How do you make a deep copy of an object?

Question

It\'s a bit difficult to implement a deep object copy function. What steps you take to ensure the original object and the cloned one share no reference?

Answer 1

For Spring Framework users. Using class org.springframework.util.SerializationUtils:

@SuppressWarnings("unchecked")
public static  T clone(T object) {
     return (T) SerializationUtils.deserialize(SerializationUtils.serialize(object));
}
