如何从spring应用程序连接到多个couchbase集群

spring.couchbase.bootstrap-hosts=host1,host2,host3
spring.couchbase.bucket.name=myBucket
spring.couchbase.bucket.password=myPassword

@Configuration
@EnableCouchbaseRepositories

    @Value("${spring.couchbase.bootstrap-hosts}")
    private String bootstrapHosts;

    @Override

    }

    @Override

        return bucketName;
    }

    @Override

    }

    @Override

        return CouchbaseCluster.create(environment, getBootstrapHosts());
    }
}

@Service
public class MyService {

    private final CouchbaseTemplate couchbaseTemplate;

    @Autowired
    public MyService(CouchbaseTemplate couchbaseTemplate) {
        this.couchbaseTemplate = couchbaseTemplate;
    }

    public void saveDocument(Document document) {
        couchbaseTemplate.save(document);
    }

    public Document getDocument(String id) {
        return couchbaseTemplate.findById(id, Document.class);
    }

    // 其他操作...
