处理 RequestRejectedException - ExceptionLoggingFilter
Handling RequestRejectedException - ExceptionLoggingFilter
当用户在请求中缺少一个参数时，我收到了这个错误，它像 www.foo.com/fooId//info 一样抛出 RequestRejectedException 并向用户返回 500 错误。
错误日志：
o.s.c.s.i.web.ExceptionLoggingFilter : Uncaught exception thrown
org.springframework.security.web.firewall.RequestRejectedException: The request was rejected because the URL was not normalized.

为了捕获这个异常，我添加了这个过滤器：
@Component
@Slf4j
@Order(Ordered.HIGHEST_PRECEDENCE)
public class RequestRejectedExceptionHandler extends OncePerRequestFilter {
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
throws ServletException, IOException {
try {
filterChain.doFilter(request, response);
} catch (RequestRejectedException e) {
log.error("400 - Bad Request");
response.setStatus(400);
response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
}
}
}
现在在 postman 中，它返回了我想要的 400 错误请求，但是在我的日志中，我可以看到这个错误仍然被记录为未被捕获，并且不太清楚为什么并需要一些建议：

如果您看到这些日志，您可能使用了不受支持的 Spring Cloud Sleuth 版本。
来自 o.s.c.s.i.web.ExceptionLoggingFilter 的日志来自 Spring Cloud Sleuth 依赖项。
ExceptionLoggingFilter 旨在帮助日志关联。来自参考文档
Sleuth configures the logging context with variables including the service name (%{spring.zipkin.service.name}) and the trace ID (%{traceId}). These help you connect logs with distributed traces and allow you choice in what tools you use to troubleshoot your services.
Once you find any log with an error, you can look for the trace ID in the message.
在这种情况下，ExceptionLoggingFilter 可能会在您的自定义过滤器之前执行。
请注意，ExceptionLoggingFilter 自 Spring Cloud Sleuth 2.2.3 起默认禁用，并在 3.x 中完全删除。
如果您升级到受支持的 Sleuth 版本，您将看不到这些日志。
在 3.1.x 中，我们添加了对 Tomcat Valve 仪表的支持，因此不再需要 ExceptionLoggingFilter。我们将检测来自 tomcat.
内的所有日志
当用户在请求中缺少一个参数时，我收到了这个错误，它像 www.foo.com/fooId//info 一样抛出 RequestRejectedException 并向用户返回 500 错误。

如果您看到这些日志，您可能使用了不受支持的 Spring Cloud Sleuth 版本。
来自 o.s.c.s.i.web.ExceptionLoggingFilter 的日志来自 Spring Cloud Sleuth 依赖项。
ExceptionLoggingFilter 旨在帮助日志关联。来自参考文档
Sleuth configures the logging context with variables including the service name (%{spring.zipkin.service.name}) and the trace ID (%{traceId}). These help you connect logs with distributed traces and allow you choice in what tools you use to troubleshoot your services. Once you find any log with an error, you can look for the trace ID in the message.
在这种情况下，ExceptionLoggingFilter 可能会在您的自定义过滤器之前执行。
请注意，ExceptionLoggingFilter 自 Spring Cloud Sleuth 2.2.3 起默认禁用，并在 3.x 中完全删除。
如果您升级到受支持的 Sleuth 版本，您将看不到这些日志。
在 3.1.x 中，我们添加了对 Tomcat Valve 仪表的支持，因此不再需要 ExceptionLoggingFilter。我们将检测来自 tomcat.
