Spring Redis 问题：Redis 缓存中的 GetAllCacheNames 不适用于 RedisCacheManager

Question

您好，下面是我的 redis 缓存配置，我正在尝试使用以下方式获取存储在 redis 服务器上的所有缓存名称：

redisCacheManager.getCacheNames()

但它没有给我 redis 服务器中存在的 cacheName。

我使用 Cachable 注解为 cacheName 添加前缀：@Cacheable("cacheName")

我这里有 2 个问题？

1) 为什么我无法获取我存储在 redis 服务器中的缓存名称。 2）我不想为所有这些都写单独的方法，如何动态创建前缀cacheName？

@Bean
JedisConnectionFactory jedisConnectionFactory() {
    JedisConnectionFactory factory = new JedisConnectionFactory();
    factory.setHostName(redisHost);
    factory.setPort(redisPort);
    factory.setUsePool(true);
    return factory;
}

@Bean
RedisTemplate<Object, Object> redisTemplate() {
    RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<Object, Object>();
    redisTemplate.setConnectionFactory(jedisConnectionFactory());
    redisTemplate.setDefaultSerializer(new StringRedisSerializer());
   // redisTemplate.setHashValueSerializer(new Jackson2JsonRedisSerializer<>(Object.class));
    return redisTemplate;
}

@Bean
CacheManager cacheManager() {
    // configuration to set the time to expire in seconds, messageCache is name of method
    Map<String,Long> cacheMap = new HashMap<String, Long>();
    //cacheMap is the name of the map where we put all the method names for which we want time to expire.
    RedisCacheManager redisCacheManager = new RedisCacheManager(redisTemplate());
    redisCacheManager.setUsePrefix(true);
    //redisCacheManager.setExpires(cacheMap);
    return redisCacheManager;
}

对于 CacheNames，请尝试

@Autowired CacheManager cacheManager     
cacheManager.getCacheNames().forEach(cacheM-> {System.out.println(cacheM);});
