I try to connect my Springboot(v1.5.4) 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 when I start my app, I always got this Spring error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myHCRepository': Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to avoid type ambiguities)
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(); } }
@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; }
@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 KeyValueOperations keyValueTemplate() { return new KeyValueTemplate(hazelcastKeyValueAdapter()); } @Bean public HazelcastKeyValueAdapter hazelcastKeyValueAdapter() { return new HazelcastKeyValueAdapter(); } } And in my pom, I use these dependencies:
<dependency> <groupId>com.hazelcast</groupId> <artifactId>hazelcast-client</artifactId> </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>1.1</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> When I start my Springboot App, I got always this Exception:
