Question

我正在将我的项目从Spring 2.5.6迁移到Spring 4.0.6。以下是我们拥有的客户属性编辑器的xml定义。

<bean class="org.springframework.beans.factory.config.CustomEditorConfigurer">
<property name="customEditors">
    <map>
    <entry key="org.joda.time.DateTime">
        <bean class="com.om.dh.util.joda.spring.DateTimeEditor">
            <constructor-arg index="0">
                <list>
                    <value>yyyyMMdd</value>
                    <value>yyyy-MM-dd</value>
                </list>
            </constructor-arg>
            <constructor-arg index="1" value="true"/>
        </bean>
    </entry>
    <entry key="org.joda.time.LocalDate">
        <bean class="com.om.dh.util.joda.spring.LocalDateEditor">
            <constructor-arg index="0">
                <list>
                    <value>yyyyMMdd</value>
                    <value>yyyy-MM-dd</value>
                </list>
            </constructor-arg>
            <constructor-arg index="1" value="true"/>
        </bean>
    </entry>
    </map>
 </property>
</bean>

但是，当我启动服务器时，我在日志中看到以下异常。
