Question

我在课堂上有2个功能：

login()登录网站
Send_Sms()发送短信

这里我想为函数添加2个线程，以便可以在Send_Sms成功完成后开始发送短信的方式控制函数login()的优先级，否则程序无效。

这是我到目前为止所做的：

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.io.Writer;
import java.util.logging.Level;
import java.util.logging.Logger;


public class RunThreads extends Thread
{
    public void Login(String username,String password)
    {
        try
        {
            // creates the batch file for Logging into abc.com server
            Writer output = null;
            String UserAgent = "Mozilla/5.0 (Windows NT 5.1;KM:10.0.2)";
            String postdata = "\"" + "username="+username+ "&password=" + password + "&button=Login" + "\"";
            String MainStream = "c:\\wget.exe --output-document=login.html --user-agent=" + "\"" + UserAgent + "\"" + " --max-redirect=10 --cookies=on --keep-session-cookies --save-cookies=cookie.txt --post-data " + postdata + " http://www.abc.com/Login1.action;";
            File file = new File("login.bat");
            output = new BufferedWriter(new FileWriter(file));
            output.write(MainStream);
            output.close();
            Runtime.getRuntime().exec("cmd /c start login.bat");
        }
        catch (IOException ex)
        {
            Logger.getLogger(Save_Credentials.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
    public void SendSms(String mobno,String content) throws IOException
    {
                Writer output = null;
                String UserAgent = "Mozilla/5.0 (Windows NT 5.1;KM:10.0.2)";
                String MainStream = "c:\\wget.exe --output-document=quicksms.html --user-agent=" + "\"" + UserAgent + "\"" + " --referer=http://www.abc.com/jsp/SMS.jsp --cookies=on --keep-session-cookies --load-cookies=cookie.txt --save-cookies=cookie.txt --post-data "+"\""+"&HiddenAction=instantsms&catnamedis=Birthday&Action=gstahsbdf5346g&chkall=on&MobNo="+mobno+"&textArea="+content+"\""+" http://www.abc.com/quicksms.action;";
                File file = new File("SendSms.bat");
                output = new BufferedWriter(new FileWriter(file));
                output.write(MainStream);
                output.close();
                Runtime.getRuntime().exec("cmd /c start SendSms.bat");
    }
    public static void main(String[] args) 
    {


    }
}

Answer 1

由于登录失败时无法发送短信，正如您自己所说：

可以以某种方式控制Send_Sms功能的优化它在login（）完成后开始发送短信成功否则程序将无法正常工作。

然后这两个任务是顺序耦合的，这意味着在不同的线程上并行执行它们是没有意义的。只需在一个线程上按顺序执行它们。

使用Java Swing开发SMS发送应用程序
