Tomcat常见异常及解决方案代码实例

本文主要介绍Tomcat常见异常及解决方案代码示例，通过示例代码介绍的非常详细，对大家的学习或工作有一定的参考价值，有需要的朋友可以参考一下。

公司的开发语言是java，中间件是Tomcat。在 *** 作过程中，Tomcat出现了一些异常。异常情况及解决方法记录如下，仅供参考。(不断补充......)

异常1:

1.日志内容

org.Apache.coyote.http11.abstractHttp11processor.process解析HTTP请求头时出错
注意:以后出现的HTTP头解析错误将在调试级别记录。
Java.lang.illegalargumentexception:在方法名中发现无效字符。HTTP方法名必须是org.Apache.coyote.HTTP11.abstractnioinputbuffer.parserequestline(abstractnioinputbuffer.Java:233)
。

2.解决办法

在tomcat安装文件夹的conf/catalina.properties中添加最后一行:

org.Apache.Tomcat.util.buf.udecoder.allow_ENCODED_SLASH=true

2.解决办法

修改tomcat的bin目录中的catalina.sh文件，并在#osspecificsupport之间添加Java_opts="-DDRuid.registertosysproperty=true"。$var_must_设置为true或false。而cygwin=false。
