I am creating a project with ArangoDb for my research. It is a backend project with Spring boot. I was following the tutorials here:
https://github.com/arangodb/spring-data-demo
Everything went well but when I tried creating a controller with the "Character" class. I get this error:
java.lang.StackOverflowError: null
Upon further inspection, I found out that it is the mapping of children and parents that's creating this problem. In a separate project, I created a basic POJO (class Parts) with basic properties such as name, id and a collection of childParts similar to "childs" in your character class. I did all the mappings (with edges and all) and created the relationships. Then if I have two Parts Objects, P1 and P2, and I make P2 childPart of P1. The JSON response comes as P2 as child of P1 and then P1 as child of P2 and again P2 as child of P1 on and on. Its an infinite loop. Earlier I thought there was some problem with my implementation but when I downloaded the demo code. It has the same problem. Please let me know if there is a way to get around this or if I missed something.
The postman response of the tutorial code is actually an infinite loop. Something like this:
[
{
"id": "424543",
"name": "Sansa",
"surname": "Stark",
"alive": true,
"age": 13,
"childs": [
{
"id": "424594",
"name": "Ned",
"surname": "Stark",
"alive": false,
"age": 41,
"childs": [
{
"id": "424606",
"name": "Robb",
"surname": "Stark",
"alive": false,
"age": null,
"childs": [
{
"id": "424594",
"name": "Ned",
"surname": "Stark",
"alive": false,
"age": 41,
"childs": [
{
"id": "424606",
"name": "Robb",
"surname": "Stark",
"alive": false,
"age": null,
"childs": [
{
"id": "424594",
"name": "Ned",
"surname": "Stark",
"alive": false,
"age": 41,
"childs": [
{
