Examples with ServerBuilder io.grpc.ServerBuilder used on opensource projects

Example 1 with ServerBuilder

use of io.grpc.ServerBuilder in project h2o-3 by h2oai.

the class GrpcExtension method onLocalNodeStarted.

@Override
public void onLocalNodeStarted() {
    if (grpcPort != 0) {
        ServerBuilder sb = ServerBuilder.forPort(grpcPort);
        RegisterGrpcApi.registerWithServer(sb);
        netty = sb.build();
        try {
            netty.start();
            Log.info("Started GRPC server on localhost:" + grpcPort);
        } catch (IOException e) {
            netty = null;
            throw new RuntimeException("Failed to start the GRPC server on port " + grpcPort, e);
        }
        Runtime.getRuntime().addShutdownHook(new Thread() {

            @Override
            public void run() {
                if (netty != null) {
                    // Use stderr here since the logger may have been reset by its JVM shutdown hook.
                    System.err.println("*** shutting down gRPC server since JVM is shutting down");
                    netty.shutdown();
                    System.err.println("*** server shut down");
                }
            }
        });
    }
}

Example 2 with ServerBuilder

use of io.grpc.ServerBuilder in project dubbo by alibaba.

the class GrpcOptionsUtils method buildServerBuilder.

static ServerBuilder buildServerBuilder(URL url, NettyServerBuilder builder) {
    int maxInboundMessageSize = url.getParameter(MAX_INBOUND_MESSAGE_SIZE, 0);
    if (maxInboundMessageSize > 0) {

    }
    int maxCalls = url.getParameter(MAX_CONCURRENT_CALLS_PER_CONNECTION, url.getParameter(EXECUTES_KEY, 0));
    if (maxCalls > 0) {
        builder.maxConcurrentCallsPerConnection(maxCalls);
    }
    // server interceptors
    List<ServerInterceptor> serverInterceptors = ExtensionLoader.getExtensionLoader(ServerInterceptor.class).getActivateExtension(url, SERVER_INTERCEPTORS, PROVIDER_SIDE);
    for (ServerInterceptor serverInterceptor : serverInterceptors) {
        builder.intercept(serverInterceptor);
    }
    // server filters
    List<ServerTransportFilter> transportFilters = ExtensionLoader.getExtensionLoader(ServerTransportFilter.class).getActivateExtension(url, TRANSPORT_FILTERS, PROVIDER_SIDE);
    for (ServerTransportFilter transportFilter : transportFilters) {
        builder.addTransportFilter(transportFilter.grpcTransportFilter());
    }
    String thread = url.getParameter(EXECUTOR, url.getParameter(DISPATCHER_KEY));
    if ("direct".equals(thread)) {
        builder.directExecutor();
    } else {
        builder.executor(ExtensionLoader.getExtensionLoader(ThreadPool.class).getAdaptiveExtension().getExecutor(url));
    }
    // Give users the chance to customize ServerBuilder
    return getConfigurator().map(configurator -> configurator.configureServerBuilder(builder, url)).orElse(builder);
