Mano, tu é um gênio!!! Estou há 2h pensando como eu poderia associar um @ManyToMany no JSON já que eu sabia que os meus dois Entity estavam funcionando como esperado. Agora, terei que ver como esse código funciona para futuras apliações.

JsonIgnore stops the circular but also stops adding employee to Project, so just makes it a more complex one to many.

[@johnvick8861]

Use @jsonbackreferrence on top of get method

I love you smart Indian wizard!
This helped a lot.
I do have one question though: is there a way to create an Employee with a Post method that also takes in input a set of Projects?
Ill' try to explain it better. In the video you create an Employee, you create a Project and then you add the projects to the employee one by one. I'm looking for a way to add multiple projects to the employee when I'm creating the employee. So in your example when creating the employee I would like to pass a name (employee name) and a set that contains multiple projects.

[@dev2prodcoding]

Thanks...Glad that you liked it.
Is there a way to create an Employee with a Post method that also takes in input a set of Projects? -> Yes, it can be done. You can use one-to-many mapping to add multiple projects to the employee. You can check czcams.com/video/2fvUrpYG95w/video.html for more on this.

Finally i have found.....What i excellently want.

[@massimoramaj3233]

Is there any specific reason why you did not use @Getter and @Setter in employee entity?

[@antoninodelfiume5932]

why i'm getting, forbidden?

[@medyazidhamlaoui2703]

Thank you, what i do whene i want to assign project to Employee ?

[@TheKnightKing007]

if u want assign one project to one person means go for @OneToOne,
if multiple project to one person mean go for @OneToMany,
if one project involved to many persons means @ManyToOne
if Many person collap with many project means go for @ManyToMany

[@gajanangaikwad8934]

To delete a Project , we need to go throw every employee and remove the project form him to perform our task?

[@AshuKumar-kw8bi]

bhai tera project kisi kam ka nhi hai...tum ache ache comment khud hi fake account se karte ho kya

[@nishantsingh4366]

From where you got getAssignedProjects()in service

[@dev2prodcoding]

Please check Employee entity class, there I have defined
private Set assignedProjects = new HashSet();
getAssignedProjects() is the getter method for the same which is auto generated by lombok.Data annotation. Hope it helps!
