How to read a parameter in url coming via POST method in spring boot - spring-boot

Question

The application requires driver and their locations to be registered. There are two api's one to register driver and one to save location.
The api's are
POST /api/v1/driver/register/
POST /api/v1/driver/:id/sendLocation/
The first api will request, response structure is as below
Request:
{
"name": "Rakesh123",
"email":"rakesh#abc1.com",
"phone_number":9876899979,
"license_number":"DL12CDRWG1",
"car_number":"DL1T43241"
}
Response:
{
"driverId": 2,
"name": "Rakesh123",
"email": "rakesh#abc1.com",
"phone_number": "9876899979",
"license_number": "DL12CDRWG1",
"car_number": "DL1T43241",
"location": null
}
In the second api, the ":id" will be the driver id received and contains the request body with latitude and longitude
Request:
{
"latitude": 12.972442,
"longitude": 77.580643
}
I am facing problem while reading the ":id" parameter from request. I tried printing the request URI value and that's how the request is coming
/api/v1/driver/$id/sendLocation/
The methods are written as below
1.
#PostMapping("/register")
public ResponseEntity<?> registerDriver(#RequestBody DriverDetails driver){
responseMap = new HashMap<>();
try {
DriverDetails registeredDriver = service.registerDriver(driver);
responseMap.put("driver", registeredDriver);
responseEntity = new ResponseEntity<>(responseMap, HttpStatus.CREATED);
}catch(Exception e) {
responseMap.put("status", "failure");
responseMap.put("reason", e.getMessage());
responseEntity = new ResponseEntity<>(responseMap, HttpStatus.BAD_REQUEST);
}
return responseEntity;
}
#PostMapping("/{id}/sendLocation")
public ResponseEntity<?> saveDriverLocation(#PathVariable String id, #RequestBody Location location){
responseMap = new HashMap<>();
try {
service.addLocation(Integer.parseInt(id), location);
responseMap.put("status", "success");
responseEntity = new ResponseEntity<>(responseMap, HttpStatus.ACCEPTED);
}catch(Exception e) {
responseMap.put("status", "failure");
responseMap.put("reason", e.getMessage());
responseEntity = new ResponseEntity<>(responseMap, HttpStatus.BAD_REQUEST);
}
return responseEntity;
}
Will appreciate help

Your code looks fine to me. Maybe it's a problem with the client that sends the request? Did it realy contains the Id value in the URL?
Here a small example with spring boot that reads the Id and print to console:
DemoApplication.java
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
ExampleController.java
#RestController
#RequestMapping("/api/v1/driver")
public class ExampleController {
/**
* Call this Endpoint with e.g. http://localhost:8080/api/v1/driver/123/sendLocation
*/
#PostMapping("/{id}/sendLocation")
public ResponseEntity saveDriverLocation(#PathVariable String id, #RequestBody String location) {
System.out.println("received id: " + id);
System.out.println("received location: "+ location);
return ResponseEntity.ok().build();
}
}
