对象流的使用(ObjectInputStream和ObjectOutputStream)

import java.io.Serializable;

public class Person implements Serializable {

	private static final long serialVersionUID = 1L;

	private String name;

	public Person() {
		super();
	}

		this.name = name;
	}

	public Long getId() {

	}

	public void setId(Long id) {
		this.id = id;
	}

	@Override
	public String toString() {
		return "Person [name=" + name + ", id=" + id + "]";
	}

}
