Spring MVC 无效的日期格式错误消息未显示

Question

我在 Spring MVC 3 中的日期验证方面遇到问题

ClientForm.java

 public class ClientForm
 {
      private Date bday = new Date();

      //Getters and setters
 }

在我的控制器中

    @RequestMapping(value = "/save", method = RequestMethod.POST)
public String save(@Valid ClientForm form, BindingResult result)
{
    if(result.hasErrors())
    {
        return "client.form";
    }

    return "redirect:search";
}

messages.properties

client.search.notnumber=Search value must be a number
typeMismatch.java.util.Date = Invalid date

jsp

<form:form action="save.html" method="post" commandName="clientForm">
    <form:input path="bday" cssClass="date-pick dp-applied" />
    <form:errors path="bday" element="label" cssClass="error"/>
</form:form>

“messages.properties”中的其他验证消息工作正常 但是当我故意输入一个无效的日期（即 111/12/2011）

我收到此错误消息

Answer 1

这是一个绑定异常。你定义了一个活页夹吗？如果是，您是否注册了日期编辑？也许你应该检查那个编辑器，你可能有一个错字......日期中的“e”是从哪里来的？对我来说，这似乎是一个转换错误。
