HazelcastInstance не вызывается с помощью Spring Bean

Я пытаюсь использовать встроенный Hazelcast в приложении Spring MVC REST.Мой файл pom:

Мой класс конфигурации Spring для экземпляра Hazelcast (сервер): 

@Configuration
@EnableCaching
public class HazelcastConfig {
    @Bean
    public Config config() {
        Config config = new Config();
        config.getNetworkConfig().getJoin().getTcpIpConfig().setEnabled(true);
        config.getNetworkConfig().getJoin().getMulticastConfig().setEnabled(false);
        config.getNetworkConfig().getJoin().getTcpIpConfig().addMember("127.0.0.1:5701");
        return config;
    }

    @Bean
    public HazelcastInstance hazelcastInstance(final Config config) {
        return Hazelcast.getOrCreateHazelcastInstance(config);
    }
}

И моя конфигурация Spring для клиента Hazelcast: 

@Configuration
@EnableCaching
public class CachingConfiguration extends CachingConfigurerSupport {
    @Bean
    public CacheManager cacheManager() {
        ClientConfig config = new ClientConfig();
        config.getNetworkConfig().addAddress("127.0.0.1:5701");
        HazelcastInstance hInstance = HazelcastClient.newHazelcastClient(config);
        return new HazelcastCacheManager(hInstance);
    }

    @Bean
    public KeyGenerator keyGenerator() {
        return null;
    }
}

Когда я запускаю это приложение Sping MVC, появляется следующая ошибка:

Как вы видите, клиент Hazelcast запускается, но сервер Hazelcast вообще не вызывается.Таким образом, клиент hazelcast выдает ошибку, говоря, что он не может подключиться.Что-то не так с конфигурацией Spring?

Когда вы встраиваете Hazelcast, вам не нужно запускать отдельный клиент Hazelcast в той же JVM.Когда программа запускается, какая гарантия у вас, что сервер hazelcast запускается до Hazelcastclient?Просматривая ваши логи, клиент Hazelcast запускается средой Spring и не может найти сервер Hazelcast.

У вас есть 2 варианта

  1. Запустите удаленный сервер Hazelcast и позвольте Hazelcastclient, встроенному в MVC, подключиться к нему.
  2. Запускать сервер Hazelcast, встроенный только в ваше приложение MVC

Совершенно очевидно, что вы неправильно настроили Hazelcast, глядя на исключение.Любой экземпляр hazelcast уже работает в 127.0.0.1:5701?Я бы посоветовал прочитать документацию Hazelcast, чтобы узнать, как правильно его настроить в зависимости от ваших потребностей.

Кстати, вы использовали HazelcastInstance как клиент и сервер, если вы встраивали Hazelcast в свое приложение.Клиент нужен только при подключении к внешнему кластеру Hazelcast.
