Ⅰ spring boot 多文件上传 MultipartFile[] 获得不到值
这个感觉是你的请求没带着文件,所以过滤器不会将httprequest处理为multipartrequest,请求应该类似下面这样的
如果你的请求不是这样的,而是普通的请求,转的时候就会失败
Ⅱ spring mvc 多文件上传时报错MultipartHttpServletRequest
1、确认<form name="contractForm" id="contractForm" action="" method="post" enctype ="multipart/form-data">;
2、确认commons-fileupload.jar 和 org.springframework.web.jar 存在环境
3、MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest)request;
这一句会报错:ApplicationHttpRequest cannot be cast to MultipartHttpServletRequest
解决办法是通过这种方式:
MultipartResolver resolver = new CommonsMultipartResolver(request.getSession().getServletContext());
MultipartHttpServletRequest multipartRequest = resolver.resolveMultipart(request);
Ⅲ springmvc 多文件上传multipartfile 怎么获取前台传过来的参数
@RequestMapping("fileUpload")
public String fileUpload(@RequestParam("file") MultipartFile file) {
}
