避免Java声音类中的序列化级联？

目前，我正试图通过一个套接字发送一个对象，它是一个“消息”类，它包含一个音频格式和一个混音器，第二个Java应用程序将使用它来配置自己

public class Message implements Serializable {

private static final long serialVersionUID = 1L;

SerializableAudioFormat audioFormat;
Mixer mixer;

public Message(SerializableAudioFormat audioFormat, Mixer mixer) {
    this.audioFormat = audioFormat;
    this.mixer = mixer;
}

public SerializableAudioFormat getAudioFormat() {
    return this.audioFormat;
}

public Mixer getMixer() {
    return this.mixer;
    }

}

我必须序列化AudioFormat，因为默认情况下它不是，所以我创建了可以在构造函数中看到的类“SerializableAudioFormat”。该类的代码如下所示

SerializableAudioFormat类：

public class SerializableAudioFormat implements Serializable {

private static final long serialVersionUID = 1L;

transient AudioFormat format;

public SerializableAudioFormat(AudioFormat format) {
    this.format = format;
}

public AudioFormat getAf() {
    return this.format;
}

private void writeObject(ObjectOutputStream out) throws IOException {
    out.defaultWriteObject();
    out.writeObject(new SerializableEncoding(format.getEncoding()));
    out.writeFloat(format.getSampleRate());
    out.writeInt(format.getSampleSizeInBits());
    out.writeInt(format.getChannels());
    out.writeInt(format.getFrameSize());
    out.writeFloat(format.getFrameRate());
    out.writeBoolean(format.isBigEndian());
}

private void readObject(ObjectInputStream in) throws IOException, ClassNotFoundException {
    in.defaultReadObject();
    format = new AudioFormat(((SerializableEncoding) in.readObject()).getEncoding(), in.readFloat(), in.readInt(),
            in.readInt(), in.readInt(), in.readFloat(), in.readBoolean());
    }

}

public class SerializableEncoding implements Serializable {

    private static final long serialVersionUID = 1L;

    transient Encoding encoding;

    public SerializableEncoding(Encoding encoding) {
        this.encoding = encoding;
    }

    public Encoding getEncoding() {
        return this.encoding;
    }

    private void writeObject(ObjectOutputStream out) throws IOException {
        out.defaultWriteObject();
        out.writeObject(this);
    }

    private void readObject(ObjectInputStream in) throws IOException, ClassNotFoundException {
        in.defaultReadObject();
        encoding = ((SerializableEncoding) in.readObject()).getEncoding();
    }

}

正如您所看到的，编码也必须被序列化，因为同样的原因。这门课是下面的

SerializableEncoding类：

public class SerializableAudioFormat implements Serializable {

private static final long serialVersionUID = 1L;

transient AudioFormat format;

public SerializableAudioFormat(AudioFormat format) {
    this.format = format;
}

public AudioFormat getAf() {
    return this.format;
}

private void writeObject(ObjectOutputStream out) throws IOException {
    out.defaultWriteObject();
    out.writeObject(new SerializableEncoding(format.getEncoding()));
    out.writeFloat(format.getSampleRate());
    out.writeInt(format.getSampleSizeInBits());
    out.writeInt(format.getChannels());
    out.writeInt(format.getFrameSize());
    out.writeFloat(format.getFrameRate());
    out.writeBoolean(format.isBigEndian());
}

private void readObject(ObjectInputStream in) throws IOException, ClassNotFoundException {
    in.defaultReadObject();
    format = new AudioFormat(((SerializableEncoding) in.readObject()).getEncoding(), in.readFloat(), in.readInt(),
            in.readInt(), in.readInt(), in.readFloat(), in.readBoolean());
    }

}

public class SerializableEncoding implements Serializable {

    private static final long serialVersionUID = 1L;

    transient Encoding encoding;

    public SerializableEncoding(Encoding encoding) {
        this.encoding = encoding;
    }

    public Encoding getEncoding() {
        return this.encoding;
    }

    private void writeObject(ObjectOutputStream out) throws IOException {
        out.defaultWriteObject();
        out.writeObject(this);
    }

    private void readObject(ObjectInputStream in) throws IOException, ClassNotFoundException {
        in.defaultReadObject();
        encoding = ((SerializableEncoding) in.readObject()).getEncoding();
    }

}

问题是我一开始就犯了一个错误说

线程“main”java.io.WriteableOrtedException中出现异常：写入中止；java.io.NotSerializableException:

首先使用AudioFormat直到我包装它，然后使用AudioFormat.Encoding直到我也包装它

现在，我的问题是接口混合器，因为我得到的错误消息如下

线程“main”java.io.WriteAbortedException中出现异常：写入中止；java.io.NotSerializableException:com.sun.media.sound.DirectAudioDevice

所以我的问题是，对于这种场景，如果您还没有开发类，并且大多数类都没有实现可序列化，那么还有其他解决方法吗？可以避免这种“大规模序列化”吗？

回答标题中的问题：

out.writeObject(this);

递归就在这里。你已经在打电话了。删除。

感谢您的回复，解决了问题！但是，当一个NullPointerException弹出时，我似乎无法向其他Java应用程序获取该字段的值。是否还有其他与序列化相关的问题？
