java 序列化 byte数组_在Java中使用字节数组序列化类
我在
Java中有一个带字节数组的类.当我序列化和反序列化类的对象时,字节数组的值正在改变.
我该如何解决这个问题？
请参阅示例代码：
public class Test implements Serializable{
private static final long serialVersionUID = 3455892176538865707L;
public byte[] datakey;
public static void main(String[] args) {
byte[] key=new byte[16];
Random rn = new Random(); //Trying to randomize the byte array to use as a cryptographic key
rn.nextBytes(key);
Test test = new Test();
test.datakey=key;
System.out.println("Byte Array Before serialization : "+test.datakey);
test.serializeTest(test);
Test loadedtest=test.deserializeTest();
System.out.println("Byte Array After deserialization : "+loadedtest.datakey);
}
public void serializeTest(Test test)
{
FileOutputStream fos;
try {
fos = new FileOutputStream("test.out");
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(test);
oos.flush();
oos.close();;
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public Test deserializeTest()
{
Test test=null;
String f="test.out";
try
{
FileInputStream fis = new FileInputStream(f);
ObjectInputStream ois = new ObjectInputStream(fis);
test = (Test)ois.readObject();
ois.close();
fis.close();
}
catch(FileNotFoundException ex)
{
ex.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return test;
}
}
输出：
Byte Array Before serialization : [B@15db9742
Byte Array After deserialization : [B@75b84c92
