基于redis的分布式缓存实现

Cache<String, String> cache = CacheBuilder
                .newBuilder("redisCacheKeyPrefix") //redis中缓存值的key前缀
                .expireTime(100) //过期时间 单位(秒) 默认过期时间为一年 
               .build(new CacheLoader<String, String>() {
                                   @Override
                                   public String load(String s) {
                                       //do something to get data
                                       String result = "to to cache data";
                                       return result;
                                   }
                               });

String cacheData = cache.get("cacheKey"); //get cache data

cache.refresh("cacheKey");// refresh cache
