Examples with AllowedMethodsHandler io.undertow.server.handlers.AllowedMethodsHandler used on opensource projects

Example 1 with AllowedMethodsHandler

use of io.undertow.server.handlers.AllowedMethodsHandler in project adeptj-runtime by AdeptJ.

the class Server method rootHandler.

/**
 * Chaining of Undertow {@link HttpHandler} instances as follows.
 * <p>
 * 1. GracefulShutdownHandler
 * 2. RequestLimitingHandler
 * 3. AllowedMethodsHandler
 * 4. PredicateHandler which resolves to either RedirectHandler or SetHeadersHandler
 * 5. RequestBufferingHandler if request buffering is enabled, wrapped in SetHeadersHandler
 * 5. And Finally ServletInitialHandler
 *
 * @param servletInitialHandler the {@link io.undertow.servlet.handlers.ServletInitialHandler}
 * @return GracefulShutdownHandler as the root handler
