Question

I have an object with unknown values, say

{
 "data": [
    {"a":...,
    "dont_know_what_else_is_here":....}
 ]
}

And I just want to store the value of “data” as a string into a variable/database.

How should I read it from the streaming API?

Answer 1

Provided that you have already read this object into JsonNode, you can do it like this:

String content = jsonNode.get("data").textValue();

UPD: since you’re using a streaming parser, this example on Jackson usage might help.

UPD: the method name is now textValue() – docs
