Spring 3.1.1.RELEASE を使用しています。次の属性を持つモデルがあります

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

私のJSPでは、

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

ただし、JSP にアクセスするたびに、次のエラーが発生します。時間の「AM/PM」部分に問題があるのはなぜですか?

属性「ラベル」を使用してみてください: http://static.springsource.org/spring/docs/2.0.x/reference/spring-form.tld.html#spring-form.tld.option そして、時間形式があることに注意してください: @DateTimeFormat(pattern = "h:mm:ss a") なので、"8:00 AM" の代わりに "8:00:00 AM" を使用します。

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

これを試して：

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

「8:00 AM」はオプションの名前ではありません。表示したい値とテキストです。

また、「8:00 a」のフォーマット仕様は「h:mm:ss a」ではなく「h:mm a」だと思います。
