Ⅰ spring boot 多文件上傳 MultipartFile[] 獲得不到值
這個感覺是你的請求沒帶著文件,所以過濾器不會將httprequest處理為multipartrequest,請求應該類似下面這樣的
如果你的請求不是這樣的,而是普通的請求,轉的時候就會失敗
Ⅱ spring mvc 多文件上傳時報錯MultipartHttpServletRequest
1、確認<form name="contractForm" id="contractForm" action="" method="post" enctype ="multipart/form-data">;
2、確認commons-fileupload.jar 和 org.springframework.web.jar 存在環境
3、MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest)request;
這一句會報錯:ApplicationHttpRequest cannot be cast to MultipartHttpServletRequest
解決辦法是通過這種方式:
MultipartResolver resolver = new CommonsMultipartResolver(request.getSession().getServletContext());
MultipartHttpServletRequest multipartRequest = resolver.resolveMultipart(request);
Ⅲ springmvc 多文件上傳multipartfile 怎麼獲取前台傳過來的參數
@RequestMapping("fileUpload")
public String fileUpload(@RequestParam("file") MultipartFile file) {
}
