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!
