getting ApplicationContext with annotations

[SpringingSpringles]

How do I get hold of ApplicationContext in my controller which is plain class with @Controller annotation?


@Controller
@RequestMapping("/systemInfo.do")
public class SystemInfoController {

@RequestMapping(method = RequestMethod.GET)
public String getSystemInfo(ModelMap model,
WebApplicationContext webApplicationContext) {
return "SystemInfo";
}

}

Here is the error message:

Do I need to just implement ApplicationContextAware interface?

Hi SpringingSpringles,

Can I ask, why do you need access to the application context in your controller?
