Java 序列化--- Kryo使用简单例子

简单示例

Kryo kryo = new Kryo();        Input input = null;        input = new Input(new FileInputStream(fileName));        BackupQueueData queueData = kryo.readObject(input, BackupQueueData.class);

Kryo kryo = new Kryo();         Output output = null; output = new Output(new FileOutputStream(fileName));         kryo.writeObject(output, queueData);

 

Kryo.Pool

KryoFactory factory = new KryoFactory() {            public Kryo create() {               Kryo kryo = new Kryo();               returnkryo;            }        };        // Simple pool, you might also activate SoftReferences to fight OOMEs.        KryoPool pool = new KryoPool.Builder(factory).build();        Kryo kryo = pool.borrow();        Output output = new Output(new FileOutputStream("Test.file"));        TestBean tb = new TestBean();        tb.setId(1L);        tb.setAge(20);        kryo.writeObject(output, tb);        output.close();        pool.release(kryo);          // or use a callback to work with kryo (pool.run borrows+releases for        // you)               TestBean value = pool.run(new KryoCallback<TestBean>() {            public TestBean execute(Kryo kryo) {               Input input;               try {                   input = new Input(new FileInputStream("Test.file"));                   returnkryo.readObject(input, TestBean.class);               } catch (FileNotFoundException e) {                   // TODO Auto-generated catch block                   e.printStackTrace();               }               returnnull;            }        });         System.out.println(value.getId());                 System.out.println(value.getAge());

Kryo池并不复杂，提供了除了直接构建Kryo实例之外的另一种是用方式。
