In the last year i have switches to .net core and c# environment due to my work. This is why i didnt upload any more courses, if you expect more spring/java related content then you don't have to subscribe. If you are interested in .net world make sure to subscribe because courses are coming!!!!

Thank you for sharing all the relationship using dto structure and one thing is that you include very long way of converting object to Dto . Apart from that you have to use MODELMAPPER CLASS so this will reduce the code of converting regular object to Dto object.

Your work is excellent. But I have a question. When you retrieve data, do you meet the problem that there are many repeated data on one to many or many to many relationships. I'm doing my project and meet that product A have category 1, product B have category 1 and when I retrieve product, it returns product a - category 1 [product A B], product B -category 1 [product A B]. Can you help me to this issue.
