Jackson deserialization max depth level
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
With Spring Boot application I post JSON with 10000 nested elements, like the one below and got java.lang.StackOverflowError.
{
"__id": "1",
"__category":{
"key1": {
"key2": {
"key3": {
...
...
"key10000": "value"
...
...
}
}
}
}
}
Is there any way to make this error more manageable?
I mean, I don't want avoid this error, but do something like custom deserializer to set a value of nesting allowed and throw some exception if this value exceeded.

You could try using the Jackson Streaming API instead of having to deserialize the whole thing at once. That's the recommended approach when dealing with a large JSON object or array.
This allows you to deserialize and process components individually without needing the entire JSON object to exist in memory.

As I understand, the main point of my problem is a big number of recursive calls. I catchjava.lang.StackOverflowErrorduring recursive call ofcom.fasterxml.jackson.databind.deser.std.BaseNodeDeserializer.deserializeObject()method. So if I use Jackson Streaming API, I will catch the same error because of very big depth of my JSON's nesting.

@Andrew With the streaming API you should be able to work with iteration instead of recursion which should substantially reduce the memory footprint. You might need a state machine if the input is fairly complex.
