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

在选择springcloud作为微服务框架时，我们使用远程RPC调用接口，此时我们选择Feign声明式服务调用，简单易用,

可以直接继承接口，注入使用，那此时在文件上传时，变出现了问题，FeignClient调用接口时不支持上传文件；于是找到了githup找到一个开源的工具包，

引入在pom文件中加入

 

 

       <!--解决不能传递表单参数的问题-->
        <dependency>
            <groupId></groupId>
            <artifactId>feign-form</artifactId>
            <version>3.3.0</version>
        </dependency>
        <dependency>
            <groupId></groupId>
            <artifactId>feign-form-spring</artifactId>
            <version>3.3.0</version>
        </dependency>

在使用FeignClient时带上参数

@FeignClient(name = "feign-service",configuration = )
public interface FeignService{
    @RequestMapping(value = "/uploads", method = , consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
    String uploads(@RequestPart("file") MultipartFile file);
}

注意，参数注解是@RequestPart

注意，注意，因为Springcloud的对应的feign-form版本不对则会出现以下问题，

Springboot version(1.)

Springcloud version(Dalston.RC1)

feign-form对应的版本是<version>3.3.0</version>，

而我使用的是spring boot() srpingcloud(Greenwich.SR1)

feign-form对应的版本是<version>3.3.0</version>,

就不会出现这种问题了，版本不对称，找起来也费劲
