Özel 'ConversionExecutor', 'shortDate' kimliğine sahip bulunamadı

Question

Bir java yayı web akışında durumu aktarırken bir tarih Dizesini bir java.sql.Date nesnesine dönüştürmek için özel bir dönüştürücü tanımladım. Ancak formu gönderirken aşağıdaki hatayı alıyorum.

Bu hatayı neden aldığımı anlamama yardımcı olabilir misiniz?

4.1.5.RELEASE yay çerçevesi 2.4.2.RELEASE yayı web akışını kullanıyorum.

Dönüştürücü:

import org.springframework.binding.convert.converters.StringToObject; 

import java.text.DateFormat; 
import java.text.SimpleDateFormat; 
import java.text.ParseException; 
import java.sql.Date; 

public class StringToDateTwoWayConverter extends StringToObject { 
    private DateFormat formatter = null; 

    public StringToDateTwoWayConverter() { 
     super(StringToDateTwoWayConverter.class); 
     formatter = new SimpleDateFormat("dd/MM/yyyy"); 
    } 

    @Override 
    protected Object toObject(String string, Class targetClass) throws Exception { 
     Date date = null; 
     try { 
      long parsedDate = formatter.parse(string).getTime(); 
      date = new Date(parsedDate); 
     } catch (ParseException e) { 
      e.printStackTrace(); 
      return null; 
     } 
     return date; 
    } 

    @Override 
    protected String toString(Object object) throws Exception { 
     Date date = (Date) object; 
     return formatter.format(date); 
    } 
} 

conversionService:

import com.housemanagement.converter.StringToDateTwoWayConverter; 
import org.springframework.binding.convert.service.DefaultConversionService; 
import org.springframework.stereotype.Component; 

@Component("conversionService") 
public class ApplicationConversionService extends DefaultConversionService 
{ 
    @Override 
    protected void addDefaultConverters() { 
     super.addDefaultConverters();   
     this.addConverter(new StringToDateTwoWayConverter()); 
     this.addConverter("shortDate", new StringToDateTwoWayConverter()); 
    } 

} 

WebFlow-config.xml

<flow:flow-builder-services id="flowBuilderServices" view-factory-creator="mvcViewFactoryCreator" conversion-service="conversionService" /> 

Formu bağlayıcı

<binding property="dob" converter="shortDate" required="true" />

Answer 1

:

public StringToDateTwoWayConverter() { 
    super(Date.class); 
    formatter = new SimpleDateFormat("dd/MM/yyyy"); 
}
