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

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。

我们需要定义测试需要的 MAP，定义 Map 的方法你可以在下面的测试程序中找到。

/**

  * SerializationMap

  */

 @Test

 public void testMessagePackSerializationMap() {

     byte[] bytes = new byte[0];

     String uuid_a = UUID.randomUUID().toString();

     String uuid_b = UUID.randomUUID().toString();

     // Instantiate ObjectMapper for MessagePack

     ObjectMapper objectMapper = new ObjectMapper(new MessagePackFactory());

     Map<String, MessageData> map = new HashMap<>();

     MessageData messageData = new MessageData();

     // Element A in MAP

     messageData.setUuid(UUID.randomUUID().toString());

     messageData.setName("CWIKI.US - A");

     map.put(uuid_a, messageData);

     // Element B in MAP

     messageData = new MessageData();

     messageData.setUuid(UUID.randomUUID().toString());

     messageData.setName("CWIKI.US - B");

     map.put(uuid_b, messageData);

     try {

         // Serialize a Java object to byte array

         bytes = objectMapper.writeValueAsBytes(map);

         logger.debug("Length of Bytes: [{}]", bytes.length);

         // Deserialize the byte array to a MAP

         Map<String, MessageData> deserialized = objectMapper.readValue(bytes, new TypeReference<Map<String, MessageData>>() {

         });

         logger.debug("Deserialized MAP Count: [{}]", deserialized.size());

         logger.debug("MAP index 0: [{}]", deserialized.get(uuid_a).getName());

         assertEquals("CWIKI.US - A", deserialized.get(uuid_a).getName());

     } catch (JsonProcessingException ex) {

         logger.error("Serialize Error", ex);

     } catch (IOException e) {

         e.printStackTrace();

     }

 }
