递归遍历文件夹&读取ini文件&获取ini的全部key

遍历文件夹

public class Test{public static void showAllFiles(File dir) throws Exception {File[] fs = dir.listFiles();for (int i = 0; i < fs.length; i++) {System.out.println(fs[i].getAbsolutePath());if (fs[i].isDirectory()) {try {showAllFiles(fs[i]);} catch (Exception e) {}}}}public static void main(String[] args) {// TODO Auto-generated method stubFile root = new File("c:");try {showAllFiles(root);} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

 读取ini文件获取相关key的value值

public static String ReadINI(String FilePath, String Key) {String Value = "";File file = new File(FilePath);try {FileReader filereader = new FileReader(file);Properties p = new Properties();try {p.load(filereader);Value = p.getProperty(Key);} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}} catch (FileNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();}return Value;} 

获取ini文件的所有key

public static Set<String> ReadINIforKeysSet(String FilePath) {Set<String> set = null;File file = new File(FilePath);try {FileReader filereader = new FileReader(file);Properties p = new Properties();try {p.load(filereader);set = (Set<String>) p.stringPropertyNames();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}} catch (FileNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();}return set;}
