最近用到webuploader的图片上传，网上查了好多资料，奈何php看不懂，就是没有java后台代码，都说就是按平时的图片上传操作，昨晚有时间直接试了试，发现没有想象
中那么复杂，上传的处理那个路径修改后，用file接收，如果方法里面有错误，页面自动提示上传失败，也没有往页面返回什么值，方法正常执行成功的话页面也会相应

变为上传成功，多个图片上传的时候每次上传图片都会调用addGoods方法；前端的那些代码是看的H-UI框架里面的，修改了一下限制图片上传的那个，image/*可能会造成chrome浏览器点击上传时延迟弹出。其他的还没细看，但是至少能上传了，成功失败也有提示，其他的还没细看，先记录一下
前台的代码网上好多，我用的是H-UI框架里的，内容挺多，没有一一研究，只看了部分重要的，修改的地方就是把请求连接改为/addGoods，然后限制图片格式上传把image/*改为image/jpg,image/jpeg,image/png,image/gif
@RequestMapping("/addGoods")
public String addGoods(MultipartFile file, HttpServletRequest request, HttpServletResponse response) throws IOException{
File photo = null;
String bathPath = request.getSession().getServletContext().getRealPath("/");
File firstFolder = new File(bathPath+"/photos");
File secondFolder = new File(firstFolder+"/"+"1005101");
String fileName = file.getOriginalFilename();
if(!firstFolder.exists()) {
firstFolder.mkdirs();
}else if(!secondFolder.exists()){
boolean b = secondFolder.mkdirs();
}else{
photo = new File(secondFolder+"/",fileName);
}
file.transferTo(photo);
System.out.println(file.getOriginalFilename()+"上传成功");
return "goods/goodsInStockList";
