springboot添加FastJsonHttpMessageConverter后使用文件下载的接口会报错

Resolved [org.springframework.http.converter.HttpMessageNotWritableException: No converter for [class org.springframework.core.io.InputStreamResource] with preset Content-Type 'application/octet-stream']

Start by reproducing the reported file-download interface after adding FastJsonHttpMessageConverter, using the HttpMessageNotWritableException as the initial failure signal. Trace how Spring Boot selects a converter for InputStreamResource with Content-Type application/octet-stream; done means the file download completes without the converter error.
