Description
With Spring Boot 1.3.7 the following is working, with Spring Boot 1.4.0 not anymore:
You find all the examples in this report at https://github.com/toedter/chatty/
Branches:
master -> Spring Boot 1.3.7 => working
Spring-Boot-1.4.0 -> Spring Boot 1.4.0 => not working
Consider 2 REST resources with repositories: User and ChatMessage
ChatMessage has a relation to user:
@ManyToOne
private User author;
With Spring Boot 1.3.7 it was possible to create a new ChatMessage including a relation to an existing user with one POST request, when http://localhost:8080/api/users/toedter_k points to a valid User resource :
curl 'http://localhost:8080/api/messages' -i -X POST -H 'Content-Type: application/hal+json' -d '{"author":"http://localhost:8080/api/users/toedter_k","text":"Hello!"}'
This call gives the following error when using Spring Boot 1.4.0:
o.s.d.r.w.RepositoryRestExceptionHandler : Could not read document: Can not construct instance of com.toedter.chatty.server.boot.user.User: no String-argument constructor/factory method to deserialize from String value ('http://localhost:8080/api/users/toedter_k')
