信息: Error parsing HTTP request header
Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.
java.lang.IllegalArgumentException: Invalid character found in method name. HTTP method names must be tokens

将SSLEngine="on"改为off后，重启。
<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="off" />
网上其他参考方案：
1.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="你想要的大小"/>
2.可能是因为请求协议不对，需要统一成https或http请求。
