春季Redis的问题：从Redis的缓存GetAllCacheNames不与RedisCacheManager

Question

工作

你好下面是我的Redis的缓存配置，而我试图让所有的cachename使用Redis的存储服务器上：

redisCacheManager.getCacheNames（）

但它没有给我在我的redis服务器中存在的cacheName。

我使用cacheName可缓存标注前缀：@Cacheable（ “cacheName”）

我有2个问题吗？

1）为什么我无法获取我存储在redis服务器中的cacheNames。 2）我怎样才能动态创建前缀cacheName，因为我不想为它们编写单独的方法？

@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，尝试

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