如何将两个Cassandra数据源与Spring Boot和Spring数据一起使用？

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

spring.data.cassandra.contact-points=127.0.0.1
spring.data.cassandra.port=9042
spring.data.cassandra.username=myusername
spring.data.cassandra.password=mypassword

@Table("users")
public class User {
    @PrimaryKey
    private UUID id;
    private String name;
    // 其他属性和方法
}

@Repository
public interface UserRepository extends CassandraRepository<User, UUID> {
    // 自定义查询方法
    List<User> findByName(String name);
}

@Service
public class UserService {
    @Autowired
    private UserRepository userRepository;
    
    public User getUserById(UUID id) {
        return userRepository.findById(id).orElse(null);
    }
    
    public List<User> getUsersByName(String name) {
        return userRepository.findByName(name);
    }
    
    // 其他业务逻辑方法
}
