Conversion of DTO to entity and vice-versa

Question

I am using Spring MVC architecture with JPA in my web application. Where to convert data transfer object (DTO) to JPA entity and vice-versa, manua

Answer 1

I suggest another approach without extra dependency:

import org.springframework.beans.BeanUtils
...
BeanUtils.copyProperties(sourceObject, targetObject);

Can be used to convert DTO to entity, or vice-versa, if they have same property types and names.

If you want to ignore some fields, just add them after the targetObject.

BeanUtils.copyProperties(sourceObj, targetObj, "propertyToIgnoreA", "propertyToIgnoreB", "propertyToIgnoreC");

I think this is the cleanest way. Remember to check the Javadoc for caveats!
