我正在嘗試通過 java 連接到 Redis，我有以下配置，@SpringBootApplication@Configuration@ComponentScan(basePackages = "com.infy.redisDemo")public class RedisDemoApplication {    @Bean    public LettuceConnectionFactory getConnectionFactory(){        LettuceConnectionFactory lettuceConnectionFactory = new LettuceConnectionFactory("localhost",6379);        return lettuceConnectionFactory;    }    @Bean    public RedisTemplate<String,Object> getRedisTemplate(){        RedisTemplate<String, Object> redisTemplate = new RedisTemplate();        redisTemplate.setConnectionFactory(getConnectionFactory());        return redisTemplate;    }    public static void main(String[] args) {        SpringApplication.run(RedisDemoApplication.class, args);    }}我的回購課程：@Repositorypublic class UserRepoImpl implements UserRepository {    private RedisTemplate<String, Object> redisTemplate;    private HashOperations hashOperations;    public final String key = "USER";    public UserRepoImpl(RedisTemplate redisTemplate,      HashOperations hashOperations) {        this.redisTemplate = redisTemplate;        this.hashOperations = redisTemplate.opsForHash();    }    @Override    public void save(User user) {        hashOperations.put(key,user.getId(),user);    }    @Override    public void update(User user) {        hashOperations.put(key,user.getId(),user);    }    @Override    public Map findAll() {        return hashOperations.entries(key);    }}public interface UserRepository {    void save(User user);    void update(User user);    Map findAll();}
