There are several ways to do it depending on the purpose. Mapstruct - Prepare a list from a group of fields from the source object and set it to target object.

Spring Boot Unit Test ignores logging.level. Ignoring Unmapped Properties with MapStruct MapStruct allows us to copy between Java beans. Third-Party API Integration with Lombok. Based on our declarations, MapStruct will generate the mapping code automatically. IGNORE: no output or errors In order to ignore unmapped properties and get no output warnings, we should assign the IGNORE value to the unmappedTargetPolicy. Additionally, mapper configuration classes may declare one more prototype mapping methods.
