我有一个NetBeans中的Spring框架的Java Web应用程序项目，我试图使用Spring验证。Spring验证
我的应用程序所做的是提出一张支持票。
我已经阅读了几个教程，并且我得到了表单直到填充字段才发送。问题是我无法显示我在“Validator”类中定义的错误消息。
也就是说，如果必填字段未填写，表单不会发送，但错误消息不会出现在任何地方。
有人能告诉我我做错了什么吗？
这是我的代码：
SupportTicket类：
package controller;
public class SupportTicket
{
private String SubmissionStatus;
private String ReportNumber;
private String SupportType;
private String WithContract;
private String Priority;
private String SupportTicketID;
private String CustomerName;
private String SenderName;
private String SenderLastName;
private String ContactMail;
private String ContactPhone;
private String Description;
public String submitTicket()
{
//Do something
}
//setters and getters for private members
public String getContactMail() {
return ContactMail;
}
public void setContactMail(String ContactMail) {
this.ContactMail = ContactMail;
}
public String getContactPhone() {
return ContactPhone;
}
public void setContactPhone(String ContactPhone) {
this.ContactPhone = ContactPhone;
}
public String getCustomerName() {
return CustomerName;
}
public void setCustomerName(String CustomerName) {
this.CustomerName = CustomerName;
}
public String getSenderName() {
return SenderName;
}
public void setSenderName(String SenderName) {
this.SenderName = SenderName;
}
public String getDescription() {
return Description;
}
public void setDescription(String Description) {
this.Description = Description;
}
public String getSubmissionStatus() {
return SubmissionStatus;
}
public void setSubmissionStatus(String SubmissionStatus) {
this.SubmissionStatus = SubmissionStatus;
}
public String getReportNumber() {
return ReportNumber;
}
public void setReportNumber(String ReportNumber) {
this.ReportNumber = ReportNumber;
}
public String getSupportTicketID() {
return SupportTicketID;
}
public void setSupportTicketID(String SupportTicketID) {
this.SupportTicketID = SupportTicketID;
}
public String getPriority() {
return Priority;
}
public void setPriority(String Priority) {
this.Priority = Priority;
}
public String getSupportType() {
return SupportType;
}
public void setSupportType(String SupportType) {
this.SupportType = SupportType;
}
public String getWithContract() {
return WithContract;
}
public void setWithContract(String WithContract) {
this.WithContract = WithContract;
}
public String getSenderLastName() {
return SenderLastName;
}
public void setSenderLastName(String SenderLastName) {
this.SenderLastName = SenderLastName;
}
}
SupportTicketValidator类：
package controller;
import org.springframework.validation.Errors;
import org.springframework.validation.ValidationUtils;
import org.springframework.validation.Validator;
public class SupportTicketValidator implements Validator
{
@Override
public boolean supports(Class aClass)
{
return SupportTicket.class.equals(aClass);
}
@Override
public void validate(Object target, Errors errors)
{
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "SenderName", "SenderName.required", "Sender Name is required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "SenderLastName", "SenderLastName.required", "Sender Last Name is required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "ContactMail", "ContactMail.required", "E-mail is required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "CustomerName", "CustomerName.required", "Customer Name is required");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "ContactPhone", "ContactPhone.required", "Phone is required");
}
}
SupportTicketController类：
package controller;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import service.SupportTicketService;
public class SupportTicketController extends SimpleFormController
{
public SupportTicketController()
{
setCommandClass(SupportTicket.class);
setCommandName("supportTicket");
setSuccessView("resultView");
setFormView("inputView");
}
@Override
protected ModelAndView onSubmit(Object command) throws Exception
{
SupportTicket supportTicket = (SupportTicket)command;
ModelAndView mv = new ModelAndView(getSuccessView());
mv.addObject("SubmissionStatus", supportTicket.submitTicket());
mv.addObject("ReportNumber", supportTicket.getReportNumber());
mv.addObject("CustomerName", supportTicket.getCustomerName());
mv.addObject("SupportType", supportTicket.getSupportType());
mv.addObject("WithContract", supportTicket.getWithContract());
mv.addObject("SenderName", supportTicket.getSenderName());
mv.addObject("SenderLastName", supportTicket.getSenderLastName());
mv.addObject("ContactMail", supportTicket.getContactMail());
mv.addObject("ContactPhone", supportTicket.getContactPhone());
mv.addObject("Description", supportTicket.getDescription());
mv.addObject("Priority", supportTicket.getPriority());
return mv;
}
}

正如我提到的，验证工作（我认为），因为形式是不submited直到我填写所需的字段，但错误消息不显示与<窗体：错误>标签。
你能给我一个建议来解决我的问题吗？
控制器是Spring 2.0风格，如果您没有特定的理由使用这种方式，我强烈建议使用Spring MVC应用程序的Spring 3.0风格。 @见http://viralpatel.net/blogs/2010/06/spring-3-mvc-create-hello-world-application-spring-3-mvc.html – Ralph
