如何把一个对象序列化存入数据库–备忘系列

用函数 serializeObject 把对象序列化成byte型数组，然后以byte数组形式存入数据库。读的时候也就是其逆过程，用ObjectInputStream 读入一个对象即可，如下unSerializeObject函数。

public byte[] serializeObject(Object pObject) throws Exception {
byte[] returnValue = null;

ByteArrayOutputStream byteStream = new ByteArrayOutputStream(5000);
ObjectOutputStream os = new ObjectOutputStream(
new BufferedOutputStream(byteStream));
os.flush();
os.writeObject(pObject);
os.flush();
//retrieves byte array
returnValue = byteStream.toByteArray();

os.close();
os = null;

return (returnValue);

} // ***End public byte[] serializeObject (Object pObject)

public Object unSerializeObject(byte[] pBytes) throws Exception {
Object returnValue = null;

ByteArrayInputStream byteStream = new ByteArrayInputStream(pBytes);
ObjectInputStream is = new ObjectInputStream(new BufferedInputStream(
byteStream));
returnValue = is.readObject();
is.close();

return (returnValue);

} // ***End public Object unSerializeObject (byte[] pBytes )
