Usage

Create a Service Exporter bean in the context of the service you want to expose

@Bean
public GrpcInvokerServiceExporter userServiceServer() {
    GrpcInvokerServiceExporter grpcInvokerServiceExporter = new GrpcInvokerServiceExporter();
    grpcInvokerServiceExporter.setServiceInterface(UserService.class);
    grpcInvokerServiceExporter.setService(userService());
    grpcInvokerServiceExporter.setPort(8888);
    return grpcInvokerServiceExporter;
}

Create a Proxy of the service on the client end

@Bean
public UserService userServiceClient() throws Exception {
    return (UserService) grpcInvokerProxyFactoryBean().getObject();
}

@Bean
public GrpcInvokerProxyFactoryBean grpcInvokerProxyFactoryBean() {
    GrpcInvokerProxyFactoryBean grpcInvokerProxyFactoryBean = new GrpcInvokerProxyFactoryBean();
    grpcInvokerProxyFactoryBean.setServiceUrl("localhost:8888");
    grpcInvokerProxyFactoryBean.setServiceInterface(UserService.class);
    return grpcInvokerProxyFactoryBean;
}
