java – 不存在必需的MultipartFile参数 – Spring Boot REST POST

我正在尝试进行概念验证,该概念涉及.Net系统将文件发布到Java Spring Boot应用程序上的Rest端点.我一直收到“必需参数不存在”错误.这个错误有很多SO问题,我尝试过那些没有运气的解决方案.谁能看到我做错了什么？

这是我的C#代码：

    private async Taskstem.IO.FileStream fileStream)
    {
        using (var client = _httpClientFactory())
        {
            using (var content = new MultipartFormDataContent())
            {
                content.Add(new StreamContent(fileStream),"assetFile");
                using (var message = await client.PostAsync(uri,content))
                {
                    return await message.Content.ReadAsStringAsync();
                }
            }
        }
    }

这是fiddler看到的请求：

POST http://10.0.2.2:8083/asset/1000/1001 http/1.1
Content-Type: multipart/form-data; boundary="BAC9aebd-d9ff-40ef-bcf3-4fffdd1b2c00"
Host: 10.0.2.2:8083
Content-Length: 158
Expect: 100-conTinue
Connection: Keep-Alive

--BAC9aebd-d9ff-40ef-bcf3-4fffdd1b2c00
Content-Disposition: form-data; name=assetFile

foo,bar,10
foo2,bar2,12
--BAC9aebd-d9ff-40ef-bcf3-4fffdd1b2c00--

这是我的控制器：

@RestController
@requestMapping("/asset/")
public class AssetController {
    @requestMapping(path="{merchantID}/{assetID}",method=requestMethod.POST)
    public String getAsset(
            httpServletrequest request,@requestParam("assetFile") multipartfile file,@PathVariable("merchantId") long merchantId,@PathVariable("assetId") long assetId) throws IOException
    {
        return "It worked!";
    }
}

这是我的配置：

@SpringBootApplication(exclude={MultipartAutoConfiguration.class})
public class MySpringApplication {

    public static void main(String[] args) {
        SpringApplication.run(MySpringApplication.class,args);
    }

    @Bean(name = "multipartResolver")
    public CommonsMultipartResolver multipartResolver() {
        System.out.println("multipartResolver()");
        CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
        return multipartResolver;
    }
}
