SpringBoot external jar not load

Question

i have a java project with spring boot and I need to load application.properties and dependency jar from external folder.

I tested by using the application.properties in the classpath, and the loader.path property work correctly.

When I use external properties file (I'm sure they're used) the loader.path not work correctly and the result is ClassNotFound because the jars are not loaded.

Also when i launch the application with **-Dloader.path=**xxx it's work correctly.

How can I solve the problem using external properties and jar?

Here is the document

1. You need to make sure the load order of different property files.
2. You need to make sure the loader.path points to the right path. I mean, relative path or absolute path? You'd better print it out.
