Java 春云门户：获取；在发送请求正文时，响应前已关闭连接；发布大文件时出错

我有一个运行在SpringCloud网关后面的SpringBoot应用程序

spring启动应用程序控制器：

@PostMapping(value = "hi")
public String postHi(@RequestHeader HttpHeaders headers, HttpServletRequest request) {
  return request.getHeader("Content-Length");
}

Spring云网关路由配置：

spring:
  cloud:
    gateway:
      routes:
        - id: hi
          uri: http://localhost:8080/hi
          predicates:
            - Path=/hi/**

因此，当我通过邮递员请求上传小文件（大小：1000KB）时，我没有收到任何错误，但当文件较大（大小：10MO）时，我收到以下错误：

{
    "timestamp": "2019-12-10T20:52:33.554+0000",
    "path": "/hi",
    "status": 500,
    "error": "Internal Server Error",
    "message": "Connection has been closed BEFORE response, while sending request body",
    "requestId": "ad589017"
}

使用此堆栈：

reactor.netty.http.client.PrematureCloseException: Connection has been closed BEFORE response, while sending request body
    Suppressed: reactor.core.publisher.FluxOnAssembly$OnAssemblyException: 
Error has been observed at the following site(s):
