与文件路径相关的操作
（1）判断给定路径是否是绝对路径
例如d:\bin和E：是绝对路径，而..\temp 和 test\ccc 不是绝对路径
Java代码
- public static final String OSNAME = System.getProperty("os.name");
- public static boolean isWindows = false;
- public static boolean isHP_UX = false;
- public static boolean isSolaris = false;
- public static boolean isOS32bit = true;
- static {
- if (SystemHWUtil.OSNAME.toLowerCase().contains("window")) {
- isWindows = true;
- }
- if (SystemHWUtil.OSNAME.toLowerCase().contains("hp-ux")) {
- isHP_UX = true;
- }
- if (SystemHWUtil.OSNAME.toLowerCase().contains("Solaris")) {
- isSolaris = true;
- }
- if (SystemHWUtil.OSARCH.contains("64")) {
- isOS32bit = false;
- }
- }
- /***
- * Determine whether it is an absolute path.
- *
- * @param input
- * @return
- */
- public static boolean isAbsolutePath(String input) {
- if (ValueWidget.isNullOrEmpty(input)) {
- throw new RuntimeException("can not be null");
- }
- if (isWindows) {
- return input.matches("^[a-zA-Z]:\\\\?.*");//"^[a-zA-Z]:\\\\.*"
- } else {
- return input.matches("^/.*");
- }
- }
测试代码：
Java代码
- @Test
- public void test_isAbsolutePath(){
- String path="d:\\bin";
- System.out.println(SystemHWUtil.isAbsolutePath(path));
- }
执行结果：true
（2）打开指定路径
Java代码
- /***
- *
- * @param folder
- * : directory
- */
- public static void open_directory(Object folderObj) {
- if (ValueWidget.isNullOrEmpty(folderObj)) {
- return;
- }
- File file = null;
- if (folderObj instanceof JTextField) {
- JTextField tf = (JTextField) folderObj;
- file = new File(tf.getText());
- } else if (folderObj instanceof String) {
- file = new File((String) folderObj);
- } else {
- file = (File) folderObj;
- }
- if (!file.exists()) {
- return;
- }
- Runtime runtime = null;
- try {
- runtime = Runtime.getRuntime();
- if (!SystemHWUtil.isWindows) {
- // System.out.println("is linux");
- runtime.exec("nautilus " + file.getAbsolutePath());
- } else {
- runtime.exec("cmd /c start explorer " + file.getAbsolutePath());
- }
- } catch (IOException ex) {
- ex.printStackTrace();
- } finally {
- if (null != runtime) {
- runtime.runFinalization();
- }
- }
- }
- /***
- *
- * @param filePath
- * : only regular file
- */
- public static boolean open_file(Object folderObj) {
- if (ValueWidget.isNullOrEmpty(folderObj)) {
- return false;
- }
- File file = null;
- if (folderObj instanceof JTextField) {
- JTextField tf = (JTextField) folderObj;
- file = new File(tf.getText());
- } else if (folderObj instanceof String) {
- file = new File((String) folderObj);
- } else {
- file = (File) folderObj;
- }
- if (!file.exists()) {
- return false;
- }
- Runtime runtime = null;
- try {
- runtime = Runtime.getRuntime();
- if (!SystemHWUtil.isWindows) {
- // System.out.println("is linux");
- runtime.exec("nautilus " + file.getAbsolutePath());
- } else {
- runtime.exec("cmd /c start explorer /select,/e, "
- + file.getAbsolutePath());
- }
- } catch (IOException ex) {
- ex.printStackTrace();
- return false;
- } finally {
- if (null != runtime) {
- runtime.runFinalization();
- }
- }
- return true;
- }
