@Deprecated @Sharable public class ObjectEncoder extends MessageToByteEncoder<java.io.Serializable>
Deprecated.This class has been deprecated with no replacement, because serialization can be a security liabilityAn encoder which serializes a Java object into aByteBuf
.Please note that the serialized form this encoder produces is not compatible with the standard
ObjectInputStream
. Please useObjectDecoder
orObjectDecoderInputStream
to ensure the interoperability with this encoder.Security: serialization can be a security liability, and should not be used without defining a list of classes that are allowed to be desirialized. Such a list can be specified with the jdk.serialFilter system property, for instance. See the serialization filtering article for more information.
