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

经过调试后发现是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"/>

 

 

不过使用Web提交就不会出现这种问题,即使手机端再三强调使用的是Post方式,仍怀疑是因为使用的Get导致Header数据过长.
