登录控制层：

@Controller
public class LoginController {

    private static final Logger LOGGER = LoggerFactory.getLogger(LoginController.class);


    @Autowired
    AdminService adminService;

    @GetMapping("/cs")
    public String cs() {
        return "cs";

    @PostMapping("/login")
    @ResponseBody
    public Msg login(String name, String pwd, HttpSession httpSession) {
        name = name.trim();
//        LOGGER.info("{}--{}",name,pwd);
        return adminService.login(name, pwd, httpSession);

    }
}
