I. preparation for upgrading Knife4j

Dependency introduction

Com.github.xiaoymin knife4j-spring-boot-starter

Annotations open

@ EnableSwagger2@EnableKnife4jpublic class SwaggerAutoConfiguration {/ /.} 2. File download API

Download garbled problem

The garbled code problem occurs because Knife4j does not support @ PostMapping file cache, so you need to convert the interface to GetMapping.

Download the file as Knife4j.txt

The file stream is empty

Configure produces = MediaType.APPLICATION_OCTET_STREAM_VALUE for GetMapping

Set the response header (note spaces and commas)

Response.setHeader ("Content-Disposition", "attachment;filename=" + URLEncoder.encode (fileName, "utf-8"))

Get request does not support request parameter cache, and it is very inconvenient to reset the parameters every time a file is downloaded.

Post request is not supported for file download

If the returned data is too large, the page will be very stuck. It is not recommended to upgrade knife4j.
