JAVA对象和字节数组互转
0x01 创建要转换的类和主函数
注意这里一定要实现序列化
package day1;
import java.io.Serializable;
public class Test360 implements Serializable {
@Override
public String toString() {
return "Test360{" +
"name='" + name + '\'' +
'}';
}
String name="test";
}
0x02 对象和字节数组互转
package day1;
import sun.jvm.hotspot.utilities.Assert;
import java.io.*;
public class arreytobytes {
public static void main(String[] args) throws Exception {
Test360 test =new Test360();
System.out.print ( "java class对象转字节数组\n" );
byte[] bufobject = getBytesFromObject(test);
for(int i=0 ; i<bufobject.length ; i++) {
System.out.print(bufobject[i] + ",");
}
System.out.println ("\n");
System.out.print ("字节数组还原对象\n");
Object object1 = null;
object1=deserialize(bufobject);
Test360 t1 =(Test360)object1;
System.out.println (t1.name);
}
public static byte[] getBytesFromObject(Serializable obj) throws Exception {
if (obj == null) {
return null;
}
ByteArrayOutputStream bo = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(bo);
oos.writeObject(obj);
return bo.toByteArray();
}
public static Object deserialize(byte[] bytes) {
Object object = null;
try {
ByteArrayInputStream bis = new ByteArrayInputStream(bytes);//
ObjectInputStream ois = new ObjectInputStream(bis);
object = ois.readObject();
ois.close();
bis.close();
} catch (IOException ex) {
ex.printStackTrace();
} catch (ClassNotFoundException ex) {
ex.printStackTrace();
}
return object;
}
}
运行结果
