Spring Data Hazelcast

Welcome to Spring Data Hazelcast project!

The primary goal of the Spring Data project is to make it easier to build Spring-powered applications that use new data access technologies. This module provides integration with Hazelcast.

Examples

For examples on using Spring Data Hazelcast, see dedicated Code Samples: spring-data-hazelcast-chemistry-sample and spring-data-jpa-hazelcast-migration.

Artifacts

Maven

<dependency>
    <groupId>com.hazelcast</groupId>
    <artifactId>spring-data-hazelcast</artifactId>
    <version>${version}</version>
</dependency>

Gradle

dependencies {
    compile 'com.hazelcast:spring-data-hazelcast:${version}'
}

Usage

Spring Configuration

@Configuration
@EnableHazelcastRepositories(basePackages={"example.springdata.keyvalue.chemistry"}) // <1>
public class ApplicationConfiguration {
    @Bean
    HazelcastInstance hazelcastInstance() {     // <2> 
        return Hazelcast.newHazelcastInstance();
        // return HazelcastClient.newHazelcastClient();
    }
}

Enables Spring Data magic for Hazelcast. You can specify basePackages for component scan.
Instantiates Hazelcast instance (a member or a client)

Repository Definition

public interface SpeakerRepository extends HazelcastRepository<Speaker, Long> {}

Test of Repository

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfiguration.class)
public class AppTest {
    @Autowired
    SpeakerRepository speakerRepository;

    @Test
    public void testStart(){
        speakerRepository.findAll();
    }
}
