Package ch.rswk.meta.engine

Class HttpService

java.lang.Object

com.google.common.util.concurrent.AbstractExecutionThreadService

ch.rswk.meta.engine.AbstractEngineExecutionThreadService<HttpService.HttpServiceConfig>

ch.rswk.meta.engine.HttpService

All Implemented Interfaces:

EngineServices.ConfigurableService<HttpService.HttpServiceConfig>, EngineServices.InfoProvidingService, com.google.common.util.concurrent.Service

@Singleton
public class HttpService
extends AbstractEngineExecutionThreadService<HttpService.HttpServiceConfig>

HttpService uses a embedded Jetty Server with secure defaults and configuration options for TLS, Caching, CORS, CSP, exclude-/include access lists and more.

Custom HttpService.FilterConfig, HttpService.ServletConfig can be injected. HttpService.JerseyConfig can be used to inject REST-like API resources using Jersey.
