查看日志發現上面那一段.百度一下說是Tomcat的header緩沖區大小不夠,需要在server.xml中增加maxHttpHeaderSize字段,設置一下.還有人說換一個版本的tomcat就可以了,我覺得那根本不是問題的原因好吧…..
下面一段是網上摘取的內容,測試一下是否可以解決問題:
//********************************************************************************************************************************************
<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常用配置注釋：
maxHttpHeaderSize="8192" http請求頭信息的最大程度，超過此長度的部分不予處理。一般8K。
URIEncoding="UTF-8" 指定Tomcat容器的URL編碼格式。
disableUploadTimeout="true" 上傳時是否使用超時機制
enableLookups="false"--是否反查域名，默認值為true。
為了提高處理能力，應設置為false compression="on" 打開壓縮功能
compressionMinSize="10240" 啟用壓縮的輸出內容大小，默認為2KB
noCompressionUserAgents="gozilla, traviata" 對於以下的瀏覽器，不啟用壓縮
compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain" 哪些資源類型需要壓縮 tomcat配置示例： 配置示例
