DTO can be also I have just one problem. Here is an example of what I've come up with Alexander Ivanchenko 29. What could be the motives for using DTOs in our applications? How to create them properly? Is Spring Data In this guide, we compare the traditional approach (pre-Java 8) with Stream API approach for converting entities into DTOs and vice versa. In this tutorial, we’ll explain how to map lists of different element types using the ModelMapper framework.
