如何使用springboot- data -couchbase配置多个couchbase数据源？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-couchbase</artifactId>
</dependency>

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

@Configuration
public class CouchbaseConfig1 extends AbstractCouchbaseConfiguration {

    @Override
    public String getConnectionString() {
        return "couchbase://host1";
    }

    @Override
    public String getUserName() {
        return "username1";
    }

    @Override
    public String getPassword() {
        return "password1";
    }

    @Override
    protected String getBucketName() {
        return "bucket1";
    }

    @Override
    protected String getBucketPassword() {
        return "bucketPassword1";
    }
}

@Configuration
public class CouchbaseConfig2 extends AbstractCouchbaseConfiguration {

    @Override
    public String getConnectionString() {
        return "couchbase://host2";
    }

    @Override
    public String getUserName() {
        return "username2";
    }

    @Override
    public String getPassword() {
        return "password2";
    }

    @Override
    protected String getBucketName() {
        return "bucket2";
    }

    @Override
    protected String getBucketPassword() {
        return "bucketPassword2";
    }
}

@Autowired
@Qualifier("couchbaseTemplate1")
private CouchbaseTemplate couchbaseTemplate1;

@Autowired
@Qualifier("couchbaseTemplate2")
private CouchbaseTemplate couchbaseTemplate2;
