Spring form:errors 不呈现

Question

我有以下控制器方法：

    @RequestMapping(value = "/admin/addNewAdmin")
    public String adminUsers(@ModelAttribute @Valid TerminalAdmin newAdmin, BindingResult bindingResult, ModelMap model, Principal principal, HttpSession session) {
        if (bindingResult.hasErrors()) {
            ...
            model.addAttribute("newAdmin",newAdmin);            
            return "admin/adminUsers";          
        }
        ....
    }

和以下型号：

Entity
@Table(name = "terminal_admin")
public class TerminalAdmin {

    .....

    @Column(name = "email", nullable = false)
    @Size(max = 255)
    @NotEmpty
    private String email;

}

jsp:

    <form:form modelAttribute="newAdmin" action="/admin/addNewAdmin">
            <div class="line">
                <label for="">email</label>
                <form:input path="email" type="text" name="emal" value=""/>
                !!!<form:errors path="email" cssClass="error"/>!!!
                <div class="clear"></div>
            </div>
    </form:form>

我在表单中输入了空电子邮件

在控制器方法的调试中，我看到 bindingResult 有电子邮件不应该为空的错误。

jsp 呈现为：

<form id="newAdmin" action="/admin/addNewAdmin" method="post">
            <div class="line">
                <label for="">email</label>
                <input id="email" name="email" type="text" value="">
                !!!!!!
                <div class="clear"></div>
            </div>
</form>
