I try to connect my Springboot(v1.4.2) App with a Hazelcast Cluster to find stored data. For that I'm using a hazelcast-client instance and I created a HazelcastRepository to search my data.

The problem is that my Repository doesn't find any data. It always returns an empty list when I test with findAll() or null when I test with findOne():

Below are my Service/Repository/Domain/Configuration codes:

@Service public class MyService { private static final Logger log = LoggerFactory.getLogger(MyService .class); private final MyHCRepository repository; @Autowired public MyService (final MyHCRepository repository) { this.repository = repository; } public String get(final String name) { List<Element> elements= repository.findByName(name); return elements.toString(); } } 

Here is my Repo and domain:

@Repository public interface MyHCRepository extends HazelcastRepository<Element, Integer> { List<Element> findByName(String name); } @Data @KeySpace public class Element implements Serializable { private Integer id; private String name; } 

Here is my hazelcast-client config:

@Configuration @EnableHazelcastRepositories public class HazelcastConfiguration { @Bean @Qualifier("client") public HazelcastInstance hazelcastClientInstance() { final ClientConfig clientConfig = new ClientConfig(); final ClientNetworkConfig networkConfig = new ClientNetworkConfig(); networkConfig.setAddresses(singletonList("127.0.0.1")); clientConfig.setNetworkConfig(networkConfig); return HazelcastClient.newHazelcastClient(clientConfig); } @Bean public KeyValueTemplate keyValueTemplate() { return new KeyValueTemplate(new HazelcastKeyValueAdapter(hazelcastClientInstance())); } } 

And in my pom, I use these dependencies:

<dependencies> <dependency> <groupId>com.hazelcast</groupId> <artifactId>hazelcast-client</artifactId> <version>3.6.6</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>com.hazelcast</groupId> <artifactId>spring-data-hazelcast</artifactId> <version>1.0</version> <exclusions> <exclusion> <artifactId>spring-data-keyvalue</artifactId> <groupId>org.springframework.data</groupId> </exclusion> <exclusion> <groupId>com.hazelcast</groupId> <artifactId>hazelcast</artifactId> </exclusion> </exclusions> </dependency> <dependency> <artifactId>spring-data-keyvalue</artifactId> <groupId>org.springframework.data</groupId> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> </dependencies> 

I got no errors, no exceptions. It's like there were no data in my Hazelcast cluster but I know there is. With my client if I connect and load a Map from the Hazelcast-Cluster like this:

client.getMap("mapsName"); 

then I got my Data but if I try to use the Hazelcast Repository, I dont find anything. Could someone tell me what's wrong?
