Interface ServerBuilder

public interface ServerBuilder

Builder API to create server bindings.

Use Http.newServerAt() to create a builder, use methods to customize settings, and then call one of the bind* methods to bind a server.

java.util.concurrent.CompletionStage<ServerBinding>	bind(HandlerProvider handlerProvider) Bind a new HTTP server and use the given handler provider to create an asynchronous handler pekko.stream.javadsl.Flow for processing all incoming connections.
java.util.concurrent.CompletionStage<ServerBinding>	bindFlow(org.apache.pekko.stream.javadsl.Flow<HttpRequest,HttpResponse,?> handlerFlow) Binds a new HTTP server at the given endpoint and uses the given handler pekko.stream.scaladsl.Flow for processing all incoming connections.

ServerBuilder	enableHttps(HttpsConnectionContext context) Enable HTTPS for this binding with the given context.
ServerBuilder	logTo(org.apache.pekko.event.LoggingAdapter log) Use a custom logger

Method Detail

onInterface

ServerBuilder onInterface(java.lang.String interface_)

Change interface to bind to

onPort

ServerBuilder onPort(int port)

Change port to bind to

logTo

ServerBuilder logTo(org.apache.pekko.event.LoggingAdapter log)

Use a custom logger

withSettings

ServerBuilder withSettings(ServerSettings settings)

Use custom ServerSettings for the binding.

Parameters:

settings - (undocumented)

Returns:

(undocumented)

adaptSettings

ServerBuilder adaptSettings(org.apache.pekko.japi.function.Function<ServerSettings,ServerSettings> f)

Adapt the current configured settings with a function.

Parameters:

f - (undocumented)

Returns:

(undocumented)

enableHttps

ServerBuilder enableHttps(HttpsConnectionContext context)

Enable HTTPS for this binding with the given context.

Parameters:

context - (undocumented)

Returns:

(undocumented)

withMaterializer

ServerBuilder withMaterializer(org.apache.pekko.stream.Materializer materializer)

Use custom Materializer for the binding

Parameters:

materializer - (undocumented)

Returns:

(undocumented)

bind

java.util.concurrent.CompletionStage<ServerBinding> bind(org.apache.pekko.japi.function.Function<HttpRequest,java.util.concurrent.CompletionStage<HttpResponse>> f)

Bind a new HTTP server and use the given asynchronous handler pekko.stream.javadsl.Flow for processing all incoming connections.

The number of concurrently accepted connections can be configured by overriding the pekko.http.server.max-connections setting. Please see the documentation in the reference.conf for more information about what kind of guarantees to expect.

Supports HTTP/2 on the same port if http2 support is enabled.

Parameters:

f - (undocumented)

Returns:

(undocumented)

bind

java.util.concurrent.CompletionStage<ServerBinding> bind(HandlerProvider handlerProvider)

Bind a new HTTP server and use the given handler provider to create an asynchronous handler pekko.stream.javadsl.Flow for processing all incoming connections.

Most importantly, you can pass a Route to this method because Route implements HandlerProvider.

The number of concurrently accepted connections can be configured by overriding the pekko.http.server.max-connections setting. Please see the documentation in the reference.conf for more information about what kind of guarantees to expect.

Supports HTTP/2 on the same port if http2 support is enabled.

Parameters:

handlerProvider - (undocumented)

Returns:

(undocumented)

bindSync

java.util.concurrent.CompletionStage<ServerBinding> bindSync(org.apache.pekko.japi.function.Function<HttpRequest,HttpResponse> f)

Bind a new HTTP server at the given endpoint and uses the given handler pekko.stream.javadsl.Flow for processing all incoming connections.

The number of concurrently accepted connections can be configured by overriding the pekko.http.server.max-connections setting. Please see the documentation in the reference.conf for more information about what kind of guarantees to expect.

Supports HTTP/2 on the same port if http2 support is enabled.

Parameters:

f - (undocumented)

Returns:

(undocumented)

bindFlow

java.util.concurrent.CompletionStage<ServerBinding> bindFlow(org.apache.pekko.stream.javadsl.Flow<HttpRequest,HttpResponse,?> handlerFlow)

Binds a new HTTP server at the given endpoint and uses the given handler pekko.stream.scaladsl.Flow for processing all incoming connections.

The number of concurrently accepted connections can be configured by overriding the pekko.http.server.max-connections setting. Please see the documentation in the reference.conf for more information about what kind of guarantees to expect.

Parameters:

handlerFlow - (undocumented)

Returns:

(undocumented)

connectionSource

org.apache.pekko.stream.javadsl.Source<IncomingConnection,java.util.concurrent.CompletionStage<ServerBinding>> connectionSource()

Creates a pekko.stream.javadsl.Source of pekko.http.javadsl.IncomingConnection instances which represents a prospective HTTP server binding on the given endpoint.

Note that each materialization will create a new binding, so

* if the configured port is 0 the resulting source can be materialized several times. Each materialization will then be assigned a new local port by the operating system, which can then be retrieved by the materialized pekko.http.javadsl.ServerBinding.

* if the configured port is non-zero subsequent materialization attempts of the produced source will immediately fail, unless the first materialization has already been unbound. Unbinding can be triggered via the materialized pekko.http.javadsl.ServerBinding.

Returns:

(undocumented)
