记录Springcloud feign 文件上传报错 FileUploadException: the request was rejected because no multipart bounda

记录一次使用feign接口调用第三方接口上传文件报错排错新得（项目环境比较老，新版本的SpringCloud SpringBoot使用没有出现问题）

项目环境

:: Spring Boot :: (v1.5.12.RELEASE)
spring-cloud-starter-1.3.3.RELEASE

pom

这里需要注意的是，需要找到你所有对应的fegin表单上传插件版本，之前我换的版本太高了也会导致识别不了
