MessagePack Java Jackson Dataformat - 列表（List）的序列化和反序列化

在本测试代码中，我们定义了一个 POJO 类，名字为 MessageData，你可以访问下面的链接找到有关这个类的定义。

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

本测试方法，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。

我们需要先定义一个对象的 List 列表。

/** * SerializationList */@Testpublic void testMessagePackSerializationList() {    byte[] bytes = new byte[0];    String uuid = UUID.randomUUID().toString();    // Instantiate  Mapper for MessagePack     Mapper  Mapper = new  Mapper(new MessagePackFactory());    List<MessageData> objList = MockDataUtils.getMessageDataList(9);    try {        // Serialize a Java   to byte array        bytes =  Mapper.writeValueAsBytes(objList);        logger.debug("Length of Bytes: [{}]", bytes.length);        // Deserialize the byte array to a Java          // Deserialize the byte array to a List        List<MessageData> deserialized =  Mapper.readValue(bytes, new TypeReference<List<MessageData>>() {        });        logger.debug("Deserialized List Count: [{}]", deserialized.size());        logger.debug("List index 0: [{}]", deserialized.get(0).name);    } catch (JsonProcessingException ex) {        logger.error("Serialize Error", ex);    } catch (IOException e) {        e.printStackTrace();    }}
