Spring Boot Webapplication文件上载（.war）

我有个问题。我做了一个小的申请，以获得在春季开机。 我添加了一个文件上传功能，该功能适用于我的.jar。现在，我想在Tomcat8上部署应用程序，但文件上传不再起作用。 我想问题是上传文件夹的目录

这：

@GetMapping("/uploadForm")
      public String listUploadedFiles(Model model) throws IOException {

      model.addAttribute("files", fileSystemStorageService.loadAll().map(
          path -> MvcUriComponentsBuilder.fromMethodName(FileUploadController.class,
              "serveFile", path.getFileName().toString()).build().toString())
          .collect(Collectors.toList()));

这似乎就是问题所在。在.jar文件中，可以找到upload dir文件夹。 但我不知道如何把它变成一场战争。 Spring Boot在战争中需要上传文件夹的地方

谢谢你

这里有更多的信息

这是我的Stacktrace：

我是这么说的，它可以与.jar打包一起使用，但是如果我在Tomcat上使用它作为.war…
