`java.io.StreamCorruptedException：块data`意外结束从文件

Question

读取某些对象时，我有一些非常基本的序列化代码：

void serializeObjectToFile(Serializable serializable, File file) { 
    ObjectOutputStream stream = null; 
    try { 
     stream = new ObjectOutputStream(new FileOutputStream(file)); 
     stream.writeObject(serializable); 
     stream.flush(); 
    } catch (Exception exception) { 
     logger.error("Failed to serialize object: {}.", serializable, exception); 
    } finally { 
     if (stream != null) { 
      try { 
       stream.close(); 
      } catch (IOException exc) { 
       logger.error("Error closing stream.", exc); 
      } 
     } 
    } 
} 

而且还有一些很反串行化代码：

Object deserializeObjectFromFile(File file) { 
    ObjectInputStream oiStream = null; 
    try { 
     oiStream = new ObjectInputStream(new FileInputStream(file)); 
     return oiStream.readObject(); 
    } catch (Exception exc) { 
     logger.error("Exception loading object from file '{}'.", file.getAbsolutePath(), exc); 
    } finally { 
     if (oiStream != null) { 
      try { 
       oiStream.close(); 
      } catch (IOException exc) { 
       logger.error("Error closing stream.", exc); 
      } 
     } 
    } 
    return null; 
} 

此代码适用于大多数对象。但是，对于某些对象，我得到以下异常：

我不尝试序列每个文件的多个对象（通过对主题的其他问题的建议）。该代码适用于大多数对象，但不适用于某些对象。由于ArrayList.readObject()出现在堆栈跟踪中：这是否与问题有关？如果是这样，什么？令我惊讶和失望的是，我没有在网络上发现有关这个问题的任何信息......

我很欣赏任何关于从哪里出发的指针......！

我发现这个问题：一个对象的对象图中的深跌中实现以下方法：

private void writeObject(java.io.ObjectOutputStream out) throws IOException 

没有实际写入其内部的ObjectOutputStream并没有抛出异常（该方法用于实施验证目的）。所以解决方案：在实现这种方法时，抛出某种类型的Exception或将对象的内部写入ObjectOutputStream。最简单的就是叫

out.defaultWriteObject();
