查看日志发现上面那一段.百度一下说是Tomcat的header缓冲区大小不够,需要在server.xml中增加maxHttpHeaderSize字段,设置一下.还有人说换一个版本的tomcat就可以了,我觉得那根本不是问题的原因好吧…..
下面一段是网上摘取的内容,测试一下是否可以解决问题:
//********************************************************************************************************************************************
<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"/>
tomcat常用配置注释：
maxHttpHeaderSize="8192" http请求头信息的最大程度，超过此长度的部分不予处理。一般8K。
URIEncoding="UTF-8" 指定Tomcat容器的URL编码格式。
disableUploadTimeout="true" 上传时是否使用超时机制
enableLookups="false"--是否反查域名，默认值为true。
为了提高处理能力，应设置为false compression="on" 打开压缩功能
compressionMinSize="10240" 启用压缩的输出内容大小，默认为2KB
noCompressionUserAgents="gozilla, traviata" 对于以下的浏览器，不启用压缩
compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain" 哪些资源类型需要压缩 tomcat配置示例： 配置示例
