org.apache.tomcat.util.http.fileupload.FileItemIterator hasNext 返回 false

Question

我正在从事从 j2ee 到 Springboot 的迁移项目。我确实很难在 Spring Boot 中上传文件。正如在J2EE应用程序中使用“org.apache.tomcat.util.http.fileupload”来上传文件一样，我认为spring-boot已经嵌入了tomcat，它可以工作，但不幸的是它没有。我必须与 Multipart 一起工作。我不能在任何时候让它为假。我用 apache common 尝试过的同样的事情最终得到了相同的结果。这是我的代码..您能否建议我如何进行..您的帮助将不胜感激..

我也有两个过滤器。我使用邮递员进行测试

我改变了我的映射如下，它开始工作......

@RequestMapping(value = "document/{DocType}",method =RequestMethod.POST)
    public ResponseData fileUpload(@PathVariable("DocType") String docType, @RequestParam("pdf") MultipartFile[] multipartfiles,HttpServletRequest request){
ResponseData responseData =  new ResponseData();
System.out.println("your code in between...");

return responseData;
}
