ConcurrentLinkedQueue: NotSerializableException

Question

我需要序列化ConcurrentLinkedQueue。

public class Service implements Serializable { 
    private static Queue<Message> messages = new ConcurrentLinkedQueue<>(); 

    public class Serialize {
        public static Queue<Message> getMessages() 
        { 
            return messages; 
        } 
    }
}

试着：

FileOutputStream fos = new FileOutputStream("filename");
ObjectOutputStream oos = new ObjectOutputStream(fos);

oos.writeObject(Service.Serialize.getMessages());

结果：

java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1184) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1548) at java.io.ObjectOutputStream.defaultWriteObject(ObjectOutputStream.java:441) at java.util.concurrent.ConcurrentSkipListMap.writeObject(ConcurrentSkipListMap.java:1430) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at java.io.ObjectStreamClass.invokeWriteObject(ObjectStreamClass.java:988) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1496) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1432) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1178) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1548)在java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1509) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1432) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1178) at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:348)

如何？

Answer 1

在这个类中的某个地方，您忽略了发布，您正在使用并试图序列化一个匿名内部类，这显然是异常声明的。

Answer 2

也许您应该摆脱内部类序列化，并将方法放在服务中。
