我尝试将我的Springboot(v1.4.2)应用程序与Hazelcast Cluster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。
问题是我的存储库找不到任何数据。当我使用findAll()进行测试时,它总是返回一个空列表;当我使用findOne()进行测试时,它总是返回null:
以下是我的服务/存储库/域/配置代码:
public void checkMatchingEmojis() {
final Pattern pattern = Pattern.compile(sEmojiRegex);
final Matcher matcher = pattern.matcher(sEmojiTest);
int foundEmojiCount = 0;
while (matcher.find()) {
System.out.println("Full match: " + matcher.group(0));
foundEmojiCount++;
}
System.out.println("*******************************************");
System.out.println("Input Emoji count = 1627");
System.out.println("Captured Emoji count = " + foundEmojiCount);
System.out.println("*******************************************");
}
这是我的回购和域名:
@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();
}
}
这是我的hazelcast-client配置:
@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;
}
在我的pom中,我使用了这些依赖项:
@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()));
}
}
我没有错误,没有例外。这就像我的Hazelcast集群中没有数据,但我知道有。如果我连接并从Hazelcast-Cluster加载地图,请使用我的客户端:
<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>

<dependency>

<groupId>org.springframework.data</groupId>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</dependency>
</dependencies>
然后我得到了我的数据但是如果我尝试使用Hazelcast存储库,我什么都找不到。 有人能告诉我什么是错的吗?
答案 0 :(得分:1)
一切都很好,我发现了问题。我只需要将我的Map的名称与我的Domain类(Element)中的@Keyspace Annotation相关联 - &gt; @Keyspace(&#34; myMapName&#34)
