tomcat8 运行期错误HTTP header parsing errors

 

添加头部信息后，开发阶段没异常，部署到tomcat中调用时出现错误：

07-Dec-2016 16:03:57.210 信息 [http-nio-8080-exec-5] org.apache.coyote.http11.Http11Processor.service Error parsing HTTP request header
 Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.

需要在tomcat的server.xml中配置：

maxHttpHeaderSize="8192" 

 

上面这行配置在这里：

    <Connector port="8080" protocol="HTTP/1.1"
			   maxHttpHeaderSize="8192" 
                           connectionTimeout="20000"
			   maxThreads="150"
			   maxSpareThreads="75"
               redirectPort="8443" />
