copied!<h2>Grails Version >= 2.3</h2> <p>A setting in <code>Config.groovy</code> defines the date formats which will be used application-wide when binding params to a <code>Date</code></p> <pre><code>grails.databinding.dateFormats = [ 'MMddyyyy', 'yyyy-MM-dd HH:mm:ss.S', "yyyy-MM-dd'T'hh:mm:ss'Z'" ] </code></pre> <p>The formats specified in <code>grails.databinding.dateFormats</code> will be attempted in the order in which they are included in the List.</p> <p>You can override these application-wide formats for an individual command object using <code>@BindingFormat</code></p> <pre><code>import org.grails.databinding.BindingFormat class Person { @BindingFormat('MMddyyyy') Date birthDate } </code></pre> <h2>Grails Version < 2.3</h2> <blockquote> <p>i can't and will not belief that extracting the date by hand is nessesary!</p> </blockquote> <p>Your stubbornness is rewarded, it has been possible to bind a date directly since long before Grails 1.3. The steps are:</p> <p><strong>(1)</strong> Create a class that registers an editor for your date format</p> <pre><code>import org.springframework.beans.PropertyEditorRegistrar import org.springframework.beans.PropertyEditorRegistry import org.springframework.beans.propertyeditors.CustomDateEditor import java.text.SimpleDateFormat public class CustomDateEditorRegistrar implements PropertyEditorRegistrar { public void registerCustomEditors(PropertyEditorRegistry registry) { String dateFormat = 'yyyy/MM/dd' registry.registerCustomEditor(Date, new CustomDateEditor(new SimpleDateFormat(dateFormat), true)) } } </code></pre> <p><strong>(2)</strong> Make Grails aware of this date editor by registering the following bean in <code>grails-app/conf/spring/resources.groovy</code></p> <pre><code>beans = { customPropertyEditorRegistrar(CustomDateEditorRegistrar) } </code></pre> <p><strong>(3)</strong> Now when you send a date in a parameter named <code>foo</code> in the format <code>yyyy/MM/dd</code> it will automatically be bound to a property named <code>foo</code> using either:</p> <pre><code>myDomainObject.properties = params </code></pre> <p>or </p> <pre><code>new MyDomainClass(params) </code></pre>
