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

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。

我們需要定義測試需要的 MAP，定義 Map 的方法你可以在下面的測試程序中找到。

/**
??*?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();
?????}
