Be aware that the new version of Grails 2.3+ supports this type of feature out of the box. See Date Formats for Data Binding

With that said, if you are forced to use a version of Grails prior to 2.3, the CustomEditorRegistrar can be updated using the following code to eliminate the deprecation warning, and also uses the @Component annotation, which allows you to remove / skip the step of adding the bean directly in resources.groovy. Also not that I changed the grails configuration property name to grails.databinding.dateFormats, which matches the property now supported in Grails 2.3+. Finally, my version is a .groovy, not .java file.

import javax.annotation.Resource
import org.codehaus.groovy.grails.commons.GrailsApplication
import org.springframework.beans.PropertyEditorRegistrar
import org.springframework.beans.PropertyEditorRegistry
import org.springframework.stereotype.Component

@Component
public class CustomEditorRegistrar implements PropertyEditorRegistrar {

    @Resource
    GrailsApplication grailsApplication

    public void registerCustomEditors(PropertyEditorRegistry reg){
        def dateFormats = grailsApplication.config.grails.databinding.dateFormats as List
        reg.registerCustomEditor(Date.class, new CustomDateBinder(dateFormats))
    }
}
