java.lang.IllegalArgumentException: Invalid character found in method name. HTTP method names must be tokens

服务器没人访问,开着日志,发现个报错,但也不影响系统正常运行

2016-11-16 15:49:54,447 [http-bio-80-exec-41][IP:|USER:][DEBUG org.springframework.web.servlet.DispatcherServlet] Successfully completed request

INFO: Error parsing HTTP request header
Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.

经过查阅资料发现是Tomcat的header缓冲区大小不够,只需要在server.xml中增加maxHttpHeaderSize字段即可:


<Connector URIEncoding="UTF-8" port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol"
	useBodyEncodingForURI="false"
	enableLookups="false"
        connectionTimeout="20000"
        redirectPort="8443" maxHttpHeaderSize="8192"/>
