java.io.StreamCorruptedException：读取多个对象时格式错误（objectinputstream读取多个对象）

我试图OneChatMessage在每次单击按钮时将对象（类）添加到文件中。然后，我尝试从文件中读取所有对象，并将其加载到ArrayList。但是我在反序列化函数StreamCorruptedException的第二次迭代中得到了一个ObjectInputStream.readObject()。我已经验证了第一次迭代可以正常工作。

我读过许多关于同一问题的其他文章：

1. 一种建议反序列化多个Java对象是将整个数组列表而不是单个对象写入文件。但这似乎很浪费，因为每次单击按钮时我都需要写入文件，并且随着时间的推移将有数百个对象。
2. 另一个建议StreamCorruptedException：无效类型代码：AC与ObjectOutputStream创建的不同标头有关。我不知道该用谁来解决这个问题。

关于如何解决这个问题的任何想法吗？

OneChatMessage.java：

package com.slapp.chat;import java.io.Serializable;import java.util.Date;import com.slapp.localDB.Contact;//This class defines the class for a chat messagepublic class OneChatMessage implements Serializable{    private String text;    private Date timeSent;    private Boolean sentByMe;    public OneChatMessage(String text, Date timeSent, Boolean sentByMe){        this.text = text;        this.timeSent = timeSent;        this.sentByMe = sentByMe;    }    public String getText(){        return this.text;    }    public Date getTimeSent(){        return this.timeSent;    }    @Override    public String toString(){        return new StringBuffer(" Text : ")        .append(this.text)        .append(" TimeSent : ")        .append(this.timeSent.toString()) // Need to use SimpleDatFormat to get the correct time zone and formatting. Leaving it for now.        .append(" SentByMe : ")        .append(this.sentByMe.toString()).toString();    }}

序列化功能：

public void addMessage(OneChatMessage msg) {        FileOutputStream fos;        ObjectOutputStream oos;        File file = new File(context.getFilesDir(), "abc");        if (!file.exists()) {            Log.d("faizal",                    "The file does not exist : ");        } else {            Log.d("faizal",                    "The file already exists : ");        }        try {            fos = context.openFileOutput("abc",                    Context.MODE_APPEND);            oos = new ObjectOutputStream(fos);            oos.writeObject(msg);            oos.close();            fos.close();        } catch (FileNotFoundException e) {            Log.d("faizal", "file not found : ");            e.printStackTrace();        } catch (IOException e) {            Log.d("faizal", "Error closing file : ");            e.printStackTrace();        }}

反序列化功能：

public ArrayList<OneChatMessage> getAllChatMessagesArrayList() {        ArrayList<OneChatMessage> chatMessages = new ArrayList<OneChatMessage>();        OneChatMessage oneChatMsg;        FileInputStream fis;        ObjectInputStream ois;        try {            fis = context.openFileInput("abc");            ois = new ObjectInputStream(fis);            //Setting an arbitrarily large number as the limit of the loop iterations            //so that chat message are read from the file till EOF            for (int i = 1; i < 999999999; i++) {                try {                    oneChatMsg = (OneChatMessage) ois.readObject();                } catch (EOFException e) {                    //When EOFException occurs, quit the loop                    break;                }                try{                    chatMessages.add(oneChatMsg);                } catch(Exception e){                    Log.d("faizal","Error adding message to Array List:" + oneChatMsg.getText());                    e.printStackTrace();                }            }            ois.close();            fis.close();            return chatMessages;        } catch (FileNotFoundException e) {            Log.d("faizal", "The file not found : ");            e.printStackTrace();        } catch (IOException e) {            Log.d("faizal", "Error closing file : ");            e.printStackTrace();        } catch (ClassNotFoundException e) {            Log.d("faizal","Error reading object from file : ");            e.printStackTrace();        } catch (UnsupportedOperationException e) {            Log.d("faizal", "Error adding object to array list from file : ");            e.printStackTrace();        }        return null; // in case there was a caught exception    }

答案1

追加到ObjectOutputStream不能立即使用，因为它会创建多个标头，如
StreamCorruptedException中所述：无效类型代码：AC。

有关解决方案，请参见附加到ObjectOutputStream。
