春天安全
原标题:Spring security accessing principal

在使用春天安全时,特别是使用“通知”;在主计长中,谁能接触主人? 请允许我说,我的控制者是我的控制者,但我想在某些地方用安全(安全)方法接触主人。

@Controller
public class LoginController {

    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public String login(ModelMap map, @RequestParam(value="fail" , required=false) String fail){
        map.addAttribute("title", "Login: AD Credentials");
        if(fail != null){
            map.addAttribute("error", "Invalid credentials");
        }
        return("login");
    }

    @RequestMapping("/secure")
    @PreAuthorize("isAuthenticated()")
    public String secure(ModelMap map, String principal){
        System.out.println(principal);
        return("secure");
    }


}

最容易的是 SecurityContextHolder.getContext().getAuthentication(......)。 通过校对模式施工。
