In this test code, we define a POJO class called MessageData, which you can find at the link below.

https://github.com/cwiki-us-demo/serialize-deserialize-demo-java/blob/master/src/main/java/com/insight/demo/serialize/model/msgpack/MessageData.java

Serialization and deserialization of POJO

You simply instantiate MessagePackFactory and pass parameters to the constructor of com.fasterxml.jackson.databind.ObjectMapper.

You can then format the data using Message Pack in the same way as jackson-databind.

This test method can be found at https://github.com/cwiki-us-demo/serialize-deserialize-demo-java/blob/master/src/test/java/com/insight/demo/serialize/MessagePackSerializer.java
