Entity To DTO Conversion using ModelMapper in Spring Boot Application

In this tutorial, we'll handle the conversions that need to happen between the internal entities of a Spring boot application and the external DTOs (Data Transfer Objects) that are published back to the client.

We gonna use the ModelMapper library to convert Entity to DTO and vice versa.

One thing I dont understand the comment class is the same as comment DTO and the post class is the same as the Post DTO, why do you need DTO in these two cases?

Another stupid framework that introduces more magic into your project. THis stuff works as long as you use very simple objects. if there is anything with a hint of more complexity (like transfering a string from a child object of one object, and put it into an array of the other object) everything becomes a hundret times more complicated with this magic stuff, than just writing the conversion by hand.
