Use BeanUtils.cloneBean()
. This method creates a new instance of a
bean with the default constructor, and it copies every property to
the new bean instance. The following instance creates a cloned
instance of a Book
object:
import org.apache.commons.beanutils.BeanUtils;
Book book1 = new Book( );
book1.setName( "Count of Monte Cristo" );
Book book2 = (Book) BeanUtils.cloneBean( book1 );
cloneBean( )
instantiates a new instance of the
bean to be cloned and calls BeanUtils.copyProperties( )
to transfer all readable bean properties to the newly
instantiated bean. The following code demonstrates the steps that
cloneBean( )
is taking to clone an instance of a
bean:
Book book1 = new Book( ); book1.setName( "Practical C Programming" );Book book2 = book1.getClass( ).newInstance( );
PropertyUtils.copyProperties( book2, book1 );
