JPA: Having lists on both ends without infinite loop

问题

I am trying to link two entities via Set properties like:

Entity A:

Set<Group> groups

Entity B:

Set<Filter> filters

However, I keep getting errors like infinite recursions. What is the best way to do this with JPA?

回答1:

It goes into infinite recursion because both your entities call each other and it will never stop. Try adding

@JsonManagedReference(value = "group-filter")
Set<Group> groups

and

@JsonBackReference(value = "user-card")
Set<Filter> filters

above both the sets in your entities. It is used to warn spring not go into infinite recursion.
