SpringBoot：Invalid character found in method name. HTTP method names must be tokens

问题背景

关于SpringBoot应用挂了很久之后，会发生Invalid character found in method name. HTTP method names must be tokens的问题。


java.lang.IllegalArgumentException: Invalid character found in method name. HTTP method names must be tokensat org.apache.coyote.http11.Http11InputBuffer.parseRequestLine(Http11InputBuffer.java:426) ~[tomcat-embed-core-8.5.29.jar:8.5.29]at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:687) ~[tomcat-embed-core-8.5.29.jar:8.5.29]at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:66) [tomcat-embed-core-8.5.29.jar:8.5.29]at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:790) [tomcat-embed-core-8.5.29.jar:8.5.29]at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1459) [tomcat-embed-core-8.5.29.jar:8.5.29]at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) [tomcat-embed-core-8.5.29.jar:8.5.29]at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1135) [na:na]at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) [na:na]at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) [tomcat-embed-core-8.5.29.jar:8.5.29]at java.base/java.lang.Thread.run(Thread.java:844) [na:na]

网上方案

据说是tomcat 的设置问题，如果出现相关情况，可以设置一下application.yml文件的tomcat下的max-http-header-size即可。

server:port: 5555servlet:context-path: /xxxxtomcat:remote-ip-header: x-forward-foruri-encoding: UTF-8max-threads: 1000max-http-header-size: 8096

实际情况

发现是正常的http请求，发送为https请求。
例如正常路径为http://localhost:8080/xxxx，现在变成请求https://localhost:8080/xxxx就会报错。(似乎跟项目没有什么关系).

猜测

可能是tomcat8.5的keepalive有关,检测自己http协议的时候顺便检测了自己的https协议,有很多人遇到半夜报错或者隔了一段时间报错,目前这个bug没搜索到很多定论,可以尝试加tomcat的connection-timeout

parseRequestLine

报错的地方代码如下
