BasicTextEncryptor textEncryptor = new BasicTextEncryptor();
//加密所需的salt(鹽)
textEncryptor.setPassword("uoj20@d03jd");
//要加密的數據（數據庫的用戶名或密碼）
String username = textEncryptor.encrypt("root");
String password = textEncryptor.encrypt("myadmin);
System.out.println("username:"+username);
System.out.println("password:"+password);
```
3. 配置文件解密
