Question

我收到错误：＆＃34;方法有太多的身体参数＆＃34; 在尝试生成Spring Feign客户端时

@RequestMapping(value="/media", method=RequestMethod.POST)
String uploadMedia(@RequestHeader("Authentication") String token,
    @RequestPart("media") MultipartFile audio, 
    @RequestPart("a-json-object") SomeClass someClazz,
    @RequestPart("another-json-object") AnotherClass anotherClazz);

我找到了以下解决方案，它在使用常规Feign注释时有效，但在Spring MVC注释时无效：

'Too many body parameters' Exception on Feign Client

现在应该可以。添加以下依赖项：

<dependencies>
...
<dependency>
    <groupId>io.github.openfeign.form</groupId>
    <artifactId>feign-form</artifactId>
    <version>2.2.0</version>
</dependency>
<dependency>
    <groupId>io.github.openfeign.form</groupId>
    <artifactId>feign-form-spring</artifactId>
    <version>2.2.0</version>
</dependency>
...

并使用此客户端配置：

@FeignClient(name = "file-upload-service", configuration = FileUploadServiceClient.MultipartSupportConfig.class)
public interface FileUploadServiceClient extends IFileUploadServiceClient {

    @Configuration
    public class MultipartSupportConfig {

        @Bean
        @Primary
        @Scope("prototype")
        public Encoder feignFormEncoder() {
            return new SpringFormEncoder();
        }
    }
}

示例来自：feign-form docs

我可以使用Multipart参数生成Spring Feign客户端吗？
