Question

public class UserController {
@Autowired
private UserRepository userRepository;

@GetMapping
public List<User> findAllUsers() {
    return (List<User>) userRepository.findAll();
}

}

This is the code of the controller class

Answer 1

you specified the url in the @RequestMapping("...") annotation

@RequestMapping("url")
public class UserController {
@Autowired
private UserRepository userRepository;

@GetMapping
public List<User> findAllUsers() {
    return (List<User>) userRepository.findAll();
}

and add the @RestController annotation above the class
