When I am extracting the data using below code-

privateKey = json.get("Key").toString();

I am still getting the escape characters. Is there any other method which I got to use for extracting data from JsonNode.

Answer 1

toString gives a developer friendly string, but if you want the actual contents from a string node, you probably want textValue().

public abstract String toString()
Method that will produce developer-readable representation of the node; which may or may not be as valid JSON. If you want valid JSON output (or output formatted using one of other Jackson supported data formats) make sure to use ObjectMapper or ObjectWriter to serialize an instance, for example:

public String textValue()
Method to use for accessing String values. Does NOT do any conversions for non-String value nodes; for non-String values (ones for which isTextual() returns false) null will be returned. For String values, null is never returned (but empty Strings may be)
