404 on setting an association resource [DATAREST-943]

Bert Roos opened DATAREST-943 and commented

My first experiment with Spring Data Rest fails. I've taken the "Getting Started" and modified it a bit to create two entities that have a many-to-one relationships. The entities are Book and Shelve and many books can share a shelve.

The Shelve entity looks like this:

package hello;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class Shelve
{
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;

    private int length;

    public int getLength() {
        return length;
    }

    public void setLength(int length) {
        this.length = length;
    }
}

The Book refers to it:

package hello;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.ManyToOne;

@Entity
public class Book
{
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;

    private String title;

    @ManyToOne
    private Shelve shelve;

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public Shelve getShelve() {
        return shelve;
    }

    public void setShelve(Shelve shelve) {
        this.shelve = shelve;
    }
}

The full project is available here on GitHub.

Now I can add a shelve:

curl -i -X POST -H "Content-Type:application/json" -d "{  \"length\" : \"30\" }" http://localhost:8080/shelves
HTTP/1.1 201
Location: http://localhost:8080/shelves/1
Content-Type: application/hal+json;charset=UTF-8
Transfer-Encoding: chunked

{
  "length" : 30,
  "_links" : {
    "self" : {
      "href" : "http://localhost:8080/shelves/1"
    },
    "shelve" : {
      "href" : "http://localhost:8080/shelves/1"
    }
  }
}

Then a book:

curl -i -X POST -H "Content-Type:application/json" -d "{  \"title\" : \"The Battle of Life\" }" http://localhost:8080/books
HTTP/1.1 201
Location: http://localhost:8080/books/1
Content-Type: application/hal+json;charset=UTF-8
Transfer-Encoding: chunked
Date: Thu, 17 Nov 2016 16:05:02 GMT

{
  "title" : "The Battle of Life",
  "_links" : {
    "self" : {
      "href" : "http://localhost:8080/books/1"
    },
    "book" : {
      "href" : "http://localhost:8080/books/1"
    },
    "shelve" : {
      "href" : "http://localhost:8080/books/1/shelve"
    }
  }
}

Then I try to put the book on the shelve, but that fails:

curl -i -X PUT -H "ContentType: text/uri-list" -d "http://localhost:8080/shelves/1" http://localhost:8080/books/1/shelve
HTTP/1.1 404
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked
Date: Thu, 17 Nov 2016 16:05:02 GMT

{"timestamp":1479398702523,"status":404,"error":"Not Found","message":"No message available","path":"/books/1/shelve"}

I posted this earlier here on StackOverflow. As I suspect an issue in Spring Data Rest, I am posting it here as defect.

Your help is greatly appreciated.
