##java通过腾讯企业邮箱发送邮件(多人发送)

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";// 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.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 new passwordauthentication(account, password);
            }
        });
        // 使用ssl,企业邮箱必需 end
        // todo 显示debug信息 正式环境注释掉
        session.setdebug(true);
        return session;
    }
    // @param sender 发件人别名
    // @param subject 邮件主题
    //@param content 邮件内容
    //@param receiverlist 接收者列表,多个接收者之间用","隔开
    //@param filesrc 附件地址
    public void send(string sender, string subject, string content, string receiverlist, string filesrc) {
        try {
            session session = initproperties();
            mimemessage mimemessage = new mimemessage(session);
            mimemessage.setfrom(new internetaddress(account, sender));// 发件人,可以设置发件人的别名
            // 收件人,多人接收
            internetaddress[] internetaddressto = new internetaddress().parse(receiverlist);
            mimemessage.setrecipients(message.recipienttype.to, internetaddressto);
            // 主题
            mimemessage.setsubject(subject);
            // 时间
            mimemessage.setsentdate(new date());
            // 容器类 附件
            mimemultipart mimemultipart = new mimemultipart();
            // 可以包装文本,图片,附件
            mimebodypart bodypart = new mimebodypart();
            // 设置内容
            bodypart.setcontent(content, "text/html; charset=utf-8");
            mimemultipart.addbodypart(bodypart);
            // 添加图片&附件
            bodypart = new mimebodypart();
            bodypart.attachfile(filesrc);
            mimemultipart.addbodypart(bodypart);
            mimemessage.setcontent(mimemultipart);
            mimemessage.savechanges();
            transport.send(mimemessage);
        } catch (messagingexception e) {
            e.printstacktrace();
        } catch (unsupportedencodingexception e) {
            e.printstacktrace();
        } catch (ioexception e) {
            e.printstacktrace();
