是否可以使用 GMail 帐户从我的 Java 应用程序发送电子邮件？我已经使用 Java 应用程序配置了我的公司邮件服务器以发送电子邮件，但是当我分发应用程序时，这不会减少它。使用 Hotmail、Yahoo 或 GMail 中的任何一个的答案都是可以接受的。

首先下载JavaMail API并确保相关的 jar 文件在您的类路径中。

这是一个使用 GMail 的完整工作示例。

import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;

public class Main {

    private static String USER_NAME = "*****";  // GMail user name (just the part before "@gmail.com")
    private static String PASSWORD = "********"; // GMail password
    private static String RECIPIENT = "lizard.bill@myschool.edu";

    public static void main(String[] args) {
        String from = USER_NAME;
        String pass = PASSWORD;
        String[] to = { RECIPIENT }; // list of recipient email addresses
        String subject = "Java send mail example";
        String body = "Welcome to JavaMail!";

        sendFromGMail(from, pass, to, subject, body);
    }

    private static void sendFromGMail(String from, String pass, String[] to, String subject, String body) {
        Properties props = System.getProperties();
        String host = "smtp.gmail.com";
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", host);
        props.put("mail.smtp.user", from);
        props.put("mail.smtp.password", pass);
        props.put("mail.smtp.port", "587");
        props.put("mail.smtp.auth", "true");

        Session session = Session.getDefaultInstance(props);
        MimeMessage message = new MimeMessage(session);

        try {
            message.setFrom(new InternetAddress(from));
            InternetAddress[] toAddress = new InternetAddress[to.length];

            // To get the array of addresses
            for( int i = 0; i < to.length; i++ ) {
                toAddress[i] = new InternetAddress(to[i]);
            }

            for( int i = 0; i < toAddress.length; i++) {
                message.addRecipient(Message.RecipientType.TO, toAddress[i]);
            }

            message.setSubject(subject);
            message.setText(body);
            Transport transport = session.getTransport("smtp");
            transport.connect(host, from, pass);
            transport.sendMessage(message, message.getAllRecipients());
            transport.close();
        }
        catch (AddressException ae) {
            ae.printStackTrace();
        }
        catch (MessagingException me) {
            me.printStackTrace();
        }
    }
}

自然，您会想要在catch块中做更多的事情，而不是像我在上面的示例代码中那样打印堆栈跟踪。（删除这些catch块以查看来自 JavaMail API 的哪些方法调用会引发异常，以便您更好地了解如何正确处理它们。）

感谢@jodonnel和其他所有回答的人。我给他一个赏金，因为他的回答使我大约 95% 的方式得到了完整的答案。

像这样的东西（听起来你只需要改变你的 SMTP 服务器）：

String host = "smtp.gmail.com";
String from = "user name";
Properties props = System.getProperties();
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", "asdfgh");
props.put("mail.smtp.port", "587"); // 587 is the port number of yahoo mail
props.put("mail.smtp.auth", "true");

Session session = Session.getDefaultInstance(props, null);
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));

InternetAddress[] to_address = new InternetAddress[to.length];
int i = 0;
// To get the array of addresses
while (to[i] != null) {
    to_address[i] = new InternetAddress(to[i]);
    i++;
}
System.out.println(Message.RecipientType.TO);
i = 0;
while (to_address[i] != null) {

    message.addRecipient(Message.RecipientType.TO, to_address[i]);
    i++;
}
message.setSubject("sending in a group");
message.setText("Welcome to JavaMail");
// alternately, to send HTML mail:
// message.setContent("<p>Welcome to JavaMail</p>", "text/html");
Transport transport = session.getTransport("smtp");
transport.connect("smtp.mail.yahoo.co.in", "user name", "asdfgh");
transport.sendMessage(message, message.getAllRecipients());
transport.close();

其他人在上面有很好的答案，但我想在这里添加一个关于我的经验的注释。我发现，当使用 Gmail 作为我的 web 应用程序的出站 SMTP 服务器时，Gmail 只允许我发送大约 10 条左右的邮件，然后我必须手动执行反垃圾邮件响应以重新启用 SMTP 访问。我发送的电子邮件不是垃圾邮件，而是用户在我的系统上注册时的网站“欢迎”电子邮件。所以，YMMV，我不会依赖 Gmail 来开发生产网络应用程序。如果您代表用户发送电子邮件，例如安装的桌面应用程序（用户在其中输入自己的 Gmail 凭据），您可能会没事。

此外，如果您使用的是 Spring，这里有一个将 Gmail 用于出站 SMTP 的工作配置：

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="defaultEncoding" value="UTF-8"/>
    <property name="host" value="smtp.gmail.com"/>
    <property name="port" value="465"/>
    <property name="username" value="${mail.username}"/>
    <property name="password" value="${mail.password}"/>
    <property name="javaMailProperties">
        <value>
            mail.debug=true
            mail.smtp.auth=true
            mail.smtp.socketFactory.class=java.net.SocketFactory
            mail.smtp.socketFactory.fallback=false
        </value>
    </property>
</bean>

即使这个问题已经结束，我想发布一个计数器解决方案，但现在使用Simple Java Mail（开源 JavaMail smtp 包装器）：

final Email email = new Email();

String host = "smtp.gmail.com";
Integer port = 587;
String from = "username";
String pass = "password";
String[] to = {"to@gmail.com"};

email.setFromAddress("", from);
email.setSubject("sending in a group");
for( int i=0; i < to.length; i++ ) {
    email.addRecipient("", to[i], RecipientType.TO);
}
email.setText("Welcome to JavaMail");

new Mailer(host, port, from, pass).sendMail(email);
// you could also still use your mail session instead
new Mailer(session).sendMail(email);

