本文提供了一个自动化脚本，用于通过进程ID获取进程映像名称，并进一步关闭该进程。脚本利用了命令行工具如cmd.exe和Runtime类来实现这一功能。

    // 得到进程ID
    public static String getPID(String port)
    {

        InputStream is = null;
        BufferedReader br = null;
        String pid = null;
        try
        {
            String[] args = new String[]
            { "cmd.exe", "/c", "netstat -aon|findstr", port };
            is = Runtime.getRuntime().exec(args).getInputStream();
            br = new BufferedReader(new InputStreamReader(is));
            String temp = "";
            while((temp = br.readLine()) != null)
            {
                if ((temp.indexOf(":80 ")>0)&& (temp.indexOf("LISTENING")>0))
                {

                    String[] strs = temp.split("//s");
                    pid = strs[strs.length - 1];
                    break;
                }
            }

        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
        finally
        {
            try
            {
                br.close();
            }
            catch (IOException e)
            {
                e.printStackTrace();
            }
        }
        return pid;
    }

    // 根据进程ID得到映像名称
    public static String getProgramName(String pid)
    {

        InputStream is = null;
        BufferedReader br = null;
        String programName = null;
        try
        {
            String[] args = new String[]
            { "cmd.exe", "/c", "tasklist|findstr", pid };
            is = Runtime.getRuntime().exec(args).getInputStream();
            br = new BufferedReader(new InputStreamReader(is));
            String temp = br.readLine();
            if (temp != null)
            {
                String[] strs = temp.split("//s");
                programName = strs[0];
            }
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
        finally
        {
            try
            {
                br.close();
            }
            catch (IOException e)
            {
                e.printStackTrace();
            }
        }
        return programName;
    }

    // 根据映像名称关闭进程
    public static void killTask(String programName)
    {

        String[] args = new String[]
        { "Taskkill", "/f", "/IM", programName };
        try
        {
            Runtime.getRuntime().exec(args);
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
    }
