Description:

First of all, this error is reported by gateway gateway

The reason for the error is that the size of the image uploaded on the web service exceeds the configuration of spring. Servlet. Multipart. Max file size = 10MB, but it is intercepted in the file Upload Interceptor of the web service and gives a friendly response. I don't know why the gateway reported this mistake

Ask the great God to answer

@niuzhimin Most probably this is a duplicate to #1478. Please check your Spring Cloud Gateway version.

@violetagg The spring cloud gateway version is 2.1.1 I just had a look #1478 I don't see the solution。Can you give us a detailed answer please

[niuzhimin]

@violetagg Why and how to solve this problem? Is it related to the gateway version?

[violetagg]

@niuzhimin This has been fixed in Reactor Netty v1.0.4 which is Spring Cloud Gateway v3.0.2. Yes you need to update your Spring Cloud Gateway version.

The fix that was made is that you will receive the original error from the server i.e. error code 400, describing that the upload size is invalid.

What is the corresponding version of springboot?

[violetagg]

What is the corresponding version of springboot?

Spring Boot v2.4.3/v2.5.0

[niuzhimin]

Does it have to be this high?

[violetagg]

Does it have to be this high?

I didn't get it

Reactor Netty 1.0.4 (where the fix was included for the first time) is available with Spring Boot v2.4.3.
Spring Boot v2.5.0 contains the fix from the very beginning.

Well, I mean, is it compatible with other versions? If the spring boot version is 2.4.3, the cloud service version must be the latest. Is there any other solution? As long as the gateway does not report an error and gives a friendly prompt that the upload of files is restricted

That should be discussed with Spring Cloud Gateway maintainers ...
