java 遍历某一目录下的所有class文件

public static void main(String[] args) throws IOException {String rootPath = ClassLoader.getSystemResource(".").getPath();File rootFile = new File(rootPath.replace("%20", " "));for(String file : listFiles(rootFile, new ArrayList<String>())){System.out.println(file);}}/** * 获取所有文件列表 * @param rootFile * @param fileList * @throws IOException */public static List<String> listFiles(File rootFile,List<String> fileList) throws IOException{File[] allFiles = rootFile.listFiles();for(File file : allFiles){if(file.isDirectory()){listFiles(file, fileList);}else{String path = file.getCanonicalPath();String clazz = path.substring(path.indexOf("classes")+8);fileList.add(clazz.replace("//", ".").substring(0,clazz.lastIndexOf(".")));}}return fileList;}
