Lombok generated constructor not found for deserialization on POST requests [DATAREST-884]

Kai Tödter opened DATAREST-884 and commented

With Spring Boot 1.3.7 the following is working, with Spring Boot 1.4.0 not anymore:

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')

    @Test
    public void messagesCreateExample() throws Exception {

        user.put("id", "toedter_k");
        user.put("fullName", "toedter_k");
        user.put("email", "kai@toedter.com");

        String userLocation = this.mockMvc
                .perform(
                        post("/api/users").contentType(MediaTypes.HAL_JSON).content(

                .andExpect(status().isCreated()).andReturn().getResponse()
                .getHeader("Location");

        Map<String, Object> chatMessage = new HashMap<String, Object>();
        chatMessage.put("text", "Hello!");
        chatMessage.put("author", userLocation);

        this.mockMvc.perform(
                post("/api/messages").contentType(MediaTypes.HAL_JSON).content(
                        this.objectMapper.writeValueAsString(chatMessage))).andExpect(
                status().isCreated())
                .andDo(document("messages-create-example",
                        requestFields(
                                fieldWithPath("text").description("The text of the chat message"),
                                fieldWithPath("author").description("The author of the chat message. This must be the URL to an existing user resource."))));
