如何使用 SpringBoot REST 解决 postman 中的错误 404？

Question

I am new to spring boot and i have been trying to get a simple api request via postman. But, I am stuck with an error 404. Can someone point the errors in my code?.

I have a spring boot simple app build with maven and run in embedded tomcat through STS. I tried to send this request

http://localhost:8080/api/vi/menu/getAll

Here is my controller code:

@RestController
@RequestMapping("/api/v1/menu")
public class MenuController {
  @Autowired
  private MenuRepository menuRepository;

  @GetMapping
  @RequestMapping("/getAll")
  public List<Menu> list() {
    return menuRepository.findAll();
  }
 }

MenuRepository:

public interface MenuRepository extends JpaRepository<Menu, Integer> {}

The error status in postman:

{ "timestamp": "2022-08-05T04:46:28.489+00:00", "status": 404, "error": "Not Found", "path": "/api/vi/menu/getAll" }

The port is in default 8080.

I tried adding url to the getmapping after referring some online documentations, but still the error 404 is not resolved. Can someone point the error and explain me?

Thanks.

Answer 1

You are calling wrong URL

   /api/vi/menu/getAll

correct url is

     /api/v1/menu/getAll

Change vi to v1
