Play Framework 中的咖啡因缓存不会 return 缓存响应
Caffeine cache in Play Framework doesn't return cached responses
我在我的 java Play Framework 作业中使用 Caffeine 缓存实现来缓存传出的 http 请求，我发现尽管缓存已启动并且 运行，我的服务仍然每次都访问外部服务器，而不是从缓存中返回值。
而且我看到日志中记录的密钥总是相同的。
所以我看到 freshnessLifetime 没有设置，所以这可能意味着缓存立即过期。但我仍然不知道如何在配置中设置它
我没有更改我的 java 代码，如果我需要这样做，我找不到任何示例，或者我应该只有一个缓存配置适用于所有传出请求。
如有任何帮助，我将不胜感激

我真的找到了它是如何工作的。缓存不应该像 Redis 或 Memcached 这样的单独服务那样管理生命周期，而是像浏览器一样运行，并由 HTTP 响应中的 headers 管理。

我真的找到了它是如何工作的。缓存不应该像 Redis 或 Memcached 这样的单独服务那样管理生命周期，而是像浏览器一样运行，并由 HTTP 响应中的 headers 管理。 这里：https://github.com/playframework/cachecontrol/blob/e4694aa0665e2ccc5030ae1cf1d0b15ad5b98471/src/main/scala/com/typesafe/play/cachecontrol/FreshnessCalculator.scala#L42
所以对我来说解决方案是更改服务器以使其正常服务header：Cache-Control "max-age=3600, public"
