将JSON反序列化为ArrayList 使用杰克逊

您可以使用

TypeReference

public static <T> T fromJSON(final TypeReference<T> type,      final String jsonPacket) {   T data = null;   try {      data = new ObjectMapper().readValue(jsonPacket, type);   } catch (Exception e) {      // Handle the problem   }   return data;}

并且用于：

final String json = "";Set<POJO> properties = fromJSON(new TypeReference<Set<POJO>>() {}, json);
