如何处理Spring中的ClientAbortException？
如何处理Spring中的ClientAbortException？
提问于 2016-02-17 08:18:59
每当客户端中止连接时，我将按以下方式记录一个ClientAbortException：
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 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]
at org.springframework.web.servlet.mvc.method.annotation.AbstractMessageConverterMethodProcessor.writeWithMessageConverters(AbstractMessageConverterMethodProcessor.java:222) ~[spring-webmvc-4.2.4.RELEASE.jar:4.2.4.RELEASE]问:由于我不关心客户端是否中止了连接，所以我希望阻止日志记录。或者，阻止我的应用程序试图准确地返回响应。
我怎么能这么做？
我可以创建某种全局@ExceptionHandler(ClientAbortException.class)，但如果捕捉到void，还可以返回void吗？

由于至少SpringBoot2.3.4(可能在此之前)，您可以使用带有@ControllerAdvice注释的类，并使用以下方法：
@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);

我也遇到了同样的问题，我无法按照您对Spring和异常处理程序的要求进行操作。有些异常(我想是未经检查的)不会被Spring处理程序讨论。我所做的就是在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>我的过滤器的来源是：
public class ExceptionLoggerServletFilter implements Filter {
private static Log log = LogFactory.getLog(ExceptionLoggerServletFilter.class);
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,
ServletException {
try {
chain.doFilter(request, response);
} catch (Throwable e) {
StringBuilder sb = new StringBuilder();
sb.append("Exception detected in ExceptionLoggerServletFilter:");
if (e instanceof org.apache.catalina.connector.ClientAbortException) {
// don't do full log of this error
sb.append(" ClientAbortException");
log.error(sb.toString());
} else {
log.error(sb.toString(), e);
}
throw e;
}
}
@Override
public void destroy() {
}
