问题描述
我在进行图片上传和显示操作其中，struts2的相关action源码如下/* * To change this template, choose Tools | Templates * and open the template in the editor. */package bphone.action;import bphone.iservice.IGoodsService;import bphone.model.Goods;import com.opensymphony.xwork2.ActionContext;import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;/** * * @author RZB */public class GoodsAction { @Autowired private IGoodsService goodsService; private String phPinpai; private String phXinghao; private double phJiage; private String phXitong; private String phWeb; private String phRam; private String phRom; private String phCpu; 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
解决方案
你需要单独写一个action 然后返回图片的流信息（直接响应返回） 设置mime类型为图片的<img src="action地址?id=图片id">
