java 图片属性 java中设置图片位置

第一种方法

public String doEdit( BrandVO brandVO,@RequestParam(value="pic")MultipartFile file) throws IllegalStateException, IOException{
        //CurrentUser user = CurrentUser.getInstance();
        if(brandVO.getBrandid()!=null){//修改
            brandVO.setChangetime(new Date());//最后修改时间（取当前系统时间）
            String oddname=brandVO.getBrandpic();
            if(oddname!=null){
                new File("F:/client/images/"+oddname).delete();//删除原先的图片            
            }           
            String orgname=file.getOriginalFilename();
            String savename=UUID.randomUUID()+orgname.substring(orgname.lastIndexOf("."));//保存图片的名字唯一
            String savepath="F:/client/images/"+savename;
            FileUtils.copyInputStreamToFile(file.getInputStream(), new File(savepath));//图片存放位置
            file.transferTo(new File(savepath));
             brandVO.setBrandpic(savename);
             service.update(brandVO);
        }else{//新增
            brandVO.setCreatetime(new Date());//取创建时的时间
            brandVO.setChangetime(new Date());//最后修改时间（取当前系统时间）
            String orgname=file.getOriginalFilename();
            String savename=UUID.randomUUID()+orgname.substring(orgname.lastIndexOf("."));//保存图片的名字唯一
            String savepath="F:/client/images/"+savename;
            FileUtils.copyInputStreamToFile(file.getInputStream(), new File(savepath));//图片存放位置
            file.transferTo(new File(savepath));
             brandVO.setBrandpic(savename);
             service.add(brandVO);

        }
        return "redirect:/brand/list.action";//跳转到列表页面
    }

第二种方法

DiskFileItemFactory factory=new DiskFileItemFactory();//获得磁盘文件条目工厂
            factory.setRepository(new File(savename));
            factory.setSizeThreshold(1024*1024);
            ServletFileUpload upload=new ServletFileUpload(factory);
            OutputStream out=new FileOutputStream(new File("F:/client/images/",savename));
            InputStream ins=file.getInputStream();
            int len=0;
            byte[] buf=new byte[1024];
            while( (len = ins.read(buf) ) != -1){
                 out.write(buf, 0, len);
             }
             ins.close();
             out.close();
