How to store the object in to database(Java Serializable Object to Byte Array)

The best way to do it is to use ApacheUtils:

To Serialize:

byte[] data = SerializationUtils.serialize(yourObject);

deserialize:

YourObject yourObject = (YourObject) SerializationUtils.deserialize(byte[] data)

SerializationUtils Class:

package com.example;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

public class SerializationUtils{
public static byte[] serialize(Object obj) throws IOException {
ByteArrayOutputStream b = new ByteArrayOutputStream();
ObjectOutputStream o = new ObjectOutputStream(b);
o.writeObject(obj);
return b.toByteArray();
}

public static Object deserialize(byte[] bytes) throws IOException, ClassNotFoundException {
ByteArrayInputStream b = new ByteArrayInputStream(bytes);
ObjectInputStream o = new ObjectInputStream(b);
return o.readObject();
}
}
