java 游戏高级编程中 的对象串行化 存取

数据存取，没想象中的那么复杂，java中已经有很好的方法。转自《java游戏高级编程》 清华大学出版社

package tools;import java.io.BufferedInputStream;import java.io.BufferedOutputStream;import java.io.ByteArrayOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.ObjectInputStream;import java.io.ObjectOutputStream;import java.io.OutputStream;import java.io.Serializable;import java.util.zip.GZIPInputStream;import java.util.zip.GZIPOutputStream;/** *  * @author ttwings * @version 0.1 * @since 2015-10-19 上午9:04:50 *  */public class SerializableLib {public static byte[] compress(Serializable serializable) throws IOException{ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();save(serializable ,byteArrayOutputStream);return byteArrayOutputStream.toByteArray();}/** * 保存数据 * @param serializable * @param outputStream * @throws IOException */public static void save(Serializable serializable,OutputStream outputStream) throws IOException{ObjectOutputStream objectOutputStream = null;try{objectOutputStream = new ObjectOutputStream(new GZIPOutputStream(new BufferedOutputStream(outputStream)));}finally{if(objectOutputStream != null){objectOutputStream.close();}else{outputStream.close();}}}/** * 读取数据 * @param inputStream 输入数据流 * @return * @throws ClassNotFoundException * @throws IOException */public static Serializable load(InputStream inputStream) throws ClassNotFoundException,IOException{ObjectInputStream objectInputStream = null;try{objectInputStream= new ObjectInputStream(new GZIPInputStream(new BufferedInputStream(inputStream)));return (Serializable) objectInputStream.readObject();}finally{if(objectInputStream != null){objectInputStream.close();}else{inputStream.close();}}}}

ps：做了初步测试，完全可以用。200 M 多的地图数据，直接压缩成 2M 大小的文件。。 = = 。