                    }
                });

        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
        message.setSubject("Hello");
        message.setText("What's up?");

        Transport.send(message);

当您需要在同一 JVM 中的任何位置设置多个 SMTP 会话时，发布的代码解决方案可能会导致问题。

JavaMail FAQ 建议使用

Session.getInstance(properties);

代替

Session.getDefaultInstance(properties);

因为 getDefault 只会使用第一次调用时给定的属性。以后对默认实例的所有使用都将忽略属性更改。

请参阅http://www.oracle.com/technetwork/java/faq-135477.html#getdefaultinstance

一个简单的方法是为 POP3 访问配置/启用 gmail 帐户。这将允许您通过 gmail 服务器通过普通 SMTP 发送出去。

然后你只需通过 smtp.gmail.com 发送（在端口 587 上）

嗨试试这个代码....

package my.test.service;

import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Message;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class Sample {
    public static void main(String args[]) {
        final String SMTP_HOST = "smtp.gmail.com";
        final String SMTP_PORT = "587";
        final String GMAIL_USERNAME = "xxxxxxxxxx@gmail.com";
        final String GMAIL_PASSWORD = "xxxxxxxxxx";

        System.out.println("Process Started");

        Properties prop = System.getProperties();
        prop.setProperty("mail.smtp.starttls.enable", "true");
        prop.setProperty("mail.smtp.host", SMTP_HOST);
        prop.setProperty("mail.smtp.user", GMAIL_USERNAME);
        prop.setProperty("mail.smtp.password", GMAIL_PASSWORD);
        prop.setProperty("mail.smtp.port", SMTP_PORT);
        prop.setProperty("mail.smtp.auth", "true");
        System.out.println("Props : " + prop);

        Session session = Session.getInstance(prop, new Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(GMAIL_USERNAME,
                        GMAIL_PASSWORD);
            }
        });

        System.out.println("Got Session : " + session);

        MimeMessage message = new MimeMessage(session);
        try {
            System.out.println("before sending");
            message.setFrom(new InternetAddress(GMAIL_USERNAME));
            message.addRecipients(Message.RecipientType.TO,
                    InternetAddress.parse(GMAIL_USERNAME));
            message.setSubject("My First Email Attempt from Java");
            message.setText("Hi, This mail came from Java Application.");
            message.setRecipients(Message.RecipientType.TO,
                    InternetAddress.parse(GMAIL_USERNAME));
            Transport transport = session.getTransport("smtp");
            System.out.println("Got Transport" + transport);
            transport.connect(SMTP_HOST, GMAIL_USERNAME, GMAIL_PASSWORD);
            transport.sendMessage(message, message.getAllRecipients());
            System.out.println("message Object : " + message);
            System.out.println("Email Sent Successfully");
        } catch (AddressException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (MessagingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

这是一个易于使用的类，用于使用Gmail. 您需要将该JavaMail库添加到您的构建路径中，或者只使用Maven.

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.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

public class GmailSender
{
    private static String protocol = "smtp";

    private String username;
    private String password;

    private Session session;
    private Message message;
    private Multipart multipart;

    public GmailSender()
    {
        this.multipart = new MimeMultipart();
    }

    public void setSender(String username, String password)
    {
        this.username = username;
        this.password = password;

        this.session = getSession();
        this.message = new MimeMessage(session);
    }

    public void addRecipient(String recipient) throws AddressException, MessagingException
    {
        message.addRecipient(Message.RecipientType.TO, new InternetAddress(recipient));
    }

    public void setSubject(String subject) throws MessagingException
    {
        message.setSubject(subject);
    }

    public void setBody(String body) throws MessagingException
    {
        BodyPart messageBodyPart = new MimeBodyPart();
        messageBodyPart.setText(body);
        multipart.addBodyPart(messageBodyPart);

        message.setContent(multipart);
    }

    public void send() throws MessagingException
    {
        Transport transport = session.getTransport(protocol);
        transport.connect(username, password);
        transport.sendMessage(message, message.getAllRecipients());

        transport.close();
    }

    public void addAttachment(String filePath) throws MessagingException
    {
        BodyPart messageBodyPart = getFileBodyPart(filePath);
        multipart.addBodyPart(messageBodyPart);

        message.setContent(multipart);
    }

    private BodyPart getFileBodyPart(String filePath) throws MessagingException
    {
        BodyPart messageBodyPart = new MimeBodyPart();
        DataSource dataSource = new FileDataSource(filePath);
        messageBodyPart.setDataHandler(new DataHandler(dataSource));
        messageBodyPart.setFileName(filePath);

        return messageBodyPart;
    }

    private Session getSession()
    {
        Properties properties = getMailServerProperties();
        Session session = Session.getDefaultInstance(properties);

        return session;
    }

    private Properties getMailServerProperties()
    {
        Properties properties = System.getProperties();
        properties.put("mail.smtp.starttls.enable", "true");
        properties.put("mail.smtp.host", protocol + ".gmail.com");
        properties.put("mail.smtp.user", username);
        properties.put("mail.smtp.password", password);
        properties.put("mail.smtp.port", "587");
        properties.put("mail.smtp.auth", "true");

        return properties;
    }
}

示例用法：

GmailSender sender = new GmailSender();
sender.setSender("myEmailNameWithout@gmail.com", "mypassword");
sender.addRecipient("recipient@somehost.com");
sender.setSubject("The subject");
sender.setBody("The body");
sender.addAttachment("TestFile.txt");
sender.send();
