Java 如何在SpringMVC中处理ClientBortException？

每当客户端中止连接时，我都会得到一个

ClientAbortException

日志，如下所示：

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]

问题：由于我不关心客户端是否中止连接，所以我希望阻止日志记录。或者，阻止我的应用程序尝试实际返回响应

我怎么能这样做

---

我是否可以创建某种全局

@ExceptionHandler（ClientAbortException.class）

，但如果捕获到任何异常，则返回

void

？

我也遇到了同样的问题，我无法使用Spring MVC和异常处理程序执行您所说的操作。有些异常（我猜是未经检查的）没有被SpringMVC处理程序记录。我所做的是在web.xml中定义一个通用过滤器

  <!-- Filter for exception handling, for those exceptions don't catched by Spring MVC -->
  <filter>
    <filter-name>LoggerFilter</filter-name>
    <filter-class>com.myproject.commons.filters.ExceptionLoggerServletFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>LoggerFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

---

由于至少Spring Boot 2.3.4（可能更早），您可以通过以下方法使用

@ControllerAdvice

注释类：

  @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);
  }

---

这正是我最后处理它的方式：添加一个

void

方法，全局捕获

ClientAbortException

，就像您所做的那样@Ortomala您是如何在ControllerAdvice中使用ClientBortException的？

  @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);
  }
