对象序列化工具类

这个类中提供了对象序列化与反序列化的方法，在实际的项目中会经常被用到。

import java.io.*;

public class SerializationUtils {

    //把一个对象序列化
    public static byte[] serialize(Object state) {
        ObjectOutputStream oos = null;
        try {
            ByteArrayOutputStream bos = new ByteArrayOutputStream(512);
            oos = new ObjectOutputStream(bos);
            oos.writeObject(state);
            oos.flush();
            return bos.toByteArray();
        }
        catch (IOException e) {
            throw new IllegalArgumentException(e);
        }
        finally {
            if (oos != null) {
                try {
                    oos.close();
                }
                catch (IOException e) {
                    // eat it
                }
            }
        }
    }

    //把一个对象反序列化
    public static <T> T deserialize(byte[] byteArray) {
        ObjectInputStream oip = null;
        try {
            oip = new ObjectInputStream(new ByteArrayInputStream(byteArray));
            @SuppressWarnings("unchecked")
            T result = (T) oip.readObject();
            return result;
        }
        catch (IOException e) {
            throw new IllegalArgumentException(e);
        }
        catch (ClassNotFoundException e) {
            throw new IllegalArgumentException(e);
        }
        finally {
            if (oip != null) {
                try {
                    oip.close();
                }
                catch (IOException e) {
                    // eat it
                }
            }
        }
    }
