Question

I developped an application using spring-boot, I need to read a csv file that contain emails.

this is a snippet how I do:

public Set readFile         


        

Answer 1

I do not work with Spring, but I found the Javadoc of ClassPathResource that states:

Supports resolution as java.io.File if the class path resource resides in the file system, but not for resources in a JAR. Always supports resolution as URL.

try with getURL() instead of getFile().
