java向邮箱发送消息失败！

出现的错误如下：

代码：

public class Test {
public static void main(String[] args) {
Email email = new SimpleEmail();
email.setHostName("smtp.qq.com");// 发送服务器的名字
email.setAuthenticator(new DefaultAuthenticator("123456789@qq.com", "zzz"));//邮箱名和密码
email.setSSLCheckServerIdentity(true);
email.setSSLOnConnect(true);
email.setSmtpPort(465);
try {
email.setFrom("123456789@qq.com");
email.setSubject("测试");// 发送主题
email.setMsg("邮件测试内容！");// 发送内容
email.addTo("123456789@qq.com");// 接受邮件账户
email.send();// 发送
} catch (EmailException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}// 发送邮箱
}
}

使用的jar包如下：

使用如上代码，首先确保邮箱已经开启了 POP3、SMTP等服务。

开启之后，一定要生成授权码，上面的邮箱名和密码

email.setAuthenticator(new DefaultAuthenticator("123456789@qq.com", "zzz"));//邮箱名和密码

密码是授权码，而不是你的邮箱真正的密码。
