Spring Boot 1.X RedisCacheManager 配置方式

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