- org.springframework.web.server.adapter.AbstractReactiveWebInitializer

All Implemented Interfaces:
WebApplicationInitializer
```
public abstract class AbstractReactiveWebInitializer
extends Object
implements WebApplicationInitializer
```
Base class for a WebApplicationInitializer that installs a Spring Reactive Web Application on a Servlet container.
Spring configuration is loaded and given to WebHttpHandlerBuilder which scans the context looking for specific beans and creates a reactive HttpHandler. The resulting handler is installed as a Servlet through the ServletHttpHandlerAdapter.
