这里我们以QQ邮箱为例。
一、导入依赖:
<dependencies> <!-- https://mvnrepository.com/artifact/javax.activation/activation --> <dependency> <groupId>javax.activation</groupId> <artifactId>activation</artifactId> <version>1.1.1</version> </dependency> <!-- https://mvnrepository.com/artifact/javax.mail/mail --> <dependency> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> <version>1.4.7</version> </dependency> </dependencies>
二、设置自己的QQ邮箱
开启以上两项服务。
三、具体实现
import com.sun.mail.util.MailSSLSocketFactory; import javax.mail.*; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; import java.util.Properties; public class SendEmail { /* addressee:收件人邮箱 *title:邮件标题标题 *content:邮件内容 */ public static void send(String addressee, String title, String content) throws Exception { Properties prop = new Properties(); prop.setProperty(\"mail.host\", \"smtp.qq.com\");//邮件服务器:QQ prop.setProperty(\"mail.transport.protocol\", \"smtp\");//邮件发送协议:smtp prop.setProperty(\"mail.smtp.auth\", \"true\");//需要验证用户名和密码 //QQ邮箱,还需要设置SSL加密 MailSSLSocketFactory factory = new MailSSLSocketFactory(); factory.setTrustAllHosts(true); prop.put(\"maim.smtp.ssl.enable\", \"true\"); prop.put(\"maim.smtp.ssl.socketFactory\", factory); //javaMail发送email的五个步骤 //1.定义一个整个应用环境需要的session对象 Session session = Session.getDefaultInstance(prop, new Authenticator() { @Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(\"自己的邮箱\", \"授权码\"); } }); //开启session的debug模式 session.setDebug(true); //2.通过session得到transport对象 Transport transport = session.getTransport(); //3.使用邮箱用户名和授权码连接上服务器 transport.connect(\"smtp.qq.com\", \"自己的邮箱\", 授权码\"); //4.创建邮件 //创建邮件对象 MimeMessage message = new MimeMessage(session); //发邮件人 message.setFrom(new InternetAddress(\"自己的邮箱\")); //收件人 可以群发setRecipients message.setRecipient(Message.RecipientType.TO, new InternetAddress(addressee)); //邮件标题 message.setSubject(title); //邮件内容,前内容,后格式 message.setContent(content, \"text/html;charset=UTF-8\"); //5.发送邮件 transport.sendMessage(message, message.getAllRecipients()); //6.关闭连接 transport.close(); } }
