org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request; nested exception is org.apache.commons.fileupload.FileUploadException: the request was rejected because no multipart boundary was found

这个异常是由于在处理上传文件时，没有找到分隔文件流的边界标识。通常这种情况是由于请求头中没有正确设置Content-Type导致的。你可以检查一下你的请求头中是否正确设置了Content-Type为multipart/form-data。另外，如果你使用的是Apache Commons FileUpload库，还需要确保你使用的是正确的版本，因为一些旧版本可能会遇到这个问题。
