示例1: applyCacheSeconds
import org.springframework.http.CacheControl; //导入方法依赖的package包/类
/**
* Apply the given cache seconds and generate corresponding HTTP headers,
* i.e. allow caching for the given number of seconds in case of a positive
* value, prevent caching if given a 0 value, do nothing else.
* Does not tell the browser to revalidate the resource.
* @param response current HTTP response
* @param cacheSeconds positive number of seconds into the future that the
* response should be cacheable for, 0 to prevent caching
