[FIXED] Programmatically obtain Embedded Servlet Container Information

Issue

I have a Spring Boot application. I want to display the current Servlet Container name and version in an Admin Console page.

Currently my application uses Tomcat, but I want to automatically display the same information if I were to, say, change to Jetty or some other embedded servlet container.

This information is not available (at least it seems) through the Environment, or Actuator endpoints.

How can I programmatically obtain the embedded servlet container name and version?

Solution

You can get the information you are looking for from the ServletContext.

You can autowire it with:

@Autowired ServletContext context;

and then access the wanted information:

context.getServerInfo()

In my Spring Boot application with an embedded Tomcat, I obtain the following string:

Apache Tomcat/8.5.27
