HttpServletRequest獲取參數和文件

從HttpServletRequest中獲取上傳文件及參數的方法

try {
    //下面這句必須加，不然報錯
    MultipartResolver resolver = new CommonsMultipartResolver(hsq.getSession().getServletContext());
    MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) hsq;
​
    //獲取一起跟文件傳過來的其他參數值
    String id = multipartRequest.getParameter("id");
​
    //獲取上傳上來的文件
    Map<String, MultipartFile> fileMap = multipartRequest.getFileMap();
    for (Map.Entry<String, MultipartFile> entry : fileMap.entrySet()) {
        MultipartFile file = entry.getValue();
        String fileName = file.getOriginalFilename();
        System.out.println(fileName);
        String path = "C:\\Users\\user\\Desktop\\" + fileName;
        file.transferTo(new File(path));
    }
} catch (Exception e) {
    e.printStackTrace();
}
