Stop manually mapping your DTOs
In service development, DTOs play a crucial role in decoupling consumers. Let’s explore the alternatives we have for effectively translating our core business entities to DTOs and vice versa.
Introduction
Data Transfer Object (DTO)
Data Transfer Object is one of the most common concepts in terms of Architecture when returning data structures in our services. Many services return business objects or graphs with related business objects. That is, when we have a method that returns information about People, the simplest approach is to return, for example, a list of People from a service.
Why do we need a mapping framework ?
In Java applications, it’s common to utilize various data structures tailored for different purposes. For instance, you might employ an object model to represent entities within your domain, such as customers, orders, or products. Simultaneously, you may require interaction with a distinct set of data structures like data transfer objects (DTOs), facilitating data transfer across diverse layers of your application or interfacing with external systems.
