我正在使用 Spring 3.1.1.RELEASE。我有一个具有以下属性的模型

@DateTimeFormat(pattern = "h:mm:ss a")
private java.util.Date meetingTime;

在我的 JSP 上，我有

                        <form:select path="meetingTime">
                            <form:option value="8:00 AM" name="8:00 AM" />
                        </form:select>

但是，每当我访问我的 JSP 时，我都会收到以下错误。任何想法为什么它在“上午/下午”部分有问题？

尝试这个：

                     <form:select path="meetingTime">
                        <form:option value="8:00 AM">8:00 AM</form:option>
                     </form:select>

“8:00 AM”不是选项的名称；它是您希望显示的值和文本。

另外，我相信“8:00 a”的格式规范是“h:mm a”，而不是“h:mm:ss a”。

尝试使用属性“标签”： http ://static.springsource.org/spring/docs/2.0.x/reference/spring-form.tld.html#spring-form.tld.option 并注意你有时间格式：@DateTimeFormat(pattern = "h:mm:ss a") 所以使用“8:00:00 AM”而不是“8:00 AM”：

<form:select path="meetingTime">
   <form:option value="8:00:00 AM" label="8:00 AM" />
</form:select>
