公司项目,开发语言为java,中间件为Tomcat,运行过程中,从Tomcat出现了一些异常,现将异常及解决办法记录如下,仅供参考。(不断在补充中.......)

异常一:

1、日志内容

org.apache.coyote.http11.AbstractHttp11Processor.process Error parsing HTTP request headerNote: 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 tokensat org.apache.coyote.http11.AbstractNioInputBuffer.parseRequestLine(AbstractNioInputBuffer.java:233)at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1017)at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:684)at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1520)at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.run(NioEndpoint.java:1476)at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145)at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61)at java.lang.Thread.run(Thread.java:745)

2、解决办法

在tomcat安装文件夹的 conf/catalina.properties 中最后添加一行:

org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true

2、解决办法

修改tomcat的bin目录下的catalina.sh文件,在# OS specific support. $var _must_ be set to either true or false.与cygwin=false之间加上JAVA_OPTS="-Ddruid.registerToSysProperty=true"

异常三:

1、日志内容

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。
