公司項(xiàng)目，開發(fā)語言為java，中間件為Tomcat，運(yùn)行過程中，從Tomcat出現(xiàn)了一些異常，現(xiàn)將異常及解決辦法記錄如下，僅供參考。（不斷在補(bǔ)充中.......）
異常一：
1、日志內(nèi)容
org.apache.coyote.http11.AbstractHttp11Processor.process Error parsing HTTP request header
Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.
java.lang.IllegalArgumentException: Invalid character found in method name. HTTP method names must be tokens

at java.lang.Thread.run(Thread.java:745)
2、解決辦法
在tomcat安裝文件夾的 conf/catalina.properties 中最后添加一行：
org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true
異常二：

2、解決辦法
修改tomcat的bin目錄下的catalina.sh文件，在# OS specific support. $var _must_ be set to either true or false.與cygwin=false之間加上JAVA_OPTS="-Ddruid.registerToSysProperty=true"
異常三：
1、日志內(nèi)容
INFO [http-nio-80-exec-16] org.apache.coyote.http11.AbstractHttp11Processor.process Error parsing HTTP request header
Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.

at java.lang.Thread.run(Thread.java:745)
2、解決辦法
修改tomcat安裝文件夾的 conf/server.xml，在 <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" maxHttpHeaderSize ="10240" redirectPort="8443" />中，maxHttpHeaderSize的默認(rèn)值是8*1024，你只需要調(diào)成你需要的值就好了。
以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
