Java AJAX发布到Webservice REST服务不起作用

我发现了一些与我有关的问题，但没有一个对我有帮助。。。 所以，我有一个webservice，我用它来做这件事。当我尝试使用ajax在上面发布一些数据时，它似乎甚至没有进入我的Web服务（我有Web服务的日志，并且没有出现任何来自任何地方的调用）

这是我的Java类：

 @Path(WebConstants.VEHICLE_URI)
public class VehicleResource extends AbstractResource {

    private static final Logger logger = LoggerFactory.getLogger(VehicleResource.class);


    @POST
    @Path(WebConstants.VEHICLE_GET_BY_USER)
    @Consumes(MediaType.APPLICATION_JSON + CHARSET)
    @Produces(MediaType.APPLICATION_JSON + CHARSET)
    public Response getByUser(VehicleGetListForm form){
        try {
            logger.info("VehicleResource - getForUser - Start get vehicle for user.");
            if (validator.hasErrors(form)) {
                ValidationResponse validationResponse = validator
                        .getFieldErrors(form);
                validationResponse.setMessage(MessageConstants.GENERIC_VALID);
                return Response.ok(validationResponse).build();
            }
            List<ErrorMessage> errors = new ArrayList<ErrorMessage>();

            String[] userTimestamp = rsaEncryption.decrypt(form.getUserTimeStamp()).split("\\ ");
                String userGet = userTimestamp[0];
                String userTime = userTimestamp[1];
                if((userGet.length()<1) || (userGet.length()>64)){
                    ValidationResponse validationResponse = new ValidationResponse();
                    errors = new ArrayList<ErrorMessage>();
                    errors.add(new ErrorMessage("Usuário", MessageConstants.USER_INVALID_MESSAGE));
                    validationResponse.setErrorMessageList(errors);
                    validationResponse.setCode(2);
                    validationResponse.setMessage(MessageConstants.GENERIC_VALID);
                    return Response.ok(validationResponse).build();         
                }else{
                    User user = serviceLocator.getUserService().findByName(userGet);
                    if(user == null){
                        user = saveUser(userGet);           
                    }
                    Long timeGet = Long.valueOf(userTime).longValue();
                    Timestamp timestampGet = new Timestamp(timeGet);                
                    Boolean valid = validatorTimestamp.validateTimestampAuth(user.getDatLastAuth(), timestampGet);

                    if (valid){
                        authUser(user, false);
                        String typeVehicle = "";
                        Integer typeInt = Integer.parseInt(form.getType());
                        if(EnumVehicle.CAR.getValueInt().equals(typeInt))
                            typeVehicle = EnumVehicle.CAR.getValue();
                        else if(EnumVehicle.MOTO.getValueInt().equals(typeInt))
                            typeVehicle = EnumVehicle.MOTO.getValue();
                        else if(EnumVehicle.TRUCK.getValueInt().equals(typeInt))
                            typeVehicle = EnumVehicle.TRUCK.getValue();

                        // Valid type
                        if(typeVehicle.isEmpty()){
                            responseService.setCode(2);
                            responseService.setMessage(MessageConstants.VEHICLE_TYPE_INVALID);
                            return Response.ok(responseService).build();
                        }

                        List<Vehicle> vehicles = serviceLocator.getVehicleService().lisByUser(Integer.parseInt(form.getStart()), Integer.parseInt(form.getRows()), typeVehicle, user);

                        if (vehicles == null || vehicles.size() == 0){
                            responseService.setCode(1);
                            responseService.setMessage(MessageConstants.GENERIC_NOT_FOUND);
                            return Response.ok(responseService).build();
                        }

                        List<VehicleBean> list = VehicleBean.toListBean(vehicles);
                        VehicleReturnBean returnBean = VehicleReturnBean.toBean(list, user.getDatLastUpdate());
                        return Response.ok(returnBean).build();
                    }else{
                        responseService.setCode(2);
                        responseService.setMessage(MessageConstants.USER_INVALID_TIMESTAMP);
                        return Response.ok(responseService).build();
                    }
                }
        } catch (Exception e) {
            logger.error("Error on get all State", e);
            responseService.setException(MessageConstants.GENERIC_ERROR_MESSAGE);
        }

        return Response.ok(responseService).build();
    }

有人知道这里有什么问题吗

非常感谢各位的关注。

我会确保您的服务被正确地托管：1。将get方法添加到web服务，并使用浏览器执行简单的get。2.使用fiddler[（或其他允许您撰写post消息的工具）并将其发布到您的服务方法。3.使用chrome或firefox开发工具逐步完成javascript代码。最后，如果您在chrome或firefox中调试当前代码，您是否在代码中看到警报弹出？我已经尝试过了，找不到任何解决方案：（，无论如何..谢谢：）
