## Java通过腾讯企业邮箱发送邮件 ##

1.  企业邮箱需要使用ssl
    
        private static String account = "企业邮箱账户";// 登录账户
        private static String password = "企业邮箱密码";// 登录密码
        private static String host = "smtp.exmail.qq.com";// 服务器地址
        private static String port = "465";// 端口
        private static String protocol = "smtp";// 协议
        //初始化参数
        public static Session initProperties() {
            Properties properties = new Properties();
            properties.setProperty("mail.transport.protocol", protocol);
            properties.setProperty("mail.smtp.host", host);
            properties.setProperty("mail.smtp.port", port);
            // 使用smtp身份验证
            properties.put("mail.smtp.auth", "true");
            // 使用SSL,企业邮箱必需 start
            // 开启安全协议
            MailSSLSocketFactory mailSSLSocketFactory = null;
            try {
                mailSSLSocketFactory = new MailSSLSocketFactory();
                mailSSLSocketFactory.setTrustAllHosts(true);
            } catch (GeneralSecurityException e) {
                e.printStackTrace();
            }
            properties.put("mail.smtp.enable", "true");
            properties.put("mail.smtp.ssl.socketFactory", mailSSLSocketFactory);
            properties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
            properties.put("mail.smtp.socketFactory.fallback", "false");
            properties.put("mail.smtp.socketFactory.port", port);
            Session session = Session.getDefaultInstance(properties, new Authenticator() {
                @Override
                protected PasswordAuthentication getPasswordAuthentication() {

            return session;
        }
