Spring MVC - Autowired field from header - spring

Question

I made web service with spring mvc(version 4).
This service used token in http header for authorization.
I want to value in http header bind to field in model class auto.
Is it possible? How can I do?
(See below code and comment)
Controller
#Controller
#RequestMapping(value = "/order")
public class OrderController {
private static final Logger logger = LoggerFactory.getLogger(OrderController.class);
#Autowired
private OrderService orderService;
#RequestMapping(value = "/")
#ResponseBody
public List<Order> getAll() throws Exception {
// I want to remove two line below with auto binding (userToken field in model)
// in all controller using token value
String token = request.getHeader("X-Auth-Token"); // remove~
orderService.setUserToken(token); // remove~
orderService.getAllbyUser()
return items;
}
}
Model(Service)
#Service
public class OrderService {
//#Autowired - is it possible?
private String userToken;
public String setUserToken(String userToken)
{
this.userToken = userToken;
}
public List<Order> getAllbyUser() {
String userId = userMapper.getUserId(userToken);
List<Order> list = orderMapper.getAllbyUser(userId);
return list;
}
}

Answer 1

#Autowire is for Spring to inject beans one to another. If you want to inject a String to a bean you can with the org.springframework.beans.factory.annotation.Value annotation.
For example:
#Value("${user.token}")
private String userToken;
This will make Spring search of the user.token in the VM args and other places (which I don't remember and in some specific order).
But again, as said in my initial comment, from the code you show here it seems to be an error setting this field as it is context specific and the #Service (by default) indicates that the OrderService is a singleton.

In order to read a header value from request, you can use #RequestHeader("X-Auth-Token") in your controller, as shown below:
#RequestMapping(value = "/")
#ResponseBody
public List<Order> getAll(#RequestHeader("X-Auth-Token") String token) throws Exception {
orderService.setUserToken(token); // remove~
orderService.getAllbyUser()
return items;
}
Hope this helps you.
