我有问题，我认为这是合乎逻辑的问题。因为我不完全理解Quartz的概念。
我有以下类：a- BirthdayServlet.java，b- QuartzJob.java，c- MailSenderBean.java
目标是在我的Servlet中使用Quartz Scheduler发送电子邮件。这是类代码。
a-BirtdayServlet类
@WebServlet("/BirthdayServlet")
public class BirthdayServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public BirthdayServlet() {
super();
// TODO Auto-generated constructor stub
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse
* response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
// TODO Auto-generated method stub
response.getWriter().append("Served at:
").append(request.getContextPath());
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse
* response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.getWriter().println("I am Entering");
JobDetail job = JobBuilder.newJob(QuartzJob.class).build();
Trigger t1 = TriggerBuilder.newTrigger().withIdentity("SimpleTrigger").startNow().build();
Scheduler sc = StdSchedulerFactory.getDefaultScheduler();
sc.start();
sc.scheduleJob(job, t1);
response.getWriter().println("I am Leaving");
}
}
b- QuartzJob.java类
public class QuartzJob implements Job {
@Override
public void execute(JobExecutionContext arg0) throws JobExecutionException {
String body = ("TryingMyQuartz");
String subject = ("Recieved?");
String EmpEmail = ("amrr@gmail.com");
String sender = ("moha123@gmail.com");
String password = ("012344");
String senderDomain = ("@gmail.com");
String senderUsername = ("moha123");
MailSenderBean mailsender = new MailSenderBean();
mailsender.sendEmail(sender, senderUsername, password, EmpEmail, subject, body, senderDomain);
}
}
c- MailSenderBean.java
public class MailSenderBean {
public void sendEmail(String sender, String senderUsername, String password, String EmpEmail, String subject,
String body, String senderDomain) {
Properties props = System.getProperties();
if (senderDomain.equals("@gmail.com")) {
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.fallback", "false");
Session mailSession = Session.getDefaultInstance(props, null);
mailSession.setDebug(true);
Message mailMessage = new MimeMessage(mailSession);
try {
mailMessage.setFrom(new InternetAddress(sender));
} catch (MessagingException e) {
// Sender mail not found
}
try {
mailMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(EmpEmail));
} catch (MessagingException e) {
// Recipent mail not found
}
try {
mailMessage.setContent(body, "text/html");
mailMessage.setSubject(subject);
Transport transport = mailSession.getTransport("smtps");
transport.connect("smtp.gmail.com", senderUsername, password);
transport.sendMessage(mailMessage, mailMessage.getAllRecipients());
} catch (MessagingException e) {
// Cannot transport that message Sorry!
}
}
}
}
我确信MailSenderBean工作正常。所以问题在于Servlet或QuartzJob类。我不知道我的代码到底有什么问题。但它没有用。并且不显示response.getwirter（“我正在离开”）。因此程序在制定Job或Quartz时会终止。
