获取表单的控制器

    @RequestMapping(method = RequestMethod.GET, value = "register")
public String addUser(Model model) {
    if (!model.containsAttribute("wrongLink")) {
        System.out.println("not wrong Link");
        model.addAttribute(new UserBean());
    } else {
        System.out.println("wrong Link");
    }
    return "user/register";
}

发布表单的控制器

@RequestMapping(method = RequestMethod.POST, value = "register")
public String addUser(@Valid UserBean userBean, Model model,
        RedirectAttributes redirectAttrs, BindingResult bindingResult) {
    System.out.println("in addUser form");
    if (bindingResult.hasErrors()) {
        System.out.println("ERROR in user Form");
        return "user/edit";
    }
    return "redirect:/users/" + user.getDisplayName();
}

UserBean类

import org.hibernate.validator.constraints.Email;
public class UserBean {

private Integer id;

@Email(message = "Not a vaild Email Address")
private String email;
//getter and setter
}

表格

<div id="container">
    <sf:form method="POST" modelAttribute="userBean">
            <div class="form">
                <sf:input path="email" type="text" id="email"
                    placeholder="email address" />
                <sf:errors path="email" cssClass="error" />
                <input class="send submit" type="submit" name="submit_first"

            </div>

为什么输入无效电子邮件时会出现此异常，而不是必须执行验证。

在你的控制器的addUser方法中，你的BindingResult需要紧跟在bean之后：

public String addUser(@Valid UserBean userBean, BindingResult bindingResult,
                      Model model, RedirectAttributes redirectAttrs) {
    ...
}

Spring验证异常：BindException
