查找配置文件路径
ApplicationHome home = new ApplicationHome(getClass());
File jarFile = home.getSource();
String ApplicationHomePath = jarFile.getParent();
System.out.println("ApplicationHomePath"+ApplicationHomePath);

String studentPathC1=Thread.currentThread().getContextClassLoader().getResource(fileName).getPath();
System.out.println("c1 path: "+studentPathC1);

File fileStudent = new File(studentPathC1);
if(!fileStudent.exists()){
    fileStudent = new File(ApplicationHomePath+"\classes\"+fileName);
}



//System.loadLibrary("libJavaForJniDemo");
// System.load("libJavaForJniDemo.dll");
