The most basic way to persist a JSON object in a relational database is to convert the object into a String before persisting it. Storing highly nested JSON with only one value per map is a pathological case just for testing. Several object-oriented programming languages directly support object serialization (or object archival), either by syntactic sugar elements or providing a standard interface for doing so. com, we won't encourage audio ads, popups or any other annoyances at any point, hope you support us :-) Thank you. A Map, Object array or primitive array parsed from the JSON. In our previous article, we have learned how to use the Jackson API for binding JSON data to Plain Old Java Object (POJO) and vice versa.
