如何重新加载谷歌番石榴缓存

Question

我正在研究dropwizard-java项目，直到谷歌番石榴缓存功能我都有代码。一旦将值写入文件，我需要更新缓存。当我打开某个路径时，它应该更新服务器中的缓存而无需重新启动。如果有人知道，请帮助我编写用于重新加载缓存的代码。

There are various ways to do this but if you are synchronously writing a file and then want to update your Guava Cache to load that file then you can use direct insertion .
