解决：Invalid character found in method name. HTTP method names must be tokens
阿里云上弄了一个tomcat，经常半夜发送崩溃，查看日志发现这个东西，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 port="8080" executor="tomcatThreadPool" protocol="HTTP/1.1" maxThreads="1000" maxHttpHeaderSize="8192" minSpareThreads="100" maxSpareThreads="200" acceptCount="1000" maxConnections="1000" connectionTimeout="30000" keepAliveTimeout="15000" maxKeepAliveRequests="1" tcpNoDelay="true" redirectPort="8443" enableLookups="false" URIEncoding="UTF-8"/>
