我尝试将我的Springboot（v1.5.4）应用程序与Hazelcast群集连接以查找存储的数据。 为此，我使用了hazelcast-client实例，并创建了一个HazelcastRepository来搜索我的数据。
问题在于，当我启动应用程序时，我总是遇到Spring错误：
org.springframework.beans.factory.BeanCreationException：创建名为'myHCRepository'的bean时出错：无法解析匹配的构造函数（提示：为简单参数指定索引/类型/名称参数以避免类型歧义）
以下是我的服务/存储库/域/配置代码：
@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();
}
}
在我的pom中，我使用了这些依赖项：
<dependency>
<groupId>com.hazelcast</groupId>
<artifactId>hazelcast-client</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>

<artifactId>spring-data-hazelcast</artifactId>
<version>1.1</version>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</dependency>
当我启动Springboot应用程序时，我总是得到这个例外：

有人能告诉我这个错误是什么意思吗？以及如何解决它？
答案 0 :(得分：1)
检查 spring-data-commons 和 spring-data-keyvalue 的依赖版本
尝试
org.springframework.data:spring-data-commons:1.12.5.RELEASE
和
org.springframework.data:spring-data-keyvalue:1.1.5.RELEASE
