- org.springframework.web.reactive.DispatcherHandler

所有已实现的接口:
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.

  - DispatcherHandler
```
public DispatcherHandler()
```
    Create a new DispatcherHandler which needs to be configured with an ApplicationContext through setApplicationContext(org.springframework.context.ApplicationContext).
  - DispatcherHandler
```
public DispatcherHandler(ApplicationContext applicationContext)
```
    Create a new DispatcherHandler for the given ApplicationContext.
    参数:
    applicationContext - the application context to find the handler beans in
- 方法详细资料
  - 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).
    返回:
    immutable list with the configured mappings or null
  - setApplicationContext
```
public void setApplicationContext(ApplicationContext applicationContext)
```
    从接口复制的说明: 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.
    指定者:
    setApplicationContext 在接口中 ApplicationContextAware
    参数:
    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)
```
    从接口复制的说明: WebHandler
    Handle the web server exchange.
    指定者:
    handle 在接口中 WebHandler
    参数:
    exchange - the current server exchange
    返回:
    Mono<Void> to indicate when request handling is complete
