我在进行图片上传和显示操作其中，struts2的相关action源码如下

public class GoodsAction {
@Autowired

private String phPinpai;
private String phXinghao;
private double phJiage;
private String phXitong;
private String phWeb;
private String phRam;

private File phTupian;
private String phChicun;
private int phKucun;
public String GoodsInfo()
{
ActionContext ctx=ActionContext.getContext();
List<Goods> goodsinfo=goodsService.findAll();
ctx.put("goodsinfolist", goodsinfo);
return "goods_info";
}
public String GoodsDelete()
{
ActionContext ctx=ActionContext.getContext();
goodsService.deleteGoodsInfo(getPhXinghao());
return "goods_info";
}
public String GoodsAdd() throws FileNotFoundException, IOException
{
Goods goods=new Goods();
goods.setPhChicun(getPhChicun());
goods.setPhCpu(getPhCpu());
goods.setPhJiage(getPhJiage());
goods.setPhKucun(getPhKucun());
goods.setPhPinpai(getPhPinpai());
goods.setPhRam(getPhRam());
goods.setPhRom(phRom);
FileInputStream in=new FileInputStream(getPhTupian());
byte[] bt=new byte[in.read()];
goods.setPhTupian(bt);
goods.setPhWeb(getPhWeb());
goods.setPhXinghao(getPhXinghao());
goods.setPhXitong(getPhXitong());
goodsService.addGoodsInfo(goods);
return "goods_info";
}
……get和set方法省略,页面显示信息使用的<s:iterator>来显示list内容，但是显示不出来图片，如何才能显示图片呢，请大家指导一下
