Question

我在Tomcat中收到此错误

org.apache.coyote.http11.Http11Processor.service Error parsing HTTP request header
 Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.
 java.lang.IllegalArgumentException: Request header is too large
    at org.apache.coyote.http11.Http11InputBuffer.parseHeaders(Http11InputBuffer.java:583)

我想理解文本further occurrences of HTTP header parsing errors will be logged at DEBUG level。这是否意味着将在某个时间范围内抑制解析错误，或者仅针对特定请求抑制解析错误。谁能给我这个含义的权威来源？

这与消息中所说的完全一样。此错误的所有其他实例将在DEBUG级别记录。不适用于该请求，并且可以使用一段时间。从现在到时间的尽头。或下次服务器重新启动时，以先到者为准。

您可以在1144行的源代码中看到这一点： https://github.com/apache/tomcat/blob/7.0.x/java/org/apache/coyote/http11/AbstractHttp11Processor.java

了解“请求标头太大”
