Java “error”: “Not Found”, “message”: “No message available”,

Question

I work with a small Spring app where I have few values in the database and I would like to retrieve them using the mutable call.

The API is here,

@RestController
@RequestMapping("/api/v1/products")
public class ProductAPI {

    private ProductService service;

    @Autowired
    public void setService(ProductService service) {
        this.service = service;
    }


@GetMapping("/stock/")
public ResponseEntity<Product> findById(@RequestParam("productId") String productId) {

    Product product = service.findById(productId).get();
    return ResponseEntity.of(Optional.of(product));
}

...........
}

The service call,

@Service
public class ProductService {


 private ProductRepository repository;

    @Autowired
    public void setProductRepository(ProductRepository productRepository) {
        this.repository = productRepository;
    }

    public Optional<Product> findById(String id) {

       return repository.findById(id);
    }
}

The repository class,

@Repository
 public interface ProductRepository extends CrudRepository<Product, String>{


 }

When I make the call using the cURL, I get the message,

   $ curl -X GET http://localhost:8080/api/v1/products/stock?productId=Product%20ID | jq
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   142    0   142    0     0    845      0 --:--:-- --:--:-- --:--:--   850
{
  "timestamp": "2019-02-25T12:19:31.797+0000",
  "status": 404,
  "error": "Not Found",
  "message": "No message available",
  "path": "/api/v1/products/stock"
}

I have the entries in the database inserted correctly. What is the issue here?

Answer 1

Because you have extra / in your mapping

@GetMapping("/stock/")

so if you want request like this

curl -X GET http://localhost:8080/api/v1/products/stock/?productId=Product%20ID

you need mapping like:

@GetMapping("/stock")

in you current version right curl looks like:

http://localhost:8080/api/v1/products/stock/?productId=Product%20ID

Answer 2

Since you have clearly mentioned the mapping as @GetMapping("/stock/") in your controller, and when you are trying to access the resource by the path /stock obviously there is no such mapping. Due to that, you are getting 404 found exception.

So, update the mapping like @GetMapping("/stock").
