反序列化字符串缓冲区

我有一个 db varchar 字段，看起来像 Java StringBuffer 序列化的结果：

íjava.lang.StringBuffer [many random characters here removed for this question]

如何将其反序列化为 String？

how do I deserialize it into String?

本质上，您需要这样做：

byte[] varcharContents = ... // get the bytes of the field, not via a String
ObjectInputStream ois = 
    new ObjectInputStream(new ByteArrayInputStream(varcharContents));
StringBuffer sb = (StringBuffer)ois.readObject();
String s = sb.toString();

您必须希望能够真正获取序列化生成的原始字节，并且它们在进出数据库的过程中没有被转换。

Essentially you need to do this:

byte[] varcharContents = ... // get the bytes of the field, not via a String
ObjectInputStream ois = 
    new ObjectInputStream(new ByteArrayInputStream(varcharContents));
StringBuffer sb = (StringBuffer)ois.readObject();
String s = sb.toString();

You'll have to hope that you can really get the original bytes produced by the serialisation back, and that they haven't been transformed on their way to and from the DB.
