1 ObjectMapper objectMapper = new ObjectMapper();
2 String jsonStr = objectMapper.writeValueAsString(dataDTO);

反序列化：

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);
