# Introduction
This project provides a [Serializer](https://kafka.apache.org/0110/javadoc/org/apache/kafka/common/serialization/Serializer.html),
[Deserializer](https://kafka.apache.org/0110/javadoc/org/apache/kafka/common/serialization/Deserializer.html) and a
[Serde](https://kafka.apache.org/0110/javadoc/index.html?org/apache/kafka/common/serialization/Serde.html) for
Kafka Streams using [Jackson](https://github.com/FasterXML/jackson) for JSON processing. All of the
available settings for Jackson are configurable.
[](https://www.mvnrepository.com/artifact/com.github.jcustenborder.kafka/kafka-jackson)
# What if I don't know what settings to use.
If you are already defining a ObjectMapper that works for you and you want to use it's settings. Use
this method to dump the non default settings. This will compare all of the default settings against
the supplied ObjectMapper and return the configuration values that the equivalent.
```java
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.configure(SerializationFeature.INDENT_OUTPUT, true)
Map actual = JacksonSerializer.nonDefaultSettings(objectMapper);
```
# Kafka Streams Serde
The Serde can be configured by passing in the class to deserialize to. This will return a Serde with
configured to the object type. When configure is called it will ignore any `output.class` supplied
since it has already been configured.
```java
Serde serde = JacksonSerde.of(TestPojo.class);
```
# Serializer
The Serializer does not need to be specified with a type. It will serialize any object that is passed to it.
```java
Map settings = ImmutableMap.of(
ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, JacksonSerializer.class.getName(),
ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, JacksonSerializer.class.getName()
);
Producer producer = new KafkaProducer<>(settings);
// Do your thing
```

# Deserializer
## Generically processing Json
By default if you do not configure a class to deserialize to the serializer will deserialize to a Jackson
JsonNode. Assuming that your data is Json objects you can use ObjectNode.
```java
Map settings = ImmutableMap.of(
ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, JacksonDeserializer.class.getName(),
ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, JacksonDeserializer.class.getName()
);
Consumer consumer = new KafkaConsumer(settings);
// Do your thing
```
## Strongly typed Json
You can tell the deserializer to deserialize to a Pojo.
```java
Map settings = ImmutableMap.of(
ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, JacksonDeserializer.class.getName(),
ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, JacksonDeserializer.class.getName(),
"value.deserializer.output.class", TestPojo.class.getName()
);
Consumer consumer = new KafkaConsumer<>(settings);
```
