一、该问题的重现步骤是什么？

1. post请求，上传文件大于20MB

#服务器端口

server:

port: 9670

undertow:

# 允许的最大查询或路径参数数默认1000

max-parameters: 5000

tomcat:

# 吞了量-1 不限制，默认2M

max-swallow-size: -1

#数据源配置

spring:

servlet:

multipart:

enabled: true

max-file-size: 20MB

max-request-size: 150MB

后台使用,下面方式捕获：

@Slf4j

@Order(Ordered.HIGHEST_PRECEDENCE + 100)

@Configuration(proxyBeanMethods = false)

@ConditionalOnWebApplication(type = ConditionalOnWebApplication.Type.SERVLET)

@ConditionalOnClass({Servlet.class, DispatcherServlet.class})

@RestControllerAdvice

public class XXXXXRestExceptionTranslator {

@Value("${server.tomcat.max-swallow-size}")

private Integer mss;

@Value("${spring.servlet.multipart.max-file-size}")

private String mfs;

@Value("${spring.servlet.multipart.max-request-size}")

private String mrs;

@ExceptionHandler(MultipartException.class)

@ResponseStatus(HttpStatus.BAD_REQUEST)

public R handleError(MaxUploadSizeExceededException e) {

log.error("上传文件异常,单个文件不能大于{}，全部文件不能大于{},tomcat吞吐量{}", mfs, mrs, mss,e);

String mess = String.format("上传文件异常,单个文件不能大于%s，全部文件不能大于%s,tomcat吞吐量%s", mfs, mrs, mss);

return R.fail(ResultCode.FAILURE, mess);

}

捕获成功，但是浏览器得不到响应，出现net::ERR_CONNECTION_RESET问题

Proxy error: Could not proxy request //refund-platform/provincial/api/branchOfficeApply from 192.168.173.176:18000 to http://192.168.173.176:9670.

See https://nodejs.org/api/errors.html#errors_common_system_errors for more information (ECONNRESET).

二、你期待的结果是什么？实际看到的又是什么？

前端可以获得返回值

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

bladex-biz，2.8.0.RELEASE 商业版 idea

四、请提供详细的错误堆栈信息，这很重要。
