ServletDeployer (Vaadin Platform (vaadin-platform-javadoc) 23.5.5 API)

java.lang.Object
- com.vaadin.flow.server.startup.ServletDeployer

All Implemented Interfaces:

EventListener, javax.servlet.ServletContextListener
```
public class ServletDeployer
extends Object
implements javax.servlet.ServletContextListener
```
Context listener that automatically registers Vaadin servlets.
The servlets registered are:
- Vaadin application servlet, mapped to '/*'
  The servlet won't be registered, if any VaadinServlet is registered already or if there are no classes annotated with Route annotation.
- Static files servlet, mapped to '/VAADIN/static' responsible to resolve files placed in the '[webcontext]/VAADIN/static' folder or in the '[classpath]/META-INF/static' location. It prevents sensible files like 'stats.json' and 'flow-build-info.json' to be served. It manages cache headers based on the '.cache.' and '.nocache.' fragment in the file name.
In addition to the rules above, a servlet won't be registered, if any servlet had been mapped to the same path already or if InitParameters.DISABLE_AUTOMATIC_SERVLET_REGISTRATION system property is set to true.
For internal use only. May be renamed or removed in a future release.
