[英]Java Spring boot 2.0.5 MultipartFile upload “Content type not supported”
I have a project with Spring boot and I'm trying to upload a file. 我有一个使用Spring Boot的项目,我正在尝试上传文件。
I'm using multipart/form-data on my form and @RequestPart in my Controller. 我在表单上使用multipart / form-data,在Controller中使用@RequestPart。 Although all the tutorials and solutions recommended to use @RequestParam, it doesn't seem to work anymore or just for me.
尽管所有教程和解决方案都建议使用@RequestParam,但它似乎不再起作用或仅对我有用。
I got over the problem of not getting the post request parameter by using @RequestPart but now the browser gives @Content type not supported" error. 我克服了无法通过使用@RequestPart获取发布请求参数的问题,但是现在浏览器给出了@Content type not support”错误。

I have a feeling that it might have something to do with being newer versions of Spring boot for example. 我有一种感觉,例如它可能与Spring Boot的较新版本有关。 I tried out example on page http://www.mkyong.com/spring-boot/spring-boot-file-upload-example/ and it worked but when I used the same HTML and Controller in my project then I got the same error as before.
我在页面http://www.mkyong.com/spring-boot/spring-boot-file-upload-example/上尝试了示例,它可以正常工作,但是当我在项目中使用相同的HTML和Controller时,我得到了相同的结果与以前一样的错误。
Thanks 谢谢
and add the following in application.properties 并在application.properties中添加以下内容
multipart.enabled=true
multipart.file-size-threshold=0 # Threshold after which files will be written to disk.
multipart.location=# Intermediate location of uploaded files.
multipart.max-file-size=1Mb # Max file size.
multipart.max-request-size=10Mb # Max request size.
