spring - 404 on setting an association resource -

my first experiment spring data rest fails. i've taken "getting started" , modified bit create 2 entities have many-to-one relationships. entities book , shelve , many books can share shelve.

the shelve entity looks 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 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 available here in github.

now can add 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 date: thu, 17 nov 2016 16:05:02 gmt  {   "length" : 30,   "_links" : {     "self" : {       "href" : "http://localhost:8080/shelves/1"     },     "shelve" : {       "href" : "http://localhost:8080/shelves/1"     }   } } 

then 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 try put book on shelve, 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"} 

any idea what's going wrong here?

as pointed out oliver gierke on the related jira ticket, issue in curl request. should have hypen in content-type:

curl -i -x put -h "content-type: text/uri-list" -d "http://localhost:8080/shelves/1" http://localhost:8080/books/1/shelve http/1.1 204 date: sat, 19 nov 2016 16:50:24 gmt 

so works expected, provided use right way :)

@oliver: lot!
