    <artifactId>mail</artifactId>
    <version>1.4.7</version>
    </dependency>

代码实现

    import javax.mail.Authenticator;
    import javax.mail.MessagingException;
    import javax.mail.PasswordAuthentication;
    import javax.mail.Session;

    import javax.mail.internet.MimeMessage.RecipientType;
    
    public class Yte {
    	  public static void main(String[] args) throws AddressException,MessagingException {       
    		   
    	        // 创建Properties 类用于记录邮箱的一些属性
    	        Properties props = new Properties();
    	        // 表示SMTP发送邮件，必须进行身份验证
    	        props.put("mail.smtp.auth", "true");
    	        //此处填写SMTP服务器
    	        props.put("mail.smtp.host", "smtp.qq.com");
    	        //端口号，QQ邮箱端口587
    	        props.put("mail.smtp.port", "587");
    	        // 此处填写，写信人的账号
    	        props.put("mail.user", "xxxxxxxxxx@qq.com");
    	        // 此处填写16位STMP口令
    	        props.put("mail.password", "xxxxxxxx");
    
    	        // 构建授权信息，用于进行SMTP进行身份验证
    	        Authenticator authenticator = new Authenticator() {
    
    	            protected PasswordAuthentication getPasswordAuthentication() {
    	                // 用户名、密码
    	                String userName = props.getProperty("mail.user");
    	                String password = props.getProperty("mail.password");
    	                return new PasswordAuthentication(userName, password);
    	            }
    	        };
    	        // 使用环境属性和授权信息，创建邮件会话
    	        Session mailSession = Session.getInstance(props, authenticator);
    	        // 创建邮件消息
    	        MimeMessage message = new MimeMessage(mailSession);
    	        // 设置发件人
    	        InternetAddress form = new InternetAddress(props.getProperty("mail.user"));
    	        message.setFrom(form);
    
    	        // 设置收件人的邮箱
    	        InternetAddress to = new InternetAddress("xxxxxxxxxx@qq.com");
    	        message.setRecipient(RecipientType.TO, to);
    
    	        // 设置邮件标题
    	        message.setSubject("标题");
    
    	        // 设置邮件的内容体
    	        message.setContent("内容", "text/html;charset=UTF-8");
    
    	        // 最后当然就是发送邮件啦
    	        Transport.send(message);
    		   
    		   
    	   }
    }
