Hibernate creates table "user" flawlessly, but when I'm inserting some values in Postman e.g POST -> localhost:43441/shipwrecks/add, with application/json header and body:
{
"id2":1,
"name":"name1",
"description":"desc1"
}
And I'm getting: Hibernate: insert into shipwreck (description, id2, name) values (?, ?, ?) in console. When I'm inserting data in mysql manually everything go well. Also GET ->localhost:43563/shipwrecks/list works well. Did I make a mistake in this code? Maybe wrong version of Spring Boot?

Answer 1

You need to specify the POST method for the add method in the Controller. I assume your User object is null and the data that you put in your request body does not reach your service.
