Spring Boot Tomcat Configuration

About the creation of the spring boot inline tomcat in

In the Onrefresh method of Embeddedwebapplicationcontext,

A servletcontextinitializer was added when it was created.

This.embeddedservletcontainer = Containerfactory
      . Getembeddedservletcontainer (Getselfinitializer ());

This servletcontextinitializer is used to add servlet,filter when Tomcat is started

In addition, there seems to be an interface that provides the configuration of Web. XML, but don't know how to use it, just remember

Springbootservletinitializer-"Webapplicationinitializer

Springservletcontainerinitializer-"Servletcontainerinitializer
