java - 对象反序列化 - 从序列化对象中获取 int 数组

Question

int[] myIntArray;
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(1024);
ObjectOutputStream objectOutputStream = new ObjectOutputStream(new DeflaterOutputStream(byteArrayOutputStream));
objectOutputStream.writeObject(myIntArray);

现在，ObjectOutputStream 获取该对象并直接序列化它。 DeflaterOutputStream 压缩序列化结果，然后将压缩结果存储在 ByteArrayOutputStream

有人可以告诉我如何反序列化并取回我原来的 int 数组吗？请分享代码吗？

Answer 1

objectOutputStream.close();
byte[] serialized = byteArrayOutputStream.getBytes();

// and then read back using symmetric constructs as when writing, but using 
// input streams instead of output streams:

ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(serialized);
ObjectInputStream objectInputStream = 
    new ObjectInputStream(new InflaterInputStream(byteArrayInputStream));
int[] myDesererializedIntArray = (int[]) objectInputStream.readObject();
