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。
我们需要先定义一个对象的 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(); } }
