如何在使用HibernateValidator违反任何验证规则时显示错误消息？

Question

我正在使用Spring中的Spring和Hibernate验证一个简单的表单（使用SimpleFormController），并在HibernateValidator的帮助下解释here。表格如下。

<%@page contentType="text/html" pageEncoding="UTF-8" %>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form" %>

<form:form method="post" action="Temp.htm" commandName="validationForm">

<table>
    <tr>
        <td>User Name:<font color="red"><form:errors path="userName" /></font></td>
    </tr>

    <tr>
        <td><form:input path="userName" /></td>
    </tr>

    <tr>
        <td>Age:<font color="red"><form:errors path="age" /></font></td>
    </tr>

    <tr>
        <td><form:input path="age" /></td>
    </tr>

    <tr>
        <td>Password:<font color="red"><form:errors path="password" /></font></td>
    </tr>

    <tr>

    <td><form:password path="password" /></td>

    </tr>

    <tr>
        <td><input type="submit" value="Submit" /></td>
    </tr>
    </table>

</form:form>

以下是验证表单字段的命令类。

final public class ValidationForm 
{
    @NotEmpty
    @Size(min = 1, max = 2)
    private String userName;
    @NotNull
    @NumberFormat(style = Style.NUMBER)
    @Min(1)
    @Max(110)
    private Integer age;
    @NotEmpty(message = "Password must not be blank.")
    @Size(min = 1, max = 1, message = "Password must between 1 to 10 Characters.")
    private String password;

    public void setUserName(String userName)
    {
            this.userName = userName;
    }

    public String getUserName()
    {
            return userName;
    }

    public void setAge(Integer age)
    {
            this.age = age;
    }

    public Integer getAge()
    {
            return age;
    }

    public void setPassword(String password)
    {
            this.password = password;
    }

    public String getPassword()
    {
            return password;
    }
}

以下是控制器类Temp。

@SuppressWarnings("deprecation")
final public class Temp extends SimpleFormController
{
    private TempService tempService=null;
    public Temp()
    {
        //setCommandClass(Temp.class);
        setSuccessView("Temp");
        setFormView("Temp");
        setCommandClass(ValidationForm.class);
        setCommandName("validationForm");
    }

    public void setTempService(TempService tempService)
    {
        this.tempService = tempService;
    }

    @Override
    protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, @ModelAttribute("validationForm") @Valid Object command, BindException errors) throws Exception
    {
        ValidationForm validationForm=(ValidationForm) command;        
        tempService.add(validationForm);
        Map<String, Object>model=new HashMap<String, Object>();
        model.put(getCommandName(), new ValidationForm());
        ModelAndView mv=new ModelAndView("Temp", "validationForm", validationForm);
        return mv;
    }

    @Override
    protected ModelAndView showForm(HttpServletRequest request, HttpServletResponse response, BindException errors) throws Exception
    {
        Map<String, Object>model=new HashMap<String, Object>();
        model.put(getCommandName(), new ValidationForm());
        ModelAndView mv=new ModelAndView("Temp", "validationForm", new ValidationForm());
        return mv;
    }
}

dispatchar-servlet.xml文件中有特定的映射。现在，我需要在ValidationForm类中提到的违反验证时显示特定的错误消息，但不显示错误消息。如何使用HibernateValidator？

修改

已配置命令类dispatchar-servlet.xml和控制器类ValidationForm的{​​{1}}文件如下所示。

TempService

以下是实现上述接口的import validators.ValidationForm; public interface TempService { public void add(ValidationForm validationForm); } 类。

TempServiceImpl

我在这里做错了什么？
