Managing Subclass Serialization with Jackson
When dealing with complex data structures that involves classes and sub-classes in Java that require JSON serialization and deserialization, managing polymorphism can be challenging. Fortunately, the Jackson library provides powerful annotations like @JsonTypeInfo and @JsonSubTypes that simplify this task. Jackson Annotations Jackson’s annotations @JsonTypeInfo and @JsonSubTypes are pivotal for handling polymorphic types. They enable Jackson to serialize subclass types accurately and deserialize JSON back into the correct Java subclasses. @JsonTypeInfo Usage The @JsonTypeInfo annotation helps specify metadata about how subclasses are identified in the JSON output. Key attributes include: ...
