JAVA放数据到memcached时序列化

我想放N条记录到一个list中，然后把list放到memcached中。
[code="java"]
List addlist; // 待放入缓存list

class Info {
private String s1;
private String s2;
private String s3;
private User user;
private List customerList;

/*

• getter and setter */

}
[/code]

问题是：如何实现放入的list的序列化？

[code="java"]
class Info [color="red"implements java.io.Serializable[/color] {

private String s1;

private String s2;

private String s3;

private User user;

private List customerList;

[/code]
