接口 RouterFunction<T extends ServerResponse>

方法详细资料

• route

  Optional<HandlerFunction<T>> route​(ServerRequest request)

  Return the handler function that matches the given request.

  参数:

  request - the request to route

  返回:

  an Optional describing the HandlerFunction that matches this request, or an empty Optional if there is no match

• and

  default RouterFunction<T> and​(RouterFunction<T> other)

  Return a composed routing function that first invokes this function, and then invokes the other function (of the same response type T) if this route had no result.

  参数:

  other - the function of type T to apply when this function has no result

  返回:

  a composed function that first routes with this function and then the other function if this function has no result

  andOther(RouterFunction)

• andOther

  default RouterFunction<?> andOther​(RouterFunction<?> other)

  Return a composed routing function that first invokes this function, and then invokes the other function (of a different response type) if this route had no result.

  参数:

  other - the function to apply when this function has no result

  返回:

  a composed function that first routes with this function and then the other function if this function has no result

• andRoute

  default RouterFunction<T> andRoute​(RequestPredicate predicate,
                                     HandlerFunction<T> handlerFunction)

  Return a composed routing function that routes to the given handler function if this route does not match and the given request predicate applies. This method is a convenient combination of and(RouterFunction) and RouterFunctions.route(RequestPredicate, HandlerFunction).

  参数:

  predicate - the predicate to test if this route does not match

  handlerFunction - the handler function to route to if this route does not match and the predicate applies

  返回:

  a composed function that route to handlerFunction if this route does not match and if predicate applies

• andNest

  default RouterFunction<T> andNest​(RequestPredicate predicate,
                                    RouterFunction<T> routerFunction)

  Return a composed routing function that routes to the given router function if this route does not match and the given request predicate applies. This method is a convenient combination of and(RouterFunction) and RouterFunctions.nest(RequestPredicate, RouterFunction).

  参数:

  predicate - the predicate to test if this route does not match

  routerFunction - the router function to route to if this route does not match and the predicate applies

  返回:

  a composed function that route to routerFunction if this route does not match and if predicate applies

• filter

  default <S extends ServerResponse> RouterFunction<S> filter​(HandlerFilterFunction<T,​S> filterFunction)

  Filter all handler functions routed by this function with the given filter function.

  类型参数:

  S - the filter return type

  参数:

  filterFunction - the filter to apply

  返回:

  the filtered routing function

• accept

  default void accept​(RouterFunctions.Visitor visitor)

  Accept the given visitor. Default implementation calls RouterFunctions.Visitor.unknown(RouterFunction); composed RouterFunction implementations are expected to call accept for all components that make up this router function.

  参数:

  visitor - the visitor to accept
