As of Spring 2.0, the recommended usage is to use custom PropertyEditorRegistrar implementations that in turn register any desired editors on a given registry . Each PropertyEditorRegistrar can register any number of custom editors.

 <bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="propertyEditorRegistrars">
     <list>
       <bean class="mypackage.MyCustomDateEditorRegistrar"/>
       <bean class="mypackage.MyObjectEditorRegistrar"/>
     </list>
   </property>
 </bean>

Alternative configuration example with custom editor classes:

 <bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="customEditors">
     <map>
       <entry key="java.util.Date" value="mypackage.MyCustomDateEditor"/>
       <entry key="mypackage.MyObject" value="mypackage.MyObjectEditor"/>
     </map>
   </property>
 </bean>

Also supports "java.lang.String[]"-style array class names and primitive class names (e.g. "boolean"). Delegates to ClassUtils for actual class name resolution.

NOTE: Custom property editors registered with this configurer do not apply to data binding. Custom editors for data binding need to be registered on the DataBinder : Use a common base class or delegate to common PropertyEditorRegistrar implementations to reuse editor registration there.
