Question

我正在使用Spring-boot和thymeleaf，并且试图创建注册页面，但似乎无法从登录页面访问register.html

从控制器中我有以下内容

@Controller
public class LoginController {

    private final UserService userService;

    @Autowired
    public LoginController(UserService userService) {
        this.userService = userService;
    }

    @RequestMapping(value = {"/login"}, method = {GET})
    public ModelAndView login() {
        return new ModelAndView("/login");
    }

    @RequestMapping(value = "/register", method = GET)
    public ModelAndView register() {
        System.out.println("register");
        return new ModelAndView("register").addObject(new User());
    }

对于我的登录页面，它具有此功能，并且可以正确呈现，没有问题

                            <h4>

                            You have entered incorrect credentials please try again
                        </div>
                    </div>
                </div>

        <script src="../static/js/adminlte/adminlte.min.js"></script>
    </body>
</html>

正如我所说的，它工作正常

对于我的注册页面，我有这个

<!DOCTYPE html>
<html xmlns:th="https://www.thymeleaf.org">
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <title>Registration Page</title>
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <link rel="stylesheet"
              href="../static/style/bootstrap/bootstrap.min.css"/>
        <link rel="stylesheet"
              href="../static/style/font-awesome/font-awesome.min.css"/>
        <link rel="stylesheet" href="../static/style/ionicons/ionicons.min.css"/>
        <link rel="stylesheet" href="../static/style/adminlte/AdminLTE.min.css"/>
        <link rel="stylesheet" href="../static/style/skins/skin-yellow.css"/>
        <link rel="stylesheet" href="../static/style/custom.css"/>
    </head>
    <body class="hold-transition register-page">
        <div class="register-box">
            <div class="register-logo">
                <a href="register.html"><b>Registration</b></a>
            </div>

            <div class="card">
                <div class="card-body register-card-body">
                    <p class="login-box-msg">Register a new membership</p>
                    <form th:object="user" method="get">
                        <p>Show something</p>
                    </form>
                </div>
            </div>
        </div>
        <script src="../static/js/jquery/jquery.min.js"></script>
        <script src="../static/js/bootstrap/bootstrap.min.js"></script>
        <script src="../static/js/adminlte/adminlte.min.js"></script>
    </body>
</html>

但是，当我在登录页面中单击<a th:href="@{/register}">Sign Up</a>时，该页面似乎仅刷新而没有进入注册页面，如您所见，我尝试在register()中打印内容LoginContoller的方法，但是即使这不是打印，也告诉我我的方法从未被使用过，在浏览器devtools中仔细检查后，我发现register页面正在返回302图片中显示的状态

我尝试在控制器中使用String返回类型，但这也不起作用。我还尝试获取没有发送任何对象的页面，但这不起作用。

我该如何解决？

我发现了问题，在我的SecurityConfig中引用了错误的页面名称

               .antMatchers(
                        "/static/**",
                        "/forgot/*",
                        "/actuator/*",
                        "/register")//this was wrong

Thymeleaf页面未重定向到另一页面
