Examples with DefaultFailureHandler org.eclipse.hono.service.http.DefaultFailureHandler used on opensource projects

Example 1 with DefaultFailureHandler

use of org.eclipse.hono.service.http.DefaultFailureHandler in project hono by eclipse.

the class DelegatingDeviceManagementHttpEndpointTest method setUp.

/**
 * Sets up the fixture.
 */
@SuppressWarnings("unchecked")
@BeforeEach
public void setUp() {
    final Vertx vertx = mock(Vertx.class);
    router = Router.router(vertx);
    // make sure that ServiceInvocationExceptions are properly handled
    // and result in the exception's error code being set on the response
    router.route().failureHandler(new DefaultFailureHandler());
    service = mock(DeviceManagementService.class);
    when(service.searchDevices(anyString(), anyInt(), anyInt(), any(List.class), any(List.class), any(Span.class))).thenReturn(Future.succeededFuture(OperationResult.empty(HttpURLConnection.HTTP_OK)));
    final var endpoint = new DelegatingDeviceManagementHttpEndpoint<>(vertx, service);
    endpoint.setConfiguration(new ServiceConfigProperties());
    endpoint.addRoutes(router);
    requestBody = Buffer.buffer();
    requestParams = MultiMap.caseInsensitiveMultiMap();
    requestHeaders = MultiMap.caseInsensitiveMultiMap();
}

Example 2 with DefaultFailureHandler

use of org.eclipse.hono.service.http.DefaultFailureHandler in project hono by eclipse.

the class AbstractVertxBasedHttpProtocolAdapter method createRouter.

/**
 * Creates the router for handling requests.
 * <p>
 * This method creates a router instance along with a route matching all request. That route is initialized with the
 * following handlers and failure handlers:
 * <ol>
 * <li>a handler to add a Micrometer {@code Timer.Sample} to the routing context,</li>
 * <li>a handler and failure handler that creates tracing data for all server requests,</li>
 * <li>a handler to log when the connection is closed prematurely,</li>
 * <li>a default failure handler,</li>
 * <li>a handler limiting the body size of requests to the maximum payload size set in the <em>config</em>
 * properties.</li>
 * </ol>
 *
 * @return The newly created router (never {@code null}).
