Firstly I figured out couple of codes that can cause serious performance issues and is not advised.
Here's a few:
Take off your Generated Getters and Setters and Leave the annotation
@Getter
and
@Setter
to do the work.
Take off
<input type="hidden" th:field="*{add_id}" />
as it will be auto-generated from your entity Address
private Long add_id
Take off
address.toString()
from your
saveAddress
controller as this is not needed to parse data to your Entity, your entity receives String already which will be parsed from your form, there is no need to convert with
toString
again.
One of your error states
Failed to convert from type [java.lang.String] to type [java.lang.Long]
which simply means you're trying to convert Long to String which should be auto generated by your Entity
I hope this helps!!!
