javaswing界面实现文件脱敏和还原,实现上传也可以拖拽上传包含文字字母数字字符的任意类型文件,获取文件内容,存放到String类型的数组, 界面中可以选择脱敏规则,规则1,对汉字进行脱敏,规则2,对字母进行脱敏,规则3,对数字进行脱敏,可以一次选择多个规则,点击加敏按钮后,将结果返还到界面中,可以对结果进行下载。上传文件点击还原按钮,可以对加敏的文件进行还原。请把界面也进行美化和良好布局,类似于应用程序的感觉。

好的,这是一个比较复杂的项目,需要实现以下几个功能:
1. 实现文件上传和拖拽上传。
2. 读取文件内容并存储到 String 数组中。
3. 实现脱敏规则,支持多种规则同时使用。
4. 点击加敏按钮后,将结果返还到界面中。
5. 可以对结果进行下载。
6. 点击还原按钮,可以对加敏的文件进行还原。
7. 界面美化和良好布局。
下面是一个简单的实现:

这个程序使用了 Java Swing 框架来实现界面。在界面上有三个按钮,分别是打开文件、加敏、还原。还有三个复选框,用于选择加敏规则。文件内容使用 JTextArea 来显示,可以拖拽滚动条来滚动文本。当用户选择打开文件时,程序会调用 JFileChooser 来打开一个文件选择对话框,让用户选择要打开的文件。当用户选择加敏时,程序会读取文件内容,并根据用户选择的加敏规则来加敏文件内容。加敏后的结果会显示在 JTextArea 中。当用户选择还原时,程序会根据用户选择的加敏规则来还原文件内容。还原后的结果会显示在 JTextArea 中。用户可以在 JTextArea 中选择并复制加敏或还原后的内容,并可以通过点击“下载”按钮将结果保存为文件。
注意:这个程序只是一个示例,实际应用中可能需要更多的功能和更严格的安全措施来确保文件内容不被泄露和篡改。
