我应该下载什么以及在哪里下载才能在春季与 jsr-303 一起使用？
我应该下载什么来使用 spring.know 注释在我的类中是未知的，例如在下面的代码中：
public String register2( @Valid User user , BindingResult br)
{
if(br.hasErrors())
{
return "edit";
}
//System.out.println("you registers!");
return "thanks";
}
@valid isknown。我应该下载哪个库来使用 spring mcv 中的 jsr-303 标准？我应该在哪里下载？ 我如何在 eclipse helious 中设置它？ 谢谢
编辑：我的代码已附加=>
我的控制器=>
package codes;
import java.util.Map;
import javax.validation.Valid;
import javax.validation.Validator;
import org.apache.jasper.tagplugins.jstl.core.Out;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.Model;

import org.springframework.validation.BindingResultUtils;
import org.springframework.web.bind.annotation.RequestMapping;

@RequestMapping(value="/register/" , method=RequestMethod.GET)
public String register(Model model)
{
model.addAttribute("myUser",new User());
return "edit";
}
@RequestMapping(value="/register/" , method=RequestMethod.POST)
public String register2( ModelAndView model,@Valid User myUser , BindingResult br)
{
try
{
if(br.hasErrors())
{
return "edit";
}
else
{
System.out.println(myUser);
System.out.println(myUser.getName());
System.out.println(myUser.getFamily());
System.out.println("salam");
return "thanks";
}
}
catch (Exception e) {
// TODO: handle exception
System.out.println(e.getMessage());
}
return "thanks";
}
}
我的 edit.jsp 页面（表单）=>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@taglib prefix="sf" uri="http://www.springframework.org/tags/form" %>

<sf:input path="family" id="USER_FAMILY"/>
<br>
<input type="submit" value="REGISTER" />
</sf:form>
</div>
</body>
</html>
注意：只有当我的用户对象无效时，我才会得到异常，而当该用户对象有效时，我不会给出异常
