Prepare to load the docker container. After the project is packaged, it is a jar package, and then it is packaged into an image through dockerFile, but the file under resources cannot be found.

In order to solve this problem, I tried all the basic schemes and found that the file could not be found.

Local use

Resource [] resources = resource.getResources ("classpath:libs")

It's no problem to get it in a way.

After the study, it is found that when getting the path, it is actually obtained from the container, rather than looking for it in the jar package, so add the following code to dockerfile.

After adding this paragraph, the file will be placed in the container under the root directory / libs, and the things under this folder will also be copied.

You can write the root path of the project directly.
