java - Spring 4 中的自定义属性编辑器

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。

Caused by: org.springframework.beans.TypeMismatchException: Failed to convert property value of type 'java.util.LinkedHashMap' to required type 'java.util.Map' for property 'customEditors'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [com.om.dh.util.joda.spring.DateTimeEditor] to required type [java.lang.Class] for property 'customEditors[org.joda.time.DateTime]': PropertyEditor [org.springframework.beans.propertyeditors.ClassEditor] returned inappropriate value of type [com.om.dh.util.joda.spring.DateTimeEditor]    at org.springframework.beans.BeanWrapperImpl.convertIfNecessary(BeanWrapperImpl.java:479)    at org.springframework.beans.BeanWrapperImpl.convertForProperty(BeanWrapperImpl.java:511)    at org.springframework.beans.BeanWrapperImpl.convertForProperty(BeanWrapperImpl.java:505)    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.convertForProperty(AbstractAutowireCapableBeanFactory.java:1502)    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1461)    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1197)    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:537)    ... 146 moreCaused by: java.lang.IllegalArgumentException: Cannot convert value of type [com.om.dh.util.joda.spring.DateTimeEditor] to required type [java.lang.Class] for property 'customEditors[org.joda.time.DateTime]': PropertyEditor [org.springframework.beans.propertyeditors.ClassEditor] returned inappropriate value of type [com.om.dh.util.joda.spring.DateTimeEditor]    at org.springframework.beans.TypeConverterDelegate.convertIfNecessary(TypeConverterDelegate.java:263)    at org.springframework.beans.TypeConverterDelegate.convertToTypedMap(TypeConverterDelegate.java:623)    at org.springframework.beans.TypeConverterDelegate.convertIfNecessary(TypeConverterDelegate.java:208)    at org.springframework.beans.BeanWrapperImpl.convertIfNecessary(BeanWrapperImpl.java:459)    ... 152 more

在Spring 2.5.6中customEditors是Map，但在Spring 4.0.6中改为Map, Class>。也许这篇文章可以帮助你:http://codeomitted.com/custompropertyeditor/
