BeanUtils copyProperties API to ignore null and specific propertie

If you want to ignore null-value you have to do it with the following line of code before copying properties:

BeanUtilsBean.getInstance().getConvertUtils().register(false, false, 0);

In case you are using the org.springframework.beans.BeanUtils you can ignore specific properies using the method copyProperties(Object source, Object target, String... ignoreProperties). An example,

BeanUtils.copyProperties(sourceObj, targetObj, "aProperty", "another");
