PropertyUtils.copyProperties()

Both BeanUtils.copyProperties() and PropertyUtils.copyProperties() are very
useful functions. Is it possible for me to do selective copying of
properties? I want the method (not) to copy some properties.

Is this possible?

Thanks,
Affan

You could use BeanUtils.copyProperty() in order to copy only the 
properties you wish to.

Naily

Use BeanUtils.describe() to create a Map of your source bean
Remove the values your don't need from the Map
Use BeanUtils.populate to copy the properties from the Map to your
destination bean.

For example. Assume you have a bean, of type SourceBean and you don't want
to copy a property called 'unwantedProperty'...

  Map tmp = BeanUtils.describe(source);
  tmp.remove("unwantedProperty");
  DestinationBean dest = new DestinationBean();
  BeanUtils.populate(dest, tmp);

Hope that helps

Steve
