上传文件报错：The current request is not a multipart request] with root cause

上传文件时报错：The current request is not a multipart request] with root cause

解决：在

标签加上  ：  enctype="multipart/form-data"  

参考：

上传文件的表单中要加属性enctype="multipart/form-data",如果不写enctype属性时，也默认为其添加了enctype属性值，默认值是enctype="application/x- www-form-urlencoded"

上传文件报错：upload file springboot Required request part 'file' is not present

长传文件报错：Required request part 'file' is not present

解决：1、请查看参数名称等是否匹配；

           2、@RequestMapping注解加上：consumes = "multipart/form-data"，如下：

@RequestMapping(value = "/form", method = RequestMethod.POST, consumes = "multipart/form-data")
 public String handleFormUpload(@RequestPart("file") MultipartFile 
 file)
