一、处理流
二、缓冲流
三个类经常用于处理数据流：
三、序列化工具：
public class SerializeUtil {
/**
* 序列化
*
* @param object
* @return
*/
public static String serialize(Object object) {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream oos = null;
try {
oos = new ObjectOutputStream(bos);
oos.writeObject(object);
oos.flush();
return new BASE64Encoder().encode(bos.toByteArray());
} catch (IOException e) {
System.out.println("序列化错误");
e.printStackTrace();
} finally {
try {
if (oos != null) {
oos.close();
}
bos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return null;
}
/**
* 反序列化
*
* @param object
* @return
*/
public static Object unserialize(String object) {
ByteArrayInputStream bis = null;
ObjectInputStream ois = null;
try {
bis = new ByteArrayInputStream(new BASE64Decoder().decodeBuffer(object));
ois = new ObjectInputStream(bis);
Object o = ois.readObject();
return o;
} catch (IOException e) {
System.out.println("反序列化错误:IO异常");
e.printStackTrace();
} catch (ClassNotFoundException e) {
System.out.println("反序列化错误:类找不到");
e.printStackTrace();
} finally {
try {
if (bis != null) {
bis.close();
}
if (ois != null) {
ois.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
return null;
}
}
