Hi guys,
I am also using java.util.Date in my current project, and I have the same
conversion problems as you. I've just written a
piece-of-code-like-hell-no-design-no-thinking Date converters. Of course,
I'm not using them yet, because the code is horrible, but we could polish it
together. Add LOCALE, error logging, a better structure, and so on.
Here is the horrible piece of code for the converters:
----------------------------------------------------------------------
import java.text.*;
import java.util.*;
import org.apache.commons.beanutils.*;
import org.apache.commons.beanutils.converters.StringConverter;
...
/* you need to register your converters with ConvertUtils in some place,
which is pretty easy */
DateConverter dateConverter = new DateConverter();
StringConverterDateDecorator stringDateConverter = new
StringConverterDateDecorator();
ConvertUtils.register(dateConverter, Date.class);
ConvertUtils.register(stringDateConverter, String.class);
...
class DateConverter implements org.apache.commons.beanutils.Converter
{
public Object convert(Class type, Object value)
{
Object returnValue = null;
if (value==null)
return null;
else
if (type==Date.class && value.getClass() == String.class)
{
Date date;
try {
System.out.println("Date convertor called.");
date =
DateFormat.getDateInstance(DateFormat.DEFAULT).parse((String) value);
returnValue = date;
} catch (ParseException e) {
returnValue = null;
}
}
else
returnValue = null;
return returnValue;
}
}
class StringConverterDateDecorator implements
org.apache.commons.beanutils.Converter
{
private static final StringConverter stringConverter = new
StringConverter();
public Object convert(Class type, Object value)
{
Object returnValue = null;
if (value == null)
returnValue = null;
else
if (type==String.class && value.getClass()==Date.class)
{
System.out.println("String convertor called.");
SimpleDateFormat formatter = new
SimpleDateFormat("dd/MM/yyyy");
String s = formatter.format(value);
returnValue = s;
}
else
{
returnValue = stringConverter.convert(type, value);
}
return returnValue;
}
}
----------------------------------------------------------------------
Regards.
Elder

James, I posted myself many times in that thread. That thread does
not answer the question. It deals with java.sql.Date not
java.util.Date and yes Craig does mention about custom Converters
but I'm wondering if others have done that as their solution for
dealing with java.util.Date and BeanUtils, etc.
My apologies.. I've seen so many dupe posts over the last few weeks.. I
jumped in too quick on this one.
James
