从套接字读取/解密时的java.io.EOFException

我有一个大型客户机-服务器程序

但是，如果我发送一个加密包，在尝试接收和解密它时，会导致java.io.EOFException

例如，如果我使用非加密的方式进行ping，它将非常有效

客户端代码接收：

服务器代码发送：

java:104是这一行Response res=Response ois.readObject

不能在同一套接字上混合使用不同的缓冲流。他们会互相窃取数据。在套接字的生命周期中，您需要使用单个ObjectInputStream和ObjectOutputStream重新设计和重写它

---

可能您正在查找SealeObject？

这与您的问题无关，但您应该正确使用IV：加密时将其设置为不可预测的随机值，以不需要加密的方式传输，解密时使用它。按你的身份使用静脉注射是不安全的。我知道。这只是为了测试。因为如果它始终是0000000，我不需要发送它，我会尝试将两种不同类型的流分开：编写一个简单的方法来解密加密流，并首先处理几个字节以确保其正常工作，然后再尝试通过发送序列化对象。只有我的2美分。密封对象-密封交易，非常有用。如果这是1，我就是古玩。以及如何绕过这一点。假设我想使用GZip解压/压缩->加密/解密->对象入/出流，我该怎么做呢。它们都是缓冲的，但从功能上讲是有意义的。你可以参考一篇文章/博客来进一步解释这一点吗
