@JsonManagedReference is the forward part of reference - the one that gets serialized normally. @JsonBackReference is the back part of reference - it will be omitted from serialization.

@rf3123 3 года назад

Put the annotations @JsonManagedReference and @ JsonBackReference above the variable and not the getter/setter.

@cinemaismywife 3 года назад

But what if we are using lombok(@Getter and @Setter) for the entities?

@gsdevman7781 3 года назад

have you found a solution for your problem.?

@cinemaismywife 3 года назад

@@gsdevman7781 Yes, you just need to do as the video says, even though we declare lombok. We can just generate the getter method and use the annotation on that. That the solution.

@blueb00d74 4 года назад

It solves the recursion but I have faced another problem, when i try to insert new data. In my case, I have items and suppliers. Items and supplieres have a @manytomany relationship, I did exactly the same as you and Ii can get the Json perfectly, but when I try to insert a new item I have a deserialization problem. The message which I got is: 2019-11-16 16:48:00.072 WARN 824 --- [nio-8180-exec-2] .c.j.MappingJackson2HttpMessageConverter : Failed to evaluate Jackson deserialization for type [[simple type, class com.company.api.model.Item]]: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot handle managed/back reference 'defaultReference': back reference type (java.util.List) not compatible with managed type (com.ikea.api.model.Item)

@KindsonTheTechPro 4 года назад

You need to cross-check your code. However, alternatively, you can try the JsonIdentityInfo() annotation to see if the problem is solved.

@sanjeewanayanananda9657 4 года назад

If you have more than one @JsonBackReference annotation in your model, then you need to specify a value for that explicitly. check this link here if you are still having the problem. stackoverflow.com/questions/20119142/jackson-multiple-back-reference-properties-with-name-defaultreference

@Gorky25 3 года назад

How does this infitive loop happen? That is mean every time when we have OneToMany and ManyToOne relationship we have to have @JsonManageReference and @JsonBackReference ?
