In the previous articles, we explored techniques for handling unknown fields during serialization. In this article, we’ll shift our focus to exclude known fields during serialization and deserialization by using Jackson annotations.
In this article, we will explore how to handle situations when you’re deserializing JSON data into Java objects using Jackson, and the JSON contains fields that are not present in the Java class.
In the first article of our Jackson tutorial series, we learned how to convert JSON string into Java objects. In this article, we will explore the reverse process – converting Java objects, arrays, and lists into JSON strings using the ObjectMapper class.
Jackson is a widely-used library in the Java ecosystem for working with JSON data. The ObjectMapper class, a core component of Jackson, simplifies the process of converting JSON string to Java objects, object arrays and list of objects.
