Servlet package import and servlet Import

Today, when I was learning Servlet and then creating a new servlet, the tutorial said: inherit an HttpServlet class and cannot find it.

Then search a bit, found that this class is in tomcat, to the tomcat directory lib under the servlet-api.jar package for reference;

How to reference it?

My solution is as follows: Right-click the project root directory, select Property, find Libraries in JAVA Build Path, and select Add extends JARs, find the servlet-api.jar package under lib in the tomcat directory, OK!

Then you can.

This is the current solution. I will know more about it later.
