递归获取包下的class文件

    public class TestUrl {

    public static void main(String[] args) {
        String pageName = "ogr.test";//包路径
        fileRecursive(pageName);
    }

    public static  void fileRecursive(String pageName) {
        URL url = Thread.currentThread().getClass().getResource("/" + pageName.replaceAll("\\.", "/"));//把/代替成.
        File file = new File(url.getFile());
        for(File tempFile: file.listFiles()){
            if(tempFile.isDirectory()){
                fileRecursive(pageName+"."+tempFile.getName());
            }else{
                System.out.println(pageName+"."+tempFile.getName());
            }
        }
