Step 1: First get the classpath path

1
String classpath = this.getClass().getResource("/").getPath() .replaceFirst("/", "");
This way you can get the classpath path, similar to:

F:/projects/JavaStudyParent/study-springmvc-junit-test/target/springmvc-junit-test/WEB-INF/classes/

Then intercept WEB-INF/classes to get the WebAPP directory:
1
String webappRoot = classpath.replaceAll("WEB-INF/classes/", "");
The result is:

F:/projects/JavaStudyParent/study- springmvc-junit-test/target/springmvc-junit-test/

You can get all the files in this folder through this path
