发送附加邮件 Java Selenium 时获取 javax.mail.SendFailedException

Question

我编写了一个代码，用于发送具有附件文件但收到 javax.mail.SendFailedException 异常的邮件。下面是我写的代码。谁能纠正我为什么我得到异常 以下是异常

java.lang.RuntimeException: javax.mail.SendFailedException: Sending failed;
  nested exception is:
    class javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465;
  nested exception is:
    java.net.ConnectException: Connection timed out: connect
    at sendMail.sendMail2.execute(sendMail2.java:102)
    at sendMail.sel.main(sel.java:17)

下面是邮件类

package sendMail;


import java.util.Properties;

import javax.activation.DataHandler;
import javax.activation.DataSource;
import javax.activation.FileDataSource;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;


public class sendMail2 {
    public static void execute() throws Exception {

        final String username = "sender@gmail.com";
        final String password = "*********";

        Properties props = new Properties();
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.port", "465");

        Session session = Session.getInstance(props,
            new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username, password);
            }
        });

        try {

            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("sender@gmail.com"));
            message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("recepient@gmail.com"));
            message.setSubject("Testing Subject");
            message.setText("Dear Mail Crawler,"
                + "\n\n No spam to my email, please!");

            BodyPart messageBodyPart1 = new MimeBodyPart();  
            messageBodyPart1.setText("This is message body");  

            //4) create new MimeBodyPart object and set DataHandler object to this object      
            MimeBodyPart messageBodyPart2 = new MimeBodyPart();  

            String filename = "C:/Selenium Workspace/FMC360Automation/test-output/emailable-report.html";//change accordingly  
            DataSource source = new FileDataSource(filename);  
            messageBodyPart2.setDataHandler(new DataHandler(source));  
            messageBodyPart2.setFileName(filename);  

            //5) create Multipart object and add MimeBodyPart objects to this object      
            Multipart multipart = new MimeMultipart();  
            multipart.addBodyPart(messageBodyPart1);  
            multipart.addBodyPart(messageBodyPart2);  

            //6) set the multiplart object to the message object  
            message.setContent(multipart); 

            Transport.send(message);
            System.out.println("Done");
        } catch (MessagingException e) {
            throw new RuntimeException(e);
        }
    }
}

下面是基本的 Java Selenium 程序

package sendMail;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class sel {
    public static void main(String[] args) {
        WebDriver driver = new FirefoxDriver();
        driver.get("https://www.google.co.in/?gws_rd=cr,ssl&ei=sjPLVue4OI2IuATgkaWwCw");
        try {
            //Sendmail.execute("C:/Selenium Workspace/FMC360Automation/test-output/emailable-report.html");
                sendMail2.execute();
            driver.close();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }               
    }
}

使用您用于从 selenium 脚本发送邮件的 gmail 凭据登录到您的 google 帐户。然后浏览https://myaccount.google.com/security?hl=en#connectedapps 并启用“允许安全性较低的应用”
