公司項目，開發(fā)語言為java，中間件為tomcat，運行過程中，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。（不斷在補充中…….）
異常一：
1、日志內容
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
