刷新SparkJava提供的静态文件

Question

I'm doing a project using Spark Java. On the server side, some images are created and I want them to be available in the client. Since I have a static content directory, after creating the image on the server side, I place it in that directory. However, this file is not available unless I reboot the server. I guess there must be a way to refresh the static directory file for Spark Java on runtime so that requests of on-runtime created images can be fulfilled. Right?

Thanks!

Answer 1

The documentation says:

If you use staticFiles.location(...) , meaning you keep your static files in the classpath, static resources are copied to a target folder when you build your application. This means you have to make/build your project in order to refresh static files. A workaround for this is to tell Spark to read static files from the absolute path to the src-directory.

So use staticFiles.externalLocation() instead.

我已经通过将png编码为Base 64并将其作为响应发送给客户端来解决它。
