ehcache属性查询问题，如果单单往ehcache testcache中添加User对象，在查询的时候不会出问题，但是如果再往testcache添加一个对象，那就会出现查询错误

package cache;

import java.io.Serializable;

public class User implements Serializable {

	private static final long serialVersionUID = 2098760172778119467L;

	private Integer id;
	private String name;

	public User(int id, String name) {
		this.id = id;
		this.name = name;
	}

	public Integer getId() {
		return id;
	}

	public String getName() {
		return name;
	}

	public String toString() {
		return this.id + ":" + this.name;
	}
}
