我想序列化和反序列化Apache、okhttp客户端等的http响应对象。
我无法使用-〉

1. JavaSerializable作为响应对象的两个客户端都不实现可串行化接口。
   1.Jackson因为响应对象没有无参数构造函数，因此在反序列化时显示以下错误。

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `org.example.Student` (no Creators, like default constructor, exist): cannot deserialize from Object value (no delegate- or property-based Creator)

1.Gson由于内存不足错误：
（下面使用ApacheClient）

序列化：

Gson gson = new GsonBuilder().setPrettyPrinting().create();
       ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
       OutputStreamWriter writer = new OutputStreamWriter(outputStream);
       gson.toJson(httpResponse, writer);
       writer.flush();

反序列化：

byte[] data = outputStream.toByteArray();
       ByteArrayInputStream inputStream = new ByteArrayInputStream(data);
       InputStreamReader reader = new InputStreamReader(inputStream);
       HttpResponse res = gson.fromJson(reader, HttpResponse.class);
       System.out.println("HttpResponse-> " + EntityUtils.toString(res.getEntity()));

错误：
