Java Spring MVC路由到错误的控制器

我在SpringMVC中有一个web应用程序，登录后我想将它指向/但它总是将我指向/主页

<security:form-login
                login-page="/home/login"
                default-target-url="/"
                always-use-default-target="true"
                authentication-failure-url="/auth/failed"/>

---

登录后，将调用showHome方法而不是loadHome

尝试替换默认目标URL中的/with./error:defaulttarget必须以开头/

@Controller
@RequestMapping(value = "/")
@SessionAttributes({"loginModel"})

    public class HomeController {

        @Autowired
        private LoginModelService loginModelService;

        @RequestMapping(method = RequestMethod.GET)
        public String loadHome(Model model, Principal principal) {

            model.addAttribute("loginModel", loginModelService.getLoginModelByUserLoginName(principal.getName()));
            return "index";
        }

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

            model.addAttribute("loginModel", loginModelService.getLoginModelByUserLoginName(principal.getName()));
            return "system/home";
        }
    }
