序列化反序列化

序列化：

对象转json 

 1 ObjectMapper objectMapper = new ObjectMapper();

2 String jsonStr = objectMapper.writeValueAsString(dataDTO); 

反序列化：

json转列表

 1 ObjectMapper objectMapper = new ObjectMapper();

2 objectMapper.readValue(jsonStr, new TypeReference<List<FundStatsPeriodConfig>>() {}); 

json转对象

 1 ObjectMapper objectMapper = new ObjectMapper();

2 DataDTO dataDTO = objectMapper.readValue(jsonStr, DataDTO.class);
