可以将第一张图片和第二张图片的处理分开，分别判断是否存在并保存即可。以下是修改后的代码示例：

@RequestMapping(value = "/image.action")
public String upload(@RequestParam(value ="image", required = false) MultipartFile file, @RequestParam(value ="image1", required = false) MultipartFile file1, HttpServletRequest request, ModelMap model) {
    String path = request.getSession().getServletContext().getRealPath("/") + "upfiles/";
    // 保存第一张图片
    if (file != null && !file.isEmpty()) {
        String fileName = file.getOriginalFilename();
        int i = fileName.lastIndexOf(".");
        String name = String.valueOf(VeDate.getStringDatex());
        String type = fileName.substring(i + 1);
        fileName = name + "." + type;
        File targetFile = new File(path, fileName);
        if (!targetFile.exists()) {
            targetFile.mkdirs();
        }
        try {
            file.transferTo(targetFile);
        } catch (Exception e) {
            e.printStackTrace();
        }
        model.addAttribute("imageFileName", fileName);
    }
    // 保存第二张图片
    if (file1 != null && !file1.isEmpty()) {
        String fileName1 = file1.getOriginalFilename();
        int j = fileName1.lastIndexOf(".");
        String name1 = String.valueOf(VeDate.getStringDatex());
        String type1 = fileName1.substring(j + 1);
        fileName1 = name1 + "." + type1;
        File targetFile1 = new File(path, fileName1);
        if (!targetFile1.exists()) {
            targetFile1.mkdirs();
        }
        try {
            file1.transferTo(targetFile1);
        } catch (Exception e) {
            e.printStackTrace();
        }
        model.addAttribute("image1FileName", fileName1);
    }
    return "page/saveimage";
}

这样修改后，即使上传第二张图片时也不会覆盖第一张图片了。
