Today, when I used springboot to develop my blog system, the following exception always appeared when I click Submit markdown file in the browser:
java.lang.IllegalArgumentException: Request header is too largeThe web technology stack used is springboot, with Tomcat service embedded
Solution
After troubleshooting, it is because the server has a request length configuration. You can see from the source code of the server configuration class serverproperties that there are the following parameters:
/**
* Maximum size, in bytes, of the HTTP message header.
*/
private int maxHttpHeaderSize = 0; // bytesThere is a HTTP header maximum value setting, the unit is byte, as long as the application.properties The maximum value of file configuration is enough
#Request header length limit
server.max-http-header-size=10000000Read More:
