Question

我已经建立了一个登录表单。我已经按照教程阅读了有关Spring MVC的验证。

该表单为空白并且不传递任何值，但是不显示任何错误消息。

这是我为控制器编写的代码：

@Controller
public class LoginController {
    @RequestMapping("/login")
    public ModelAndView login() {
    return new ModelAndView("login", "user", new UserModel());
    }

    @RequestMapping("/submitLogin")
    public ModelAndView submitLogin(@Valid UserModel user, BindingResult result) {
        ModelAndView model = new ModelAndView();
        model.addObject("user", user);
        model.setViewName(result.hasErrors() ? "login" : "index");
        return model;
    }
}

这是我的模特

@Data
public class UserModel {
    @NotBlank(message = "The field login name is required")
    private String login;
    @NotBlank(message = "The field password is required")
    private String password;    
}

这是我的表格：

<mvc:form modelAttribute="user" class="col s12" action="/submitLogin" method="POST">
    <div class="container login-form">
        <div class="row">
            <div class="input-field col s12">
                <mvc:input path="login" id="userName" type="text" class="validate" />
                <mvc:label path="login" for="userName">Login name</mvc:label>
            </div>
        </div>
        <div class="row">
            <mvc:errors path="login" cssStyle="color: #ff0000;"/>
        </div>
        <div class="row">
            <div class="input-field col s12">
                <mvc:input path="password" id="password" type="password" class="validate" />
                <mvc:label path="password" for="password">Password</mvc:label>
             </div>
        </div>
        <div class="row">
            <mvc:errors path="password" cssStyle="color: #ff0000;"/>
        </div>
        <div class="row">
            <input type="submit" class="btn waves-effect waves-light pulse green" value="Entrar"/>
        </div>
    </div>
</mvc:form>

我是否错过了Spring Boot或注解的任何配置？

Spring MVC；验证表单的错误消息未显示
