This class has been deprecated with no replacement, because serialization can be a security liability

@Deprecated
public class ObjectDecoder
extends LengthFieldBasedFrameDecoder

A decoder which deserializes the received ByteBufs into Java objects.

Please note that the serialized form this decoder expects is not compatible with the standard ObjectOutputStream. Please use ObjectEncoder or ObjectEncoderOutputStream to ensure the interoperability with this decoder.

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.

ObjectDecoder

public ObjectDecoder(ClassResolver classResolver)

已过时。

Creates a new decoder whose maximum object size is 1048576 bytes. If the size of the received object is greater than 1048576 bytes, a StreamCorruptedException will be raised.

参数:

classResolver - the ClassResolver to use for this decoder

ObjectDecoder

public ObjectDecoder(int maxObjectSize,
                     ClassResolver classResolver)

已过时。

Creates a new decoder with the specified maximum object size.

参数:

maxObjectSize - the maximum byte length of the serialized object. if the length of the received object is greater than this value, StreamCorruptedException will be raised.

classResolver - the ClassResolver which will load the class of the serialized object

decode

protected java.lang.Object decode(ChannelHandlerContext ctx,
                                  ByteBuf in)
                           throws java.lang.Exception

已过时。

从类复制的说明: LengthFieldBasedFrameDecoder

Create a frame out of the ByteBuf and return it.

覆盖:

decode 在类中 LengthFieldBasedFrameDecoder

参数:

ctx - the ChannelHandlerContext which this ByteToMessageDecoder belongs to

in - the ByteBuf from which to read data

返回:

frame the ByteBuf which represent the frame or null if no frame could be created.

抛出:

java.lang.Exception
