批量修改文件名

每次写博客时需要导入一些图片时都会遇到一个困惑，就是截图的名称太长不规范，不知道哪一张是指定的图片，还有就是手机拍的照片看那个名字就是不舒服。于是写了这一个小工具用于重命名文件名。文件批量重命名工具不局限于对图片的重命名对任意文件都适用。下面是相关源代码与解析：

由于代码比较小，就没有对其作分层处理。源代码包括界面设计、文件名识别、文件重命名处理等三部分。

代码编译环境：Jdk1.6和windows xp

1．  界面设计

先来看一下界面效果：

                   setResizable(false);

                   table.setModel(newDefaultTableModel(new Object[][] {}, new String[] { "旧文件名","新文件名" }));

                   scrollPane.setViewportView(table);

         }

如下为工具界面，质朴了一点，呵呵。

2．  文件识别

当浏览按钮被触发后，即启动文件读取功能；并且自动识别一个文件的后缀名。

         //文件读取路径

         protectedvoid do_button_actionPerformed(ActionEvent e) {

                   JFileChooserchooser = new JFileChooser();// 创建文件选择器

                   //设置只选择文件夹

                   /**Instruction to display only directories. DIRECTORIES_ONLY=1 */

                   chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);

                   intoption = chooser.showOpenDialog(this);// 显示打开对话框

                   if(option == JFileChooser.APPROVE_OPTION) {

                            dir= chooser.getSelectedFile();// 获取选择的文件夹

                   }else {

                            return;

                   }

                   forderField.setText(dir+ "");// 显示文件夹信息

                   File[]files = dir.listFiles();

                   intexIndex = files[0].toString().lastIndexOf(".");

                   StringexName = files[0].toString().substring(exIndex + 1);

                   extNameField.setText(exName);

                   DefaultTableModelmodel = (DefaultTableModel) table.getModel();

                   model.setRowCount(0);

                   for(File file : files) {

                            //System.out.println(file.getName());

                            model.addRow(newString[] { file.getName(), null });

                   }

         }

3．  文件重命名

触发开始按钮后处理重命名过程，对第二步中不正确的扩展名不予处理，所以不用担心文件会被处理出错。

/**

          * 开始按钮的事件处理方法

          *

          * @param e

          */

         protectedvoid do_startButton_actionPerformed(ActionEvent e) {

                   if(dir == null) {

                            JOptionPane.showMessageDialog(this,"请指定重命名路径（点击浏览）", "信息对话框", JOptionPane.WARNING_MESSAGE);

                            return;

                   }

 

                   Stringtemplet = templetField.getText();// 获取模板字符串

                   if(templet.isEmpty()) {

                            JOptionPane.showMessageDialog(this,"请确定重命名模板", "信息对话框", JOptionPane.WARNING_MESSAGE);

                            return;

                   }

                   //获取表格数据模型

                   DefaultTableModelmodel = (DefaultTableModel) table.getModel();

                   model.setRowCount(0);//清除表格数据

                   intbi = (Integer) startSpinner.getValue();// 获取起始编号

                   intindex = templet.indexOf("#");// 获取第一个“#”的索引

                   Stringcode = templet.substring(index);// 获取模板中数字占位字符串

                   //把模板中数字占位字符串替换为指定格式

                   templet= templet.replace(code, "%0" + code.length() + "d");

                   StringextName = extNameField.getText().toLowerCase();

                   //System.out.println(extName);

                   //if (extName.indexOf(".") == -1)

                   extName= "." + extName;

                   //获取文件中文件列表数组

                   File[]files = dir.listFiles(new ExtNameFileFilter(extName));

                   //File[] files = dir.listFiles();

                   //String parentFile =forderField2.getText();

                   //File SaveFile=new File(parentFile);

 

                   //System.out.println("aaaaaa="+SaveFile);

                   for(File file : files) {// 变量文件数组

                            //System.out.println(file.getName());

                            //格式化每个文件名称

                            Stringname = String.format(templet, bi++) + extName;

                            //把文件的旧名称与新名称添加到表格的数据模型

                            model.addRow(newString[] { file.getName(), name });

                            System.out.println("file="+ file);

                            System.out.println("filepare="+ file.getParent());

                            FileparentFile = file.getParentFile();// 获取文件所在文件夹对象

                            System.out.println("bbbbb="+ parentFile);

                            FilenewFile = new File(parentFile, name);

                            file.renameTo(newFile);//文件重命名

                   }

         }
