Question

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" });

以下所需格式：示例：30-09-2013

在我的spring mvc模型类中，我希望这个格式与我的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例外：

SEVERE: Servlet.service() for servlet mvc-dispatcher threw exception
org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 2 errors
Field error in object 'submitXXXForm' on field 'validFromDate': rejected value [30-09-2013]; codes [typeMismatch.submitXXXForm.validFromDate,typeMismatch.validFromDate,typeMismatch.java.util.Date,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [submitXXXForm.validFromDate,validFromDate]; arguments []; default message [validFromDate]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'java.util.Date' for property 'validFromDate'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [java.util.Date] for property 'validFromDate': no matching editors or conversion strategy found]

我的日期格式配置是否错误。请帮助。

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，您可能有类似这样的内容：

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

如果这样做，您需要创建一个自定义编辑器并将其添加到HashMap，以便从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>
