Jax-rs (jersey2) mit Spring Boot @ POST-Methode - 400 Fehler

Question

Ich habe Jax-rs, Spring Boot + JPA, PostgreSQL, JQuery und wenn versuchen, Kunden in @POST Anfrage, bekomme ich 400 Fehler. Alle @ GET ist und @PUT funktionieren Hier Ressource-Methode:

@Path("/customers") 
@Produces(MediaType.APPLICATION_JSON) 
@Consumes(MediaType.APPLICATION_JSON) 
public class CustomerResource { 

    @Autowired 
    private CustomerService customerService; 

... 

@POST 
    public Response createCustomers(CustomersEntity customer, 
            @Context UriInfo uriInfo 
    ){ 
     customerService.save(customer); 
     Long id = customer.getId(); 

     URI createdUri = uriInfo.getAbsolutePathBuilder().path(Long.toString(id)).build(); 
     return Response.created(createdUri).build(); 
    } 

JQuery:

function addCustomer() { 
    console.log('addCustomer'); 
    //add CSRF AJAX/REST protection: 
    //csrfGet.make(); 
    $.ajax({ 
     type: 'POST', 
     contentType: 'application/json', 
     url: customerlistURL, 
     dataType: 'json', 
     data: formToJSON(), 
     success: function(data, textStatus, jqXHR){ 
      alert('Customer created successfully'); 
      $('#btnDeleteCustomer').show(); 
      $('#custId').val(data.id); 
     }, 
     error: function(jqXHR, textStatus, errorThrown){ 
      alert('addCustomer error: ' + textStatus); 
     } 
    }); 
} 

formToJSON():

function formToJSON() { 
    var customerId = $('#custId').val(); 
    return JSON.stringify({ 
     "id": customerId == "" ? null : customerId, 
     "firstname": $('#custFn').val(), 
     "lastname": $('#custLn').val(), 
     "email": $('#custEmail').val(), 
     "dateB": $('#custDb').val(), 
     "pass": $('#custPass').val() 
    }); 
} 

Und ich bekomme diesen Header, wenn ich zu schaffen versuchen in POST-Methode:

firstname: "fn-test1"
   

id: null
   

lastname: "ln-test1"
   

pass: "testTEST12345"
   

Was mache ich falsch in der POST-Methode?

Answer 1

Die Methode funktioniert wie erwartet. Problem war in Testdaten. So sah ich es im Serverprotokoll, wenn ich so etwas schreiben:

@POST 
     public void createCustomer(InputStream in){ 
      CustomersEntity customer = readCustomer(in); 
      System.out.println(customer.toString()); 
      customer.setId(idCounter.incrementAndGet()); 
      customerDB.put(customer.getId(), customer); 
      System.out.println("Created customer " + customer.getId()); 
      System.out.println(customerDB); 
      customerService.save(customer); 
} 

protected CustomersEntity readCustomer(InputStream in) { 
     ObjectMapper mapper = new ObjectMapper(); 
     CustomersEntity customer = new CustomersEntity(); 
     try { 
      customer = mapper.readValue(in, CustomersEntity.class); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     return customer; 
    } 


private Map<Long, CustomersEntity> customerDB = 
      new ConcurrentHashMap<Long, CustomersEntity>(); 
    private AtomicLong idCounter = new AtomicLong();
