提示反序列化的时候有问题

spring boot 在分离依赖jar，配置文件时，生产也会报这个错

我解决了，分离打包的时候，这个错误是由于分离打包-序列化时使用的 ClassLoader不同导致找不到class，出现的现象就是在IDEA能正常运行，打包之后就会报there is not session的错误，解决的方法是在maven打包插件那里加<classifier>exec</classifier>，我是看了这个博客才知道的，https://www.cnblogs.com/chen-lhx/p/7778111.html

或者参考https://www.jianshu.com/p/32d38a7fd20a 用JdkSerializationRedisSerializer，这个我试了，也可以

这个问题我在序列化时也遇到了，3.2.3版本，请问怎样解决？或者哪个版本没有这个问题？ public byte[] serialize(Object object) throws SerializationException { byte[] result = new byte[0]; if (object == null) { return result; } else { ByteArrayOutputStream byteStream = new ByteArrayOutputStream(128); if (!(object instanceof Serializable)) { throw new SerializationException("requires a Serializable payload but received an object of type [" + object.getClass().getName() + "]"); } else { try { ObjectOutputStream objectOutputStream = new ObjectOutputStream(byteStream); objectOutputStream.writeObject(object); // 这里报错了 objectOutputStream.flush(); result = byteStream.toByteArray(); return result; } catch (IOException var5) { throw new SerializationException("serialize error, object=" + object, var5); } } } }
