Spring REST return byte[] like field in response

Question

I have a class ProductItem

@Data
public class ProductItem {
  private String name;
  private String description;
  private byte[] image;
}

And Spring rest method:

@GetMapping(value = "/test")
private ResponseEntity<ProductItem> findProduct() {
    ProductItem i= service.getProductItem()
    return ResponseEntity.ok(i);
}

How can I correctly return byte[] in this class?

what is issue, it should work, only thing i think is missing is produces in mapping. Your mapping should be @GetMapping(value = "/test", produces = MediaType.APPLICATION_JSON_VALUE) — Yogi

You can base64 encode the byte[] to a String in you ProductItem's field

Or

You can add HttpServletReponse to your method and write the byte[] in the response's OutputStream. In this case no need to return ResponseEntity.
