Question

我创建了一个java项目，通过使用netbeans单击问题和答案按钮来显示问题和答案。我将这些图像放在“src”文件夹中。也就是那些加密后放置的图像。完成我的项目后，我制作.jar文件。当我运行.jar文件时，它说 “java.io.filenotfoundexception：”file_path“（系统找不到指定的路径）”。我怎样才能解决这个问题。提前谢谢。

  public static void main(String[]args){

      String imageName[] ={"A01","A02","A03","B01","B02","B03"};

      String imageNameEncrypy[] ={"A001","A002","A003","B001","B002","B003"};

      for(int i=0;i<imageName.length;i++){ 

      try{

        //FileInputStream file;

        FileInputStream  file = new FileInputStream("src/image2/"+imageName[i]+".jpg");

        FileOutputStream output = new FileOutputStream("src/image2/"+imageNameEncrypy[i]+".jpg");

        byte j[]="NiTh5252".getBytes();

        SecretKeySpec kye = new SecretKeySpec(j,"DES");

        System.out.println(kye);

        Cipher enc = Cipher.getInstance("DES");

        enc.init(Cipher.ENCRYPT_MODE,kye);

        CipherOutputStream cos = new CipherOutputStream(output, enc);

        byte[] buf = new byte[1024];

        int read;

        while((read=file.read(buf))!=-1){

            cos.write(buf,0,read);

        }

        file.close();

        output.flush();

        cos.close();

         JOptionPane.showMessageDialog(null,"Suscess");

    }catch(Exception e){

         JOptionPane.showMessageDialog(null,e);

    }

      }

     }

解密代码

    int k=i;

    String questionImage[]={"","B001","B002","B003"};

    String questionDecryptImageName=questionImage[k];

    String afterDrcryptName[]={"A.jpg","B.jpg","C.jpg","D.jpg"};

    try{

        FileInputStream file = new FileInputStream("src/learning/dvd/Temp2/"+questionDecryptImageName+".jpg");

    FileOutputStream output = new FileOutputStream("src/learning/dvd/Temp2/"+afterDrcryptName[k]);

        byte j[]="NiTh5252".getBytes();

        SecretKeySpec kye = new SecretKeySpec(j,"DES");

        System.out.println(kye);

        Cipher enc = Cipher.getInstance("DES");

        enc.init(Cipher.DECRYPT_MODE,kye);

        CipherOutputStream cos = new CipherOutputStream(output, enc);

        byte[] buf = new byte[1024];

        int read;

        while((read=file.read(buf))!=-1){

            cos.write(buf,0,read);

        }

        file.close();

        cos.close();

        output.flush();  

    }catch(Exception e){

        JOptionPane.showMessageDialog(null, e);

    }

}

}

Answer 1

您无法访问“src / image2”中的文件，因为jar中没有文件夹。

在其他问题Add image to JAR Java

中使用getClass().getResource()

我将我的图像文件保存在java项目中以制作.jar
