Spring boot@Autowire HazelcastInstance不带xml或yaml

Question

我试图在没有xml/yaml文件的情况下使用Spring Boot运行Hazelcast客户端应用程序，但我找不到通过Spring管理我的Hazelcast实例的方法。这是我的代码：

@Configuration
public class ConfigurationClass {

    @Autowired
    private Environment env;

    @Bean
    public ClientConfig clientConfig() {
        ClientConfig clientConfig = new ClientConfig();
        ClientNetworkConfig networkConfig = clientConfig.getNetworkConfig();
        networkConfig.addAddress("127.0.0.1:5701").setSmartRouting(true).addOutboundPortDefinition("34700-34710").setRedoOperation(true).setConnectionTimeout(5000);

        return clientConfig;

    }

    @Bean
    public HazelcastInstance hazelcastInstance(ClientConfig clientConfig) {
        return HazelcastClient.newHazelcastClient(clientConfig);
    }
}

当我尝试将hazelcast实例自动关联到主类时，我得到NULL

主要类别代码：

public class HazelcastServer implements Serializable {

    private static final long serialVersionUID = -1798311083790835361L;

    @Autowired
    private static HazelcastInstance hazelcastInstance;

    public static void main(String[] args) {
  System.out.println("hazelcastInstance: " + hazelcastInstance);
 }
}

您需要使用CommandLineRunner，以便Spring构建您的上下文（换句话说，创建@Bean并自动连接它们）

请参见此处的教程，以获得良好的开端：

https://spring.io/guides/gs/spring-boot/

基本上，您需要执行以下操作，而不是公共静态void main：

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public CommandLineRunner commandLineRunner(ApplicationContext ctx) {
        return args -> {

            System.out.println("Let's inspect the beans provided by Spring Boot:");

            String[] beanNames = ctx.getBeanDefinitionNames();
            Arrays.sort(beanNames);
            for (String beanName : beanNames) {
                System.out.println(beanName);
            }

        };
    }

}

@SpringBootApplication和SpringApplication。运行part告诉Spring它的神奇之处，阅读我链接的教程了解详细信息。
