Jackson 字符串轉List

String a = "[{\"id\":27,\"text\":\"網絡\"},{\"id\":32,\"text\":\"機身內存\"}]";
ObjectMapper objectMapper = new ObjectMapper();
CollectionLikeType type = objectMapper.getTypeFactory().constructCollectionLikeType(List.class, Map.class);
List<Map> listMap = objectMapper.readValue(a, type);

　　

ObjectMapper objectMapper = new ObjectMapper();
CollectionLikeType type = objectMapper.getTypeFactory().constructCollectionLikeType(List.class, Map.class);
List<Map> listMap = objectMapper.readValue(typeTemplate.getSpecIds(), type);
