Class TLSCertificateReloadListener

java.lang.Object

org.apache.catalina.security.TLSCertificateReloadListener

All Implemented Interfaces:

LifecycleListener

public class TLSCertificateReloadListener
extends Object
implements LifecycleListener

A LifecycleListener that may be used to monitor the expiration dates of TLS certificates and trigger automatic reloading of the TLS configuration a set number of days before the TLS certificate expires.

This listener assumes there is some other process (certbot, cloud infrastructure, etc) that renews the certificate on a regular basis and replaces the current certificate with the new one.

This listener does NOT re-read the Tomcat configuration from server.xml. If you make changes to server.xml you must restart the Tomcat process to pick up those changes.
