springboot之redis cache TTL选项的使用

@Service
public class xxx {
    @Autowired
    private CacheProperties cacheProperties;
    public void xxx() {
        Duration ttl = this.cacheProperties.getRedis().getTimeToLive();
        if (null == ttl) {
            // 未获取到ttl，按照默认值处理
        } else {
            // 获取到ttl
            // ttl.getSeconds()
        }
    }
}
