Springboot 2.x 版本 RedisCacheManager 类的配置，【与 1.x 略有不同】

1、1.x 配置方式

@Beanpublic CacheManager cacheManager(RedisTemplate redisTemplate) {    RedisCacheManager cacheManager= new RedisCacheManager(redisTemplate);    cacheManager.setDefaultExpiration(60);    Map
    
      expiresMap=new HashMap<>();    expiresMap.put("Product",5L);    cacheManager.setExpires(expiresMap);    return cacheManager;}
    

2、2.x 配置方式

@Bean    public CacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {        RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()                .entryTtl(Duration.ofHours(1)); // 设置缓存有效期一小时        return RedisCacheManager                .builder(RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory))                .cacheDefaults(redisCacheConfiguration).build();    }
