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 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"/>如：
<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"/>
