How to configure AJP connector in the embedded tomcat?

Question

I need to configure AJP connector in embedded tomcat https://tomcat.apache.org/tomcat-8.0-doc/config/ajp.html Equals to the following configuration:

<Connector port="8009" protocol="AJP/1.3" redirectPort="8080" />

How to do it?

Answer 1

// initialize tomcat with default nio connector
Tomcat tomcat = new Tomcat();
tomcat.setPort(8080);
tomcat.getHost().setAppBase(".");
tomcat.addWebapp("/", ".");

// create an AJP connector
Connector ajpConnector = new Connector("AJP/1.3");
ajpConnector.setPort(8009);
ajpConnector.setRedirectPort(8080);
ajpConnector.setSecure(false);

// add connector to tomcat
tomcat.getService().addConnector(ajpConnector);
tomcat.start();
tomcat.getServer().await();

From the startup logs:

http-nio is listening on port 8080 and ajp-nio on port 8009.
