Modify object serialization depending on what class is being serialized

Question

So my goal is to return some objects as the response body from a Spring REST controller. The thing is, these two objects point each other, something kind of like this:

public class Person {
    private Set<Team> teams;
}

public class Team {
    private Set<Person> members;
}

If I return these two objects from a controllers mapping method right away, the generated response will be infinite and will probably crash the browser, because the members set has people, and each person has a set of teams, and so on, and everything gets returned infinitely.

How can I manage, instead of showing the whole list of, say, members, to display just the name of each of the members?

Any help will be much appreciated, thanks!

If you are using jackson then you must use jackson provided solution to problem you are mentioning.

@JsonManagedReference

Thanks! The biggest issue here is I did not know how to look it up exactly... Infinite recursion, that was the key! Thanks again – Unai P. Mendizabal Nov 21 '16 at 14:59
