Question

我是石英和javamail的新手，但我需要通过批处理作业发送电子邮件。我试过了 1.发送单个java类的电子邮件：success 2.用夸脱（只有println）运行工作：成功 3.用夸脱运行工作（发送电子邮件）：失败

这是我的工作班：

import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
import org.quartz.*;


public class EmailJob implements Job {

    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        try {
            EmailSender es = new EmailSender();
            es.sendBillingEmail();

            System.out.println("Job Email Runnning");
            final String username = "abcde@mydomain.com";
            final String password = "xxxxxxxxxx";

            Properties props = new Properties();
            props.put("mail.smtp.starttls.enable", "true");
            props.put("mail.smtp.auth", "true");
            props.put("mail.smtp.host", "smtp.mydomain.com");//smtp.gmail.com
            props.put("mail.smtp.port", "587");//587

            Session session = Session.getInstance(props,
                    new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(username, password);
                }
            });
            System.out.println("Job Email Running 2");
            // Sending email
            try {

                Message message = new MimeMessage(session);

                message.setFrom(new InternetAddress("abcde@mydomain.com"));
                message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("myemail@gmail.com"));
                message.setSubject("Test Email");
                String body = "Dear Bapak Recipients"
                        + "<br>Just test email";

                message.setContent(body, "text/html; charset=utf-8");
                Transport.send(message);

                System.out.println("Done");

            } catch (MessagingException e) {
                throw new RuntimeException(e);
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }


}

结果：

Job Email Running (i got this message in console)
Job Email Running 2 (i code this but didnt see in console, 
         my suspect theres an error when creating session)

quartz.properties

# Generic configuration - probably not needed, most of this is just the defaults
org.quartz.scheduler.instanceName = MyScheduler
org.quartz.scheduler.instanceId = 1
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 20
org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

# Configure it to look in the quartz.xml for the job schedules
org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
org.quartz.plugin.jobInitializer.fileNames = quartz.xml
org.quartz.plugin.jobInitializer.failOnFileNotFound = true
org.quartz.plugin.jobInitializer.scanInterval = 120

控制台中没有错误。我不知道哪里出错了。需要你们的帮助。

最后，它可以工作。我将库更新到Java Mail版本1.6.0 ..并使用相同的代码工作。希望这对我有同样问题的其他帮助。您可以通过以下链接下载：
