MessagePack Java Jackson Dataformat - POJO 的序列化和反序

在本測試代碼中，我們定義了一個 POJO 類，名字為?MessageData，你可以訪問下面的鏈接找到有關這個類的定義。

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

POJO 的序列化和反序列化

你僅僅需要對?MessagePackFactory?進行實例化，然后傳遞參數到?com.fasterxml.jackson.databind.ObjectMapper?的構造方法。

然后你就可以用與?jackson-databind?相同的方法使用?MessagePack?格式化數據。

本測試方法，可以在?https://github.com/cwiki-us-demo/serialize-deserialize-demo-java/blob/master/src/test/java/com/insight/demo/serialize/MessagePackSerializer.java?中找到。
