TomcatEmbeddedServletContainerFactory is missing in Spring Boot 2

I have Spring Boot application version 1.5.x, which uses org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory, I'm trying to migrate it to Spring Boot 2, but the app does not compile, although a have a dependency to org.springframework.boot:spring-boot-starter-tomcat. The compiler issues the error below:

error: package org.springframework.boot.context.embedded.tomcat

In Spring boot 2.0.0.RELEASE you can replace with following code::

@Bean
public ServletWebServerFactory servletContainer() {
    TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
        @Override
        protected void postProcessContext(Context context) {
            SecurityConstraint securityConstraint = new SecurityConstraint();
            securityConstraint.setUserConstraint("CONFIDENTIAL");
            SecurityCollection collection = new SecurityCollection();
            collection.addPattern("/*");
            securityConstraint.addCollection(collection);
            context.addConstraint(securityConstraint);
        }
    };
    tomcat.addAdditionalTomcatConnectors(redirectConnector());
    return tomcat;
}

private Connector redirectConnector() {
	Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
	connector.setScheme("http");
	connector.setPort(8080);
	connector.setSecure(false);
	connector.setRedirectPort(8443);
	return connector;
}

The class has been removed and replaced by org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory For more info check: Spring-Boot-2.0-Migration-Guide, which says:

> In order to support reactive use cases, the embedded containers > package structure has been refactored quite extensively. > EmbeddedServletContainer has been renamed to WebServer and the > org.springframework.boot.context.embedded package has been relocated > to org.springframework.boot.web.server.

I had the problem that I needed to sent bigger request, then the default size allowed:

@Bean
    public TomcatServletWebServerFactory containerFactory() {
        return new TomcatServletWebServerFactory() {
            protected void customizeConnector(Connector connector) {
                int maxSize = 50000000;
                super.customizeConnector(connector);
                connector.setMaxPostSize(maxSize);
                connector.setMaxSavePostSize(maxSize);
                if (connector.getProtocolHandler() instanceof AbstractHttp11Protocol) {

                    ((AbstractHttp11Protocol <?>) connector.getProtocolHandler()).setMaxSwallowSize(maxSize);
                    logger.info("Set MaxSwallowSize "+ maxSize);
                }
            }
        };

    }

Great Thx! I came from this article: https://blog.swdev.ed.ac.uk/2015/06/24/adding-embedded-tomcat-ajp-support-to-a-spring-boot-application/

using spring boot 2.1.3:

@Configuration
@Data
public class TomcatConfiguration {

@Value("${tomcat.ajp.port}")
int ajpPort;

@Value("${tomcat.ajp.remoteauthentication}")
String remoteAuthentication;

@Value("${tomcat.ajp.enabled}")
boolean tomcatAjpEnabled;

@Bean
public TomcatServletWebServerFactory servletContainer() {

    TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
    if (tomcatAjpEnabled)
    {
        Connector ajpConnector = new Connector("AJP/1.3");
        ajpConnector.setPort(ajpPort);
        ajpConnector.setSecure(false);
        ajpConnector.setAllowTrace(false);
        ajpConnector.setScheme("https");
        tomcat.addAdditionalTomcatConnectors(ajpConnector);
    }

    return tomcat;
  }

}
