Spring Boot Post method not working with @RequestMapping

Question

I am new to spring boot, creating a simple CRUD operations using Rest API. I have written two methods one for GET and POST. Get works fine but when I try to access post method it's not working its shows 404 error.

    @RequestMapping(value = "/create", method = RequestMethod.POST)
    public ResponseEntity<?> addStudent(@RequestBody Employee employee){
        service.saveOrUpdate(employee);
        
        return new ResponseEntity<Object>("added succcessfully", HttpStatus.OK);   
    }

this returns:

{
    
    "status": 404,
    "error": "Not Found",
    "message": "No message available",
    "path": "/api/create"
}

@RestController
@EnableAutoConfiguration
@RequestMapping(value = "/api")
public class EmployeeController{
    
    @Autowired
    EmployeeService service;
    
    @RequestMapping(value = "/create", method = RequestMethod.POST)
    public ResponseEntity<?> createEmployee(@RequestBody Employee employee){
         service.saveOrUpdate(employee);
         return ResponseEntity.ok().body("Added");
    }
        
    @RequestMapping(value = "/list", method = RequestMethod.GET)
    public ResponseEntity<?> list(){
        List<Employee> employee = service.getAllEmployee();
        
        return new ResponseEntity<List<Employee>>(employee, HttpStatus.OK);
    }
