我试图执行一个插入语句，但不幸的是，我无法将数据保存到数据库中。可能是这里的@Query注解不正确。
下面是我的类。控制器：

@Component
//@RequestMapping("/api/v1")
public class EmployeeControllerImpl implements EmployeeController{
    @Autowired
    public EmployeeService employeeService;
    
    @Override
    @PostMapping("/addEmployee")
    public Employee addEmployee(@RequestBody Employee emp) {
        return employeeService.addEmployee(emp);
        }

}

@Component
public class EmployeeServiceImpl implements EmployeeService{
    
    @Autowired
    public EmployeeRepository employeeRepository;
    
    @Override
    public Employee addEmployee(Employee emp) {
    
        return employeeRepository.addEmployee(emp);
    }
}

            + "VALUES (:fname, :lname, :gender, :age, :contactNumber, :empEmail, :empPass)", nativeQuery = true)
