我創(chuàng)建了一個(gè)名為Components. 它有一些組件，如Button, TextArea,VerticalLayout等。我沒有使這個(gè)類可序列化，因?yàn)槲也恍枰?，但是?dāng)我啟動(dòng)服務(wù)器時(shí)（我使用 Tomcat），我得到這個(gè)錯(cuò)誤：java.io.NotSerializableException: com.vaadin13.Components at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1184) at java.io.ObjectOutputStream.writeArray(ObjectOutputStream.java:1378) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1174) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1548) at 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.defaultWriteFields(ObjectOutputStream.java:1548) at 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.writeArray(ObjectOutputStream.java:1378) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1174) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1548) at 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.defaultWriteFields(ObjectOutputStream.java:1548) at 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)...當(dāng)我的類不可序列化時(shí)，為什么會(huì)出現(xiàn)此錯(cuò)誤，我該如何解決？

要修復(fù)此錯(cuò)誤，請(qǐng)實(shí)現(xiàn) Serializable 接口并為其指定一個(gè) id。
Public class Foo implements Serializable {
private static final long serialversionUID = 1L; // example
//code then
}
