【java】利用javamail发送邮件

如何通过javamail来发送邮件(SSL加密)？？这里做一个小测试

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;

public class JavaSendEmail {
    public static void main(String[] args) throws MessagingException {
        Properties properties = new Properties();
        properties.put("mail.transport.protocol","smtp");//协议
        properties.put("mail.smtp.host","IP地址");
        properties.put("mail.smtp.port",465);//端口号
        properties.put("mail.smtp.auth","true");
        properties.put("mail.smtp.ssl.enable","true");//设置ssl安全连接
        properties.put("mail.debug","true");//显示debug信息

        //会话对象
        Session session = Session.getInstance(properties);
        //获取邮件对象
        Message message = new MimeMessage(session);
        //设置发件人邮箱地址
        message.setFrom(new InternetAddress("[email protected]"));
        //设置收件人邮箱地址
        message.setRecipients(Message.RecipientType.TO,
                new InternetAddress[]{
                        new InternetAddress("收件人的邮箱@"),
                });
        //设置邮件标题
        message.setSubject("发给我自己");
        //设置邮件内容
        message.setText("testtesttesttesttest");
        //得到邮箱对象
        Transport transport = session.getTransport();
        transport.connect("账号@","密码");
        //发送邮件
        transport.sendMessage(message,message.getAllRecipients());
        //关闭邮件对象
        transport.close();
    }
}
