异常三：

1、日志内容

INFO [http-nio-80-exec-16] org.apache.coyote.http11.AbstractHttp11Processor.process Error parsing HTTP request header

        at java.lang.Thread.run(Thread.java:745)2、解决办法

修改tomcat安装文件夹的 conf/server.xml，在 <Connector port=”8080″ protocol=”HTTP/1.1″ connectionTimeout=”20000″ maxHttpHeaderSize =”10240″ redirectPort=”8443″ />中，maxHttpHeaderSize的默认值是8*1024，你只需要调成你需要的值就好了。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持共生网络。
