spring cache 配置缓存存活时间

Spring Cache @Cacheable本身不支持key expiration的设置，以下代码可自定义实现Spring Cache的expiration，针对Redis、SpringBoot2.0。直接上代码：@Service@Configurationpublic class CustomCacheMng{ private Logger logger = LoggerFactory.getLogger(this.getClass()); // 指明自定义cacheManager的bean name @Cacheable(value = “test”,key = “‘obj1’",cacheManager = “customCacheManager”) public User cache1(){ User user = new User().setId(1); logger.info(“1”); return user; } @Cacheable(value = “test”,key = “‘obj2’”) public User cache2(){ User user = new User().setId(1); logger.info(“2”); return user; } // 自定义的cacheManager，实现存活2天 @Bean(name = “customCacheManager”) public CacheManager cacheManager( RedisTemplate<?, ?> redisTemplate) { RedisCacheWriter writer = RedisCacheWriter.lockingRedisCacheWriter(redisTemplate.getConnectionFactory()); RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig().entryTtl(Duration.ofDays(2)); return new RedisCacheManager(writer, config); } // 提供默认的cacheManager，应用于全局 @Bean @Primary public CacheManager defaultCacheManager( RedisTemplate<?, ?> redisTemplate) { RedisCacheWriter writer = RedisCacheWriter.lockingRedisCacheWriter(redisTemplate.getConnectionFactory()); RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig(); return new RedisCacheManager(writer, config); }}
