如何在 Spring-MVC 中处理 ClientAbortException？

Question

每当客户端中止连接时，我都会得到ClientAbortException如下记录：

org.apache.catalina.connector.ClientAbortException: java.io.IOException: APR error: -730053
    at org.apache.catalina.connector.OutputBuffer.doFlush(OutputBuffer.java:353) ~[catalina.jar:8.0.26]
    at org.apache.catalina.connector.OutputBuffer.flush(OutputBuffer.java:317) ~[catalina.jar:8.0.26]
    at org.apache.catalina.connector.CoyoteOutputStream.flush(CoyoteOutputStream.java:110) ~[catalina.jar:8.0.26]

    at com.fasterxml.jackson.databind.ObjectWriter.writeValue(ObjectWriter.java:891) ~[jackson-databind-2.6.5.jar:2.6.5]
    at org.springframework.http.converter.json.AbstractJackson2HttpMessageConverter.writeInternal(AbstractJackson2HttpMessageConverter.java:264) ~[spring-web-4.2.4.RELEASE.jar:4.2.4.RELEASE]
    at org.springframework.http.converter.AbstractGenericHttpMessageConverter.write(AbstractGenericHttpMessageConverter.java:100) ~[spring-web-4.2.4.RELEASE.jar:4.2.4.RELEASE]

问题：因为我不在乎客户端是否中止连接，所以我想阻止日志记录。或者，防止我的应用程序尝试实际返回响应。

我怎么能这样做？

我可以创建某种全局@ExceptionHandler(ClientAbortException.class)但void如果我发现任何返回吗？

至少从 Spring Boot 2.3.4（可能更早）开始，您可以@ControllerAdvice通过以下方法使用带注释的类：

  @ExceptionHandler(ClientAbortException.class)
  public void handleLockException(ClientAbortException exception, HttpServletRequest request) {
    final String message = "ClientAbortException generated by request {} {} from remote address {} with X-FORWARDED-FOR {}";
    final String headerXFF = request.getHeader("X-FORWARDED-FOR");
    log.warn(message, request.getMethod(), request.getRequestURL(), request.getRemoteAddr(), headerXFF);
  }
