Spring MVC表单验证不起作用 [英] Spring MVC form validation not working
本文介绍了Spring MVC表单验证不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用Spring 4. 我的表单包含以下变量:
I am using Spring 4. My form contains the following variables:
@NotNull
@Email
private String email;
@NotNull
private String firstName;
@NotNull
private String lastName;
@Digits(fraction = 0, integer = 10)
private String phoneNo;
@NotNull
private String role;
我的控制器:
@Controller
@RequestMapping("/user")
public class UserController {
@RequestMapping(value = "/add", method = RequestMethod.POST)
public ModelAndView add(@ModelAttribute("user") @Valid UserBean user, BindingResult result) {
String message;
if (result.hasErrors() && user != null)
return new ModelAndView("userAdd");
else {
userService.addUser(user);
message = "Successfully added user";
}
return new ModelAndView("success", "message", message);
}
@RequestMapping(value = "/register")
public ModelAndView register(@ModelAttribute("user") UserBean user, BindingResult result) {
List<String> roles = new ArrayList<String>();
roles.add("Receiver");
roles.add("Resolver");
roles.add("Logger");
Map<String, List<String>> model = new HashMap<String, List<String>>();
model.put("roles", roles);
return new ModelAndView("userAdd", "model", model);
}
}
我的jsp:
<c:url var="userAdd" value="user/add.do" />
<sf:form method="post" action="${userAdd}" modelAttribute="user">
<table>
<tr>
<td>First Name</td>
<td><sf:input path="firstName" /><br /> <sf:errors
path="firstName" cssClass="error" /></td>
</tr>
<tr>
<td>Last Name</td>
<td><sf:input path="lastName" /><br /> <sf:errors
path="lastName" cssClass="error" /></td>
</tr>
<tr>
<td>Email</td>
<td><sf:input path="email" /><br /> <sf:errors
path="email" cssClass="error" /></td>
</tr>
<tr>
<td>Phone No.</td>
<td><sf:input path="phoneNo" /><br /> <sf:errors
path="phoneNo" cssClass="error" /></td>
</tr>
<tr>
<td>Role</td>
<td><sf:select path="role" items="${model.roles}" /><br /> <sf:errors
path="role" cssClass="error" /></td>
</tr>
<tr>
<td><input type="submit" value="Submit" /></td>
</tr>
</table>
</sf:form>
当我将输入保留为空白时，该表单将不生效，也不会引发任何错误. BindingResult没有任何错误.
When I leave the the inputs blank, the form does not validate and does not throw any error. The BindingResult does not have any errors in it.

推荐答案
您需要添加
<bean id="myBeansValidator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />
和
<mvc:annotation-driven validator="myBeansValidator">
和
<!-- Hibernate Validator -->
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.2.0.Final</version>
</dependency>
应该工作！
