服务端：
- Java code
public void showById() throws IOException { //接收客户端传来的商品ID BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream())); String goodsid1=br.readLine(); int goodsid = Integer.parseInt(goodsid1); System.out.println(goodsid); //可以读出 ObjectOutputStream oos = new ObjectOutputStream(s.getOutputStream()); //遍历集合 for(int i = 0 ; i< goodsData.size(); i++) { ShopGoods sg = goodsData.get(i); //查询单品 if(sg.getGid()==goodsid) { oos.writeObject(goodsData); System.out.println("ssssssssss"); //此行读不出} } }
客户端：
- Java code
public void getGoodsTable() throws IOException, ClassNotFoundException { BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream())); System.out.println("请输入您要查询的商品编号："); goodsid = br.readLine(); bw.write(goodsid); bw.flush(); bw.close(); br.close(); System.out.println("商品编号"+"\t\t"+"商品名称"+"\t\t"+"商品单位"+"\t\t"+"商品价格"+"\t\t"+"商品数量"); ois = new ObjectInputStream(s.getInputStream()); ArrayList<ShopGoods> goodsData =(ArrayList<ShopGoods>)ois.readObject(); for (ShopGoods sg : goodsData) { System.out.println(" "+sg.getGid()+"\t\t"+sg.getGname()+"\t"+" "+ sg.getGmean()+"\t\t"+" "+sg.getGprice()+"\t\t"+" "+sg.getGnum()); } }
客户端报错：socket is closed；
服务端报错：oftware caused connection abort: socket write error；
------解决方案--------------------
就用List传一次，希望能给你点帮助吧：
Server：
- Java code
try{ ServerSocket ss=new ServerSocket(8090); System.out.println("我是服务器，在8090端口监听"); Socket s=ss.accept(); //读取客户端的信息 ObjectInputStream ois = new ObjectInputStream(s.getInputStream()); User user = (User) ois.readObject(); System.out.println("name:"+user.getName()+"\npassword"+user.getPassword()); List<String> list = new ArrayList<String>(); list.add("测试语句"); ObjectOutputStream oos = new ObjectOutputStream(s.getOutputStream()); oos.writeObject(list); }catch(Exception ex) { ex.printStackTrace(); }
