Question

我正在尝试使用java调用powershell脚本..我的代码无效... 我创建了一个登录窗口。单击登录按钮时，需要调用powershell脚本...

        }
    }

};
//Container contentPane = Jframe.getContentPane();
//contentPane.setLayout(new FlowLayout());
setContentPane(panel);
setLayout(new FlowLayout());
placeComponents(panel);

    }
    private static void placeComponents(JPanel panel) {

        panel.setLayout(null);

        JLabel userLabel = new JLabel("User");

        JTextField userText = new JTextField(20);
        userText.setBounds(130,100, 160, 25);
        panel.add(userText);

        JLabel passwordLabel = new JLabel("Password");
        passwordLabel.setBounds(40, 140, 80, 25);
        panel.add(passwordLabel);

        JPasswordField passwordText = new JPasswordField(20);
        passwordText.setBounds(130, 140, 160, 25);
        panel.add(passwordText);

        JButton loginButton = new JButton("login");
        loginButton.setBounds(100, 180, 80, 25);
        runn();
        panel.add(loginButton);

        JButton cancelButton = new JButton("cancel");
        cancelButton.setBounds(220, 180, 80, 25);
         cancelButton.addActionListener(new ActionListener() 
            {
                public void actionPerformed(ActionEvent e)
                {
                  // statusLabel.setText("abcd");
                      System.exit(0);
                } });
        panel.add(cancelButton);
    }

public void runn() {
        Runtime runtime = Runtime.getRuntime();
        Process proc = runtime.exec("powershell C:\\testscript.ps1");
        InputStream is = proc.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader reader = new BufferedReader(isr);
        String line;
        try {
        while ((line = reader.readLine()) != null)
        {
            System.out.println(line);
        }
        reader.close();
        proc.getOutputStream().close();
        } catch (Exception e) {
            e.printStackTrace();
            }
}
public static void main(String[] args) 
{
    GraphicsEnvironment ge
            = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice gd = ge.getDefaultScreenDevice();
    boolean isPerPixelTranslucencySupported
            = gd.isWindowTranslucencySupported(PERPIXEL_TRANSLUCENT);
    if (!isPerPixelTranslucencySupported) 
    {
        System.out.println("Per-pixel translucency is not supported");
        System.exit(0);
    }
    SwingUtilities.invokeLater(new Runnable()
    {
    @Override
    public void run()
    {
         Credential gtw = new Credential();
         gtw.setVisible(true);
             }
    });
}

}

我还想知道是否可以使用jni使用java类调用powershell ..我收到的错误是：

Answer 1

你是什么意思

我的代码无效？

你收到任何错误吗？如果是这样，那是什么。你可以发布你的异常追踪。

从您的代码Process proc = runtime.exec("powershell D:\\exportasxml.ps1");

您是否将powershell路径设置为环境变量？您需要确保正在执行的命令位于正确的路径中。

使用java swing调用powershell脚本
