html 部分百里香未显示

Question

我正在尝试创建注册表单。但是当我尝试运行我的代码时，它的一部分没有出现在屏幕上。我使用 thymeleaf 与 Spring MVC 控制器一起工作。我查看了 Thymeleaf 教程、Whosebug 等...但没有看到任何解决方案。请告诉我我做错了什么或在哪里可以阅读有关此问题解决方案的信息。下面是我的 html 代码片段。

P.S。对不起我的英语。

<div class="container" id="container-middle">
    <form class="form-horizontal" role="form" id="register-form" method="post" th:action="@{/post-user-info}" th:object="${user}">
        <h2 id="form-header">Sign up for BlaBla</h2>
        <div class="form-group">
            <label for="login" class="col-sm-5 control-label">Login:</label>
            <div class="col-sm-4">
                <input type="text" id="login" placeholder="Login" class="form-control" th:field="*{login}">
            </div>
        </div>
        <div class="form-group">
            <label for="first-name" class="col-sm-5 control-label">First name:</label>
            <div class="col-sm-4">
                <input type="text" id="first-name" placeholder="First name" class="form-control" th:field="*{firstName}">

Answer 1

我没有将任何模型从控制器传递到模板，所以它无法将任何结果放在那里。

Answer 2

就是这样！像...

public String goAdd(Model model) {
    model.addAttribute(new DtoCustomer());
    return "customer/edit";
}
