Spring Boot @Cachable -如何在运行时找出过期日期时间？

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.Cache;
import org.springframework.cache.CacheManager;
import org.springframework.stereotype.Component;

@Component
public class CacheExpirationExample {

    @Autowired
    private CacheManager cacheManager;

    public void getCacheExpirationTime() {
        Cache cache = cacheManager.getCache("myCache"); // 替换为实际使用的缓存名称
        if (cache != null) {
            long expirationTime = cache.getNativeCache().getExpirationTime(); // 获取缓存的过期时间
            System.out.println("缓存过期时间：" + expirationTime);
        }
    }
}
