Spring data rest status 500 for entity with relati

I have two entities with a relation one to many

public class Order {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Long id;

    private String userName;

    private String company;

    @OneToMany(cascade={CascadeType.PERSIST, CascadeType.MERGE})
    @JoinColumn(name="ORDER_ID")
    private List<Item> items;
}



public class Item {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Long id;

    private String name;

    private Long quantity;
}

Both entities have a @RepositoryRestResrouce and when I try to post in the /orders collction a new Order with Items like:

{
  "userName":"Marco",
  "company":"MP",
  "items":[
        {"name":"CD","quantity":"10"},
        {"name":"DVD","quantity":"5"}
   ]
 }

I have an internal server error:

org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Failed to convert from type [java.net.URI] to type [com.example.springdatarest.domain.entity.Item] for value 'name'; nested exception is java.lang.IllegalArgumentException: Cannot resolve URI name.

I know that I can use the association resource but I would like to know how I can create an Order with Items in one single POST.

Just add parameter exported=false to @RepositoryRestResrouce annotation in your Item repo. Then you can create Order with Item in one request:

{
    "userName": "Marco",
    "company": "MP",
    "items": [
        {
             "name": "CD",
             "quantity": "10"
        },
        { 
             "name": "DVD",
             "quantity": "5" 
        }
    ]
}

I recommend you to add cascade = CascadeType.ALL, orphanRemoval = true to items in Order to make items fully managed by Order.

Additional info.

If you want to work with Order and Item independently you can leave all as is but first create you items:

POST http://localhost:8080/items
{
        {
             "name": "CD",
             "quantity": "10"
        },
        { 
             "name": "DVD",
             "quantity": "5" 
        }
}

then create Order that contains them:

POST http://localhost:8080/orders
{
    {
        "userName": "Marco",
        "company": "MP",
        "items": [
            "http://localhost:8080/items/1",
            "http://localhost:8080/items/2"
        ]
    }
}

You use @JoinColumn annotation with items - so I think you must implement synchronization between Order and Items in that case...

And please don't post JSON in one line ))
