Class JsonDeserializer<T>

java.lang.Object
org.springframework.kafka.support.serializer.JsonDeserializer<T>
Type Parameters:
T - class of the entity, representing messages
All Implemented Interfaces:
Closeable, AutoCloseable, org.apache.kafka.common.serialization.Deserializer<T>
@Deprecated(forRemoval=true, since="4.0") public class JsonDeserializer<T> extends Object implements org.apache.kafka.common.serialization.Deserializer<T>
Deprecated, for removal: This API element is subject to removal in a future version.
since 4.0 in favor of JacksonJsonDeserializer for Jackson 3.
Generic Deserializer for receiving JSON from Kafka and return Java objects.

IMPORTANT: Configuration must be done completely with property setters or via configure(Map, boolean), not a mixture. If any setters have been called, configure(Map, boolean) will be a no-op.
