我使用Java swing做了一个zip解压缩助手,界面如下:
使用的依赖包:
为什么不用java 自带的ZipUtil呢?因为 没有乱码问题.
技术问题
一,如何使窗口居中?
Java代码
- Dimension screensize = Toolkit.getDefaultToolkit().getScreenSize();
- setSize(600, 280);
- Dimension framesize = getSize();
- int x = (int)screensize.getWidth()/2 - (int)framesize.getWidth()/2;
- int y = (int)screensize.getHeight()/2 - (int)framesize.getHeight()/2;
- setLocation(x,y);
二,增加助记键
效果:按Alt+C 时触发压缩按钮的点击事件,按Alt+D 触发解压按钮的单击事件
三,全局快捷键
Java代码
- /***
- * 设置全局快捷键,按Alt+r ,则命令输入框自动聚焦
- */
- private void globalShortcutKeys(){
- //Add global shortcuts
- Toolkit toolkit = Toolkit.getDefaultToolkit();
- // 注册应用程序全局键盘事件, 所有的键盘事件都会被此事件监听器处理.
- toolkit.addAWTEventListener(
- new java.awt.event.AWTEventListener() {
- @Override
- public void eventDispatched(AWTEvent event) {
- if (event.getClass() == KeyEvent.class) {
- KeyEvent kE = ((KeyEvent) event);
- // 处理按键事件 Ctrl+Enter
- if ((kE.getKeyCode() == KeyEvent.VK_R)
- && (((InputEvent) event)
- .isAltDown())&& kE.getID() == KeyEvent.KEY_PRESSED) {
- System.out.println("Alt+r");
- shScriptTF.requestFocus();
- } }
- }
- }, java.awt.AWTEvent.KEY_EVENT_MASK);
- }
四,解压核心代码
Java代码
- /***
- * 解压zip
- *
- * @param zipFile
- * @param decompressLoc
- * :解压之后的文件所在目录
- * @throws ArchiveException
- * @throws IOException
- */
- public static boolean deCompressRecursion(String zipFile,
- File decompressLoc, String charSet) throws ArchiveException,
- IOException {
- FileInputStream fin = new FileInputStream(zipFile);
- ArchiveInputStream archIns = new ArchiveStreamFactory()
- .createArchiveInputStream(ArchiveStreamFactory.ZIP, fin);
- ZipArchiveInputStream zipIn = (ZipArchiveInputStream) archIns;
- boolean isSuccess = deCompressRecursion(zipIn, decompressLoc, charSet);
- zipIn.close();
- return isSuccess;
- }
- /***
- * 递归解压缩.
- *
- * @param zipIn
- * @param decompressLoc
- * @return
- * @throws IOException
- */
- private static boolean deCompressRecursion(ZipArchiveInputStream zipIn,
- File decompressLoc, String charset) throws IOException {
- ZipArchiveEntry zipEntry;
- if (ValueWidget.isNullOrEmpty(charset)) {
- charset = SystemHWUtil.CHARSET_UTF;
- }
- while (!ValueWidget.isNullOrEmpty(zipEntry = zipIn.getNextZipEntry())) {
- byte[] rawName = zipEntry.getRawName();
- String fileName = new String(rawName, charset);
- // System.out.println(fileName);
- if (zipEntry.isDirectory()) {// 是目录
- File newFolder = new File(decompressLoc, fileName);// 若子目录不存在，则创建之
- if(isPrint)
- System.out.println(newFolder.getAbsolutePath());
- if (!newFolder.exists()) {
- newFolder.mkdir();
- }
- // deCompressRecursion(zipIn, decompressLoc,charset);
- } else {// 是普通文件
- File singFile = new File(decompressLoc, fileName);
- if(isPrint)
- System.out.println(singFile.getAbsolutePath());
- if (singFile.exists()) {// 若解压后的文件已经存在，则直接退出
- GUIUtil23.warningDialog("File \""
- + singFile.getAbsolutePath() + "\" does exist.");
- return false;
- }
- /**
- * 以下四行代码是后来添加的，为了解决父目录不存在的问题
- */
- File fatherFolder = singFile.getParentFile();
- if (!fatherFolder.exists()) {
- fatherFolder.mkdirs();
- }
- FileUtils.writeIn2Output(zipIn, new FileOutputStream(singFile),
- true, false);
- }
- }
- return true;
- }
五,压缩核心代码
Java代码
- /***
- * 压缩文件.
- *
- * @param zipFile
- * @param folderPaths
- * @return
- * @throws ArchiveException
- * @throws IOException
- */
- public static boolean compressZipRecursion(String zipFile,
- String folderPaths) throws ArchiveException, IOException {
- FileOutputStream fou = new FileOutputStream(zipFile);
- ArchiveOutputStream archOuts = new ArchiveStreamFactory()
- .createArchiveOutputStream(ArchiveStreamFactory.ZIP, fou);
- if (archOuts instanceof ZipArchiveOutputStream) {
- ZipArchiveOutputStream zipOut = (ZipArchiveOutputStream) archOuts;
- List<ZipArchiveEntry> zipEntrys = getZipFileListRecursion(new File(
- folderPaths), null);
- for (int i = 0; i < zipEntrys.size(); i++) {
- ZipArchiveEntry zipEntry2 = zipEntrys.get(i);
- zipOut.putArchiveEntry(zipEntry2);
- File file = new File(folderPaths, zipEntry2.getName());
- if (!file.exists()) {
- return false;
- }
- if (!file.isDirectory()) {
- FileInputStream fin = new FileInputStream(file);
- // 不要关闭zipOut，关闭之前要执行closeArchiveEntry()
- FileUtils.writeIn2Output(fin, zipOut, false, true);
- }
- }
- closeZip(zipOut, true);
- }
- return true;
- }
