我在Sping Boot 中创建一个端点时遇到了问题，它接受Multipart/Mixed。http请求似乎甚至无法到达控制器。我在一个新的Spring Boot项目（v.2.7.0）中尝试了以下http请求：
编辑（更改的代码）：我按照代努姆先生的建议，用下面的代码做了一个新计划：

@SpringBootApplication
public class MultiparttestApplication {

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

    @Bean(name = DispatcherServlet.MULTIPART_RESOLVER_BEAN_NAME)
    public StandardServletMultipartResolver multipartResolver() {
        StandardServletMultipartResolver multipartResolver = new StandardServletMultipartResolver();
        multipartResolver.setStrictServletCompliance(true);
        multipartResolver.setResolveLazily(true);
        return multipartResolver;
    }
}

控制器：

@Controller
public class MultipartTest {

    @PostMapping(path="multipartTest", consumes = MediaType.MULTIPART_MIXED_VALUE)
    public ResponseEntity<Void> multipart(@RequestPart User user) {
        System.out.println(user.getName());
        return new ResponseEntity<>(HttpStatus.OK);
    }

}

“请求：

POST http://localhost:8080/multipartTest
Content-Type: multipart/mixed; boundary=WebAppBoundary

--WebAppBoundary
Content-Type: application/json

{
  "name": "Heidi"
}

--WebAppBoundary--

但我还是得到同样的错误：

2022-06-02 11:59:07.551 ERROR 13852 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.FileUploadException: Stream ended unexpectedly] with root cause

您可以显式地配置StandardServletMultipartResolver，使其与servlet规范严格一致。这意味着它只解析multipart/form-data，而其他内容保持不变。默认情况下，此属性设置为false。
若要启用，请加入Bean来设定此。

@Bean(name = DispatcherServlet.MULTIPART_RESOLVER_BEAN_NAME)
public StandardServletMultipartResolver multipartResolver(MultipartProperties multipartProperties) {
  StandardServletMultipartResolver multipartResolver = new StandardServletMultipartResolver();
  multipartResolver.setStrictServletCompliance(true);
  multipartResolver.setResolveLazily(multipartProperties.isResolveLazily());
  return multipartResolver;
}

现在，这将使StandardServletMultipartResolver解析multipart/form-data，并将所有其他multipart/*内容单独留在控制器中处理。
