Today, I would like to share with you the relevant knowledge points about how to deal with Feign remote call Multipartfile parameters. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look.

Feign remote call Multipartfile parameter

The problem encountered when writing business code today is that the front end requests A service to give the parameters to A service correctly, but when A service invokes B service, it throws the file parameters, which can not be received there, and will report an error in Multipartfile parameters.

The answer has been found on the Internet, and here is a record:

Solution

It has to be.

Create a new configuration class where your fegin service interface is exposed.

Package com.gobon.gbjk.file.api.config;import feign.form.spring.SpringFormEncoder;import org.springframework.beans.factory.ObjectFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.autoconfigure.http.HttpMessageConverters;import org.springframework.cloud.openfeign.support.SpringEncoder;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;/** *

* feign configuration class *

* * @ projectName: gbjk-user * @ package: com.gobon.gbjk.file.api.config * @ className: FeignSupportConfig * @ author: wen jun tang * @ date: 12:25, December 21, 2021 * @ version: 1.0 * / @ Configurationpublic class FeignSupportConfig {@ Autowired private ObjectFactory messageConverters; @ Bean public SpringFormEncoder feignFormEncoder () {return new SpringFormEncoder (new SpringEncoder (messageConverters));}}

Then modify your interface file parameters with @ RequestPart:

@ PostMapping (value = "/ file/upload", consumes = MediaType.MULTIPART_FORM_DATA_VALUE) AjaxResult upload (@ RequestPart ("file") MultipartFile file, @ RequestParam ("bucketName") String bucketName)

Call again, perfect solution!

The problem of passing parameters in Feign remote call

If it is a simple parameter, annotate with @ RequestParam or @ PathVariable

If it is an object parameter, annotate with @ RequestBody
