- org.springframework.web.reactive.DispatcherHandler

All Implemented Interfaces:
Aware, ApplicationContextAware, WebHandler
```
public class DispatcherHandler
extends Object
implements WebHandler, ApplicationContextAware
```
Central dispatcher for HTTP request handlers/controllers. Dispatches to registered handlers for processing a request, providing convenient mapping facilities.
DispatcherHandler discovers the delegate components it needs from Spring configuration. It detects the following in the application context:
- HandlerMapping -- map requests to handler objects
- HandlerAdapter -- for using any handler interface
- HandlerResultHandler -- process handler return values
DispatcherHandler is also designed to be a Spring bean itself and implements ApplicationContextAware for access to the context it runs in. If DispatcherHandler is declared with the bean name "webHandler" it is discovered by WebHttpHandlerBuilder.applicationContext which creates a processing chain together with WebFilter, WebExceptionHandler and others.
A DispatcherHandler bean declaration is included in @EnableWebFlux configuration.
Since:
5.0

  - DispatcherHandler
```
public DispatcherHandler(ApplicationContext applicationContext)
```
    Create a new DispatcherHandler for the given ApplicationContext.
    Parameters:
    applicationContext - the application context to find the handler beans in

  - getHandlerMappings
```
@Nullable
public final List<HandlerMapping> getHandlerMappings()
```
    Return all HandlerMapping beans detected by type in the injected context and also sorted.
    Note: This method may return null if invoked prior to setApplicationContext(ApplicationContext).
    Returns:
    immutable list with the configured mappings or null
  - setApplicationContext
```
public void setApplicationContext(ApplicationContext applicationContext)
```
    Description copied from interface: ApplicationContextAware
    Set the ApplicationContext that this object runs in. Normally this call will be used to initialize the object.
    Invoked after population of normal bean properties but before an init callback such as InitializingBean.afterPropertiesSet() or a custom init-method. Invoked after ResourceLoaderAware.setResourceLoader(org.springframework.core.io.ResourceLoader), ApplicationEventPublisherAware.setApplicationEventPublisher(org.springframework.context.ApplicationEventPublisher) and MessageSourceAware, if applicable.
    Specified by:
    setApplicationContext in interface ApplicationContextAware
    Parameters:
    applicationContext - the ApplicationContext object to be used by this object

  - initStrategies
```
protected void initStrategies(ApplicationContext context)
```
  - handle
```
public reactor.core.publisher.Mono<Void> handle(ServerWebExchange exchange)
```
    Description copied from interface: WebHandler
    Handle the web server exchange.
    Specified by:
    handle in interface WebHandler
    Parameters:
    exchange - the current server exchange
    Returns:
    Mono<Void> to indicate when request handling is complete
