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

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

	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 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。
