What is the difference between jetty and tomcat?

Course Introduction：Differences: 1. The Jetty architecture is implemented based on Handler, and the main extension functions can be implemented using Handler. The expansion is simple; the Tomcat architecture is designed based on containers. To expand, you need to understand the overall design structure of Tomcat, which is not easy to expand. 2.
