执行tracert线程：

class MyThread implements Runnable {

    public static Logger logger = Logger.getLogger(MyThread.class);

    private String url;

    public String getUrl() {
	return url;
    }

    public void setUrl(String url) {
	this.url = url;
    }

    @Override
    public void run() {
	try {
	    logger.info("start tracert ...");
	    logger.info("cmd  tracert " + this.url + " see tracert.log");
	    BufferedWriter out = new BufferedWriter(new FileWriter(MyStringUtils.USER_DIR + "tracert.log"));
	    Process process = Runtime.getRuntime().exec("cmd /c tracert " + this.url);
	    BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream(), "GBK"));
	    String line;
	    out.write("== > Call tracert time : " + new Date() + "\n");
	    out.write("===============start=================\n");
	    while ((line = reader.readLine()) != null) {
		out.write(line);
		out.newLine();
	    }
	    out.write("================end==================\n");
	    out.flush();
	    out.close();
	} catch (Exception e) {
