PropertyEditor for java.util.Calendar

[davidkarlsen]

I cannot seem to find support for a PropertyEditor for java.util.Calendar? Haven't I looked thoroughly enough or is it missing?

Calendar.getInstance().getTime() returns Date object

then this is howu use CustomDateEditor class for convertign date strings into java.util.Date properties

First, declare an instance of it in the bean configuration file.

<beans ...>
...
<bean id="dateEditor"
class="org.springframework.beans.propertyeditors.C ustomDateEditor">
<constructor-arg>
<bean class="java.text.SimpleDateFormat">
<constructor-arg value="yyyy-MM-dd" />
</bean>
</constructor-arg>
<constructor-arg value="true" /> // indicates this editor allows empty values.
</bean>
</beans>

Then register this property editor in a CustomEditorConfigurer instance


<beans ...>
...
<bean class="org.springframework.beans.factory.config.Cu stomEditorConfigurer">
<property name="customEditors">
<map>
<entry key="java.util.Date">
<ref local="dateEditor" />
</entry>
</map>
</property>
</bean>

Sure - this will work for string to date, but not string to Calendar - which was my question - so to make the story short - this is not supported by the framework - but no harder than that you extend the existing class, and override the toObject method to return a calendar instead.
