例如:
a,b为对象
BeanUtils.copyProperties(a, b);
BeanUtils是org.springframework.beans.BeanUtils,a拷贝到b
public static void copyProperties(Object source, Object target)//source 源文件,target 目标文件
throws BeansException
{
copyProperties(source, target, null, (String[])null);
}
BeanUtils是org.apache.commons.beanutils.BeanUtils,b拷贝到a
public static void copyProperties(Object dest, Object orig)//dest(英译:“蒸馏”,可理解为空白文件,目标文件),original原始的,源文件
throws IllegalAccessException, InvocationTargetException
{
BeanUtilsBean.getInstance().copyProperties(dest, orig);
}
