解决feign实现微服务间的文件上传出现错误the request was rejected because no multipart boundary was found

项目最开始的依赖

<dependency>
	<groupId>io.github.openfeign.form</groupId>
	<artifactId>feign-form-spring</artifactId>
	<version>3.2.2</version>
</dependency>
<dependency>
	<groupId>io.github.openfeign.form</groupId>
	<artifactId>feign-form</artifactId>
	<version>3.2.2</version>
</dependency>
<dependency>
	<groupId>commons-fileupload</groupId>
	<artifactId>commons-fileupload</artifactId>
	<version>1.3.3</version>
</dependency>

说一下我怎么解决的吧，feign接口，配置，controller和参考的例子大同小异，

我是跟踪源码发现content-type会被","或";"进行转换为Map，跟踪代码为org.apache.tomcat.util.http.fileupload.FileUploadBase#getBoundary

截图

在org.apache.tomcat.util.http.fileupload.FileUploadBase.FileItemIteratorImpl#FileItemIteratorImpl抛出异常

请求头中内容为

//用户所调用的接口提交的content-type
multipart/form-data; boundary=--------------------------381278542566024683689443
//经过feign转发请求后的content-type，按英文逗号拆分刚好Map没有boundary为key的值，索引报错
multipart/form-data, multipart/form-data; charset=UTF-8; boundary=16f0f6d2c45

希望对大家有所帮助

解决方法为修改feign-form的版本

<dependency>
	<groupId>io.github.openfeign.form</groupId>
	<artifactId>feign-form-spring</artifactId>
	<version>3.6.0</version>
</dependency>
<dependency>
	<groupId>io.github.openfeign.form</groupId>
	<artifactId>feign-form</artifactId>
	<version>3.6.0</version>
</dependency>
<dependency>
	<groupId>commons-fileupload</groupId>
	<artifactId>commons-fileupload</artifactId>
	<version>1.3.3</version>
</dependency>

 我的feign版本为

<dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-starter-openfeign</artifactId>
	<version>2.1.1.RELEASE</version>
</dependency>
<dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
	<version>2.1.1.RELEASE</version>
</dependency>
