我正在从我的挥杆计划中间隔发送邮件。我想在点击发送电子邮件按钮时显示进度条。发送所有电子邮件后，进度条将达到100％完成。但是当邮件发送时，progrssbar并没有显示任何内容。
private void btnSendEmailsNowActionPerformed(java.awt.event.ActionEvent evt) {
btnSendEmailsNow.setEnabled(false);
Task task = new Task();
task.start();
//Load property files
loadProps();
//Read config file.
readConfig();
//Take filename "FromEmail_list" after reading config file.
BufferedReader br1=null;
BufferedReader br2=null;
String line1="",line2="";
String csvSplitBy=",";
String strMailFrom="",strPassword="";
String strSendTo="";
int countCSVFrom=0,countCSVSendTo;
System.out.println("strCSVFrom=" + strCSVFrom + ", strcsvSendTo=" + strCSVSendTo);
try{
br1=new BufferedReader(new FileReader(strCSVFrom));
br2=new BufferedReader(new FileReader(strCSVSendTo));
while((line1=br1.readLine())!=null){
countCSVFrom+=1;
String[] strarrFromEmail = line1.split(csvSplitBy);
strMailFrom=strarrFromEmail[0];
strPassword=strarrFromEmail[1];
System.out.println("strFrom="+strMailFrom + ", strPassword="+strPassword);
countCSVSendTo=0;
while((line2=br2.readLine())!=null){
System.out.println("line2="+line2.toString());
countCSVSendTo+=1;
String[] strMailTo=line2.split("\n");
strSendTo=strMailTo[0];
String subject = "Test mail";
String message="";
//inline image
Map<String,String> inlineImage=new HashMap<String,String>();
inlineImage.put("image1", "Logo.jpg");
frmEmailer mailer = new frmEmailer();
String filename=txtHTMLFile.getText();
System.out.println("filename=" + filename);
try{
message=mailer.readHTML(filename,message);
mailer.sendHtmlEmail(strhost, strport, strMailFrom, strPassword, strSendTo,
subject, message,inlineImage);
System.out.println("Email sent successfully.");
Random rand = new Random();
int randomNum = rand.nextInt((8 - 3) + 1) + 3;
System.out.println(randomNum);
Thread.sleep(randomNum*1000); //1000 microseconds = 1 seconds.
if(countCSVSendTo==2){
break;
}

答案 0 :(得分：0)
试试这段代码：
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt)
{
new Thread(){
public void run(){
btnSendEmailsNow.setEnabled(false);
//Load property files
loadProps();
//Read config file.
readConfig();
//Take filename "FromEmail_list" after reading config file.

BufferedReader br2=null;
String line1="",line2="";

String strSendTo="";
int countCSVFrom=0,countCSVSendTo;
int EmailCount = 0;
ProgressMonitor pm = new ProgressMonitor(null, "Loading Progress", "Getting Started...", 0, /*number of emails to be sent*/);
System.out.println("strCSVFrom=" + strCSVFrom + ", strcsvSendTo=" + strCSVSendTo);
try{
br1=new BufferedReader(new FileReader(strCSVFrom));
br2=new BufferedReader(new FileReader(strCSVSendTo));
while((line1=br1.readLine())!=null){
countCSVFrom+=1;
String[] strarrFromEmail = line1.split(csvSplitBy);
strMailFrom=strarrFromEmail[0];
strPassword=strarrFromEmail[1];
System.out.println("strFrom="+strMailFrom + ", strPassword="+strPassword);
countCSVSendTo=0;
while((line2=br2.readLine())!=null){
System.out.println("line2="+line2.toString());
countCSVSendTo+=1;
String[] strMailTo=line2.split("\n");
strSendTo=strMailTo[0];
String subject = "Test mail";
String message="";
//inline image
Map<String,String> inlineImage=new HashMap<String,String>();

mailer.sendHtmlEmail(strhost, strport, strMailFrom, strPassword, strSendTo,
subject, message,inlineImage);
System.out.println("Email sent successfully.");
EmailCount++;
pm.setProgress(EmailCount);
pm.setNote("Sent " + EmailCount + " Mails.");
Random rand = new Random();
int randomNum = rand.nextInt((8 - 3) + 1) + 3;
System.out.println(randomNum);
Thread.sleep(randomNum*1000); //1000 microseconds = 1 seconds.
if(countCSVSendTo==2){
break;
}
}catch (Exception ex) {

}
//System.out.println("countcsvfrom="+countCSVFrom + ", line1=" + line1.toString());
System.out.println("countcsvsendto="+countCSVSendTo);
}
JOptionPane.showMessageDialog(null, "Emails sent successfully!");
btnSendEmailsNow.setEnabled(true);
}catch(FileNotFoundException fnfe){
fnfe.printStackTrace();
JOptionPane.showMessageDialog(null, "Failed to send Email!");
}catch(IOException ioe ){
JOptionPane.showMessageDialog(null, "Failed to send Email!");

}
}
}.start();
}
您可以使用ProgressMonitor轻松完成该任务
