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

在本測試代碼中，咱們定義了一個 POJO 類，名字爲 MessageData，你能夠訪問下面的連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

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

咱們須要先定義一個對象的 List 列表。

/**
 * SerializationList
 */
@Test
public void testMessagePackSerializationList() {

    byte[] bytes = new byte[0];
    String uuid = UUID.randomUUID().toString();

    // Instantiate ObjectMapper for MessagePack
    ObjectMapper objectMapper = new ObjectMapper(new MessagePackFactory());

    List<MessageData> objList = MockDataUtils.getMessageDataList(9);

    try {
        // Serialize a Java object to byte array
        bytes = objectMapper.writeValueAsBytes(objList);
        logger.debug("Length of Bytes: [{}]", bytes.length);

        // Deserialize the byte array to a Java object
        // Deserialize the byte array to a List
        List<MessageData> deserialized = objectMapper.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();
    }

}
