Type Handling Annotations in Jackson
Type Handling annotations are used for handling types of properties. Jackson provides more than one Type Handling annotations such as JsonTypeInfo, JsonSubTypes, and JsonTypeName. Type Handling annotation can be used at the time of serializing an object or deserializing a Json string.
Let's understand each one of them one by one with an example to understand how these annotations are used for type handling.
It is one of the most used Type Handling annotations which we used at the time of serializing an object. It is used for indicating the details of what type of information to include in serialization and deserialization.
Let's take an example to understand how the annotation is used for getting the detail of information.
It is another most used THandling annotation, which we also used at the time of serializing and deserializing an object. It is used for indicating subtypes of types annotated. The @JsonSubTypes annotation is used with @JsonTypeInfo annotation.
Let's take an example to understand the use of annotation.
It is another important Type Handling annotation, i.e., used for setting types name to be used for annotated class.
Let's take an example to understand how the annotation works in Java:
