Assessing the user from within Spring webflow - how to?

[greg.soulsby]

I have tried every approach I can think of to access the currentUser from within Spring webflow.

My user has authenticated via Spring Social LinkedIn.

What would be the strategy?

It is not, for me, <evaluate expression="currentUser" result="currentUser" result-type=""/>

I'm not sure about 'social user', I'll face the issue later, but now for getting 'internal authenticated user' I have something like that in -flow.xml and in Controller class:

    <on-start>
        <evaluate expression="myController.initializeForm(currentUser)" result="flowScope.myForm"/>
         ..........
    </on-start>
......

@Controller
public class MyController {
    @Autowired
    private YourUserService userService;

....
    public FormBeanClass initializeForm(Principal principal) {
......
        FormBeanClass myFormBean = new FormBeanClass()
        if (principal != null && principal.getName() != null) {
            UserXXClass user = userService.findByUserName(principal.getName());
            // most probably user will never be == null, otherwise it won't be authenticated
            ...............
           // do whenever you want
           myFormBean.setUser(...)
           myFormBean.setUserId(.......)
       }
       return myFormBean;
    }

Thanks blandger.

I would never have thought of that. Firstly because I assume (and still do) that there must be a way to directly assess from webflow. But also I am not cleaver enough to think of using a controller like that. I presume @Controller means you get access to the principal.

Thanks again.

You are welcome.

Thanks blandger.

I'm also not so clever as I wanted to be, I found it somewhere.

Yes, that means...

    @RequestMapping(value = "/profile", method = RequestMethod.GET)
    public String profile(Model model, Principal principal) {
.....

Thanks again.

When you need to pass request parameter into web-flow (controller or service class) you can ask me how.
