java - How to use @Inject in Spring MVC Controller? -

i working spring mvc controller. have 1 of controller datacontroller.

i thinking add httpservletrequest injectable @ top of datacontroller class using @inject.

@controller public class datacontroller {      @inject     httpservletrequest request;      // .. code here      @requestmapping(value = "process", method = requestmethod.get)     public @responsebody     dataresponse processtask(@requestparam("workflow") final string workflow) {          string ipaddress = request.getremoteaddr();         system.out.println(ipaddress);  } 

so question - right way use @inject? have never used @inject before trying learn whether way doing right or not? since everytime, making call processtask method, need grab ipaddress whoever calling processtask method.

in terms of acquiring httpservletrequest: semantically speaking, wrong.

reason: httpservletrequest object created when users send requests , destroyed once requested user action completed. can store way (from syntax angle) shouldn't (from semantic angle). need realize way how web application works not same desktop application (and don't observe them same angle).

suggestion:

@requestmapping(value = "process", method = requestmethod.get) public @responsebody dataresponse processtask(@requestparam("workflow") final string workflow, httpservletrequest request) {...} 

in way corresponding request each time processtask method called. (httpservletrequest object injected @requestmapping.)

(if preserve through out session, consider use bean

suggestion:
@inject private userservice userservice;
(assume have class registered called userservice.)
