我正在使用 jquery 日期选择器在 UI 中提供日期。并提到 dateFormat 为

$( "#validFrmDt" ).datepicker({ dateFormat: "dd-mm-yy" });

对于以下要求的格式：例如：30-09-2013

在我的 spring mvc 模型类中，我希望这种格式与我的 java.util.Date 属性绑定，为此我配置如下：

@DateTimeFormat(pattern = "dd-MM-yyyy")
private Date validFromDate;

但不幸的是，我得到了以下异常：

SEVERE: Servlet.service() for servlet mvc-dispatcher threw exception
org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 2 errors

您需要有一个自定义转换器才能从 String 转换为 java.util.Date 。在您的应用程序上下文中，您可能有这样的事情：

<bean id="customEditorsRegistrar" class="org.springframework.batch.support.DefaultPropertyEditorRegistrar">
    <property name="customEditors" ref="customEditors" />
</bean>

如果这样做，则需要创建自定义编辑器并将其添加到 HashMap 以将转换器从 String 转换为 java.util.Date ：

<bean id="customEditors" class="java.util.HashMap">
    <constructor-arg>
        <map>
            <entry key="java.util.Date">
                <bean class="org.springframework.beans.propertyeditors.CustomDateEditor">
                    <constructor-arg>
                        <bean class="pt.xx.xxxx.xxxx.core.common.support.file.converter.UtilDateFormat" />
                    </constructor-arg>
                    <constructor-arg value="true" />
                </bean>
            </entry>
        </map>
    </constructor-arg>
</bean>
