java - Spring MVC 无效日期格式错误消息未显示

Question

我在 Spring MVC 3 中遇到日期验证问题

客户端窗体.java

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

      //Getters and setters
 }

在我的 Controller 中

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

    return "redirect:search";
}

消息.属性

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无效日期(即 111/12/2011)时

我收到了这个错误信息

Answer 1

这是一个绑定(bind)异常。你有没有定义一个 Binder ？如果是，您是否注册了日期编辑器？也许你应该检查那个编辑器，你可能在那里有错字......日期中的'e'来自哪里？对我来说这似乎是一个转换错误。
