Method Details

supports

public boolean supports(Object handler)

specified by:

supports in interface HandlerAdapter

Parameters:

handler - the handler object to check

handle

public&nbsp;Mono<HandlerResult>&nbsp;handle(serverWebExchange&nbsp;exchange,
 Object&nbsp;handler)

Description copied from interface: HandlerAdapter

Handle the request with the given handler, previously checked via HandlerAdapter.supports(Object).

Implementations should consider the following for exception handling:

• Handle invocation exceptions within this method.
• set an exception handler on the returned HandlerResult to handle deferred exceptions from asynchronous return values, and to handle exceptions from response rendering.
• Implement DispatchExceptionHandler to extend exception handling to exceptions that occur before a handler is selected.

specified by:

handle in interface HandlerAdapter

Parameters:

exchange - current server exchange

handler - the selected handler which must have been previously checked via HandlerAdapter.supports(Object)

Returns:

Mono that emits a HandlerResult, or completes empty if the request is fully handled; any error signal would not be handled within the DispatcherHandler, and would instead be processed by the chain of registered WebExceptionHandlers at the end of the WebFilter chain
