Hello, dear readers! Those who develop Web applications in Java using the Spring framework, those who comment on these applications and are simply interested.
 
In the previous article 3-333231. "Spring Boot Solving a Problem with ManyToMany"
 
I gave an example of a test application executed, in which there is a bidirectional relation between ManyToMany between the two classes. The article gave an example of solving a looping problem when receiving a rest response using the DTO class. Readers in the comments suggested using the 3r313 library to solve the looping problem. MapStruct
 
After reading 3r317. 3r3236. I made sure that this is a really strong thing, with the help of which you can solve quite complex tasks of moving data between objects. MapStruct solves the problem of looping including.
 
In this article, I will give an example of solving the same problem as a Spring Boot application using the MapStruct library. Source code Available on Github
