JpaPingingServletContextListener (JPA and guiced servlet integration 7.0-jakarta API)

java.lang.Object
- pl.morgwai.base.servlet.scopes.GuiceServletContextListener
- - pl.morgwai.base.servlet.guiced.jpa.JpaServletContextListener
  - - pl.morgwai.base.servlet.guiced.jpa.JpaPingingServletContextListener

All Implemented Interfaces:

ServletContextListener, EventListener
```
public abstract class JpaPingingServletContextListener
extends JpaServletContextListener
```
A JpaServletContextListener that automatically registers/deregisters endpoint instances to a WebsocketPingerService. Endpoints need to be created with addEndpoint(Class, String) or annotated to use JpaPingingServletContextListener.JpaPingingEndpointConfigurator.
