format?
