如何用 java发送很多封邮件

Question

javamail 有自带的群发的功能。可是每次还是不能 一次把所有邮箱地址给它。我应该怎样做，才能把给所有的人一起发邮件呢？ 大家有没做过这个项目的，分享一下吧。

Answer 1

我今天学习Log4J的时候，配置下输出目的地MAIL，可以达到群发的功能。

Answer 2

不要用javamail吧。用spring自带的mail可以到达效果
/**
 * 发送邮件
 * @param 邮件内容
 * 
 * **/
public static void sendFileMail(String str) throws Exception {
JavaMailSenderImpl senderImpl = new JavaMailSenderImpl(); //[email protected];[email protected];[email protected];[email protected];[email protected]
String[] receivers = PropertyReader.getValue(Constant.COMMONFILEPATH, "mailreceivers").split(";");
receivers[0] = "[email protected]";
receivers[1] = "[email protected]";
receivers[2] = "[email protected]";
receivers[3] = "[email protected]";
receivers[4] = "[email protected]";
receivers[5] = "[email protected]";
//String[] receivers = PropertyReader.getValue(propertyFilePath, key);
//receivers[3] = "[email protected]";
senderImpl.setHost("smtp.xxx.cn");
senderImpl.setUsername("[email protected]");
senderImpl.setPassword("85571601");
MimeMessage mailMessage = senderImpl.createMimeMessage();
MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage, true, "utf-8"); messageHelper.setTo(receivers);
messageHelper.setFrom("[email protected]");
messageHelper.setSubject("流量包营销活动数据统计");
messageHelper.setText(str.toString(), true);
senderImpl.send(mailMessage);
//System.out.println("邮件发送成功！"); }这是我以前写的代码，楼主参考下吧。

是
[code=Java][
/**
     * 发送邮件
     * @param 邮件内容
     * 
     * **/
    public static void sendFileMail(String str) throws Exception {
            JavaMailSenderImpl senderImpl = new JavaMailSenderImpl();            //[email protected];[email protected];[email protected];[email protected];[email protected]
           /* String[] receivers = PropertyReader.getValue(Constant.COMMONFILEPATH,                     "mailreceivers").split(";");*/
            receivers[0] = "[email protected]";
            receivers[1] = "[email protected]";
            receivers[2] = "[email protected]";
            receivers[3] = "[email protected]";
            receivers[4] = "[email protected]";
            receivers[5] = "[email protected]";
            //String[] receivers = PropertyReader.getValue(propertyFilePath, key);
            //receivers[3] = "[email protected]";
            senderImpl.setHost("smtp.xxx.cn");
            senderImpl.setUsername("[email protected]");
            senderImpl.setPassword("85571601");
            MimeMessage mailMessage = senderImpl.createMimeMessage();
            MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage, true, "utf-8");            messageHelper.setTo(receivers);
            messageHelper.setFrom("[email protected]");
            messageHelper.setSubject("流量包营销活动数据统计");
            messageHelper.setText(str.toString(), true);
            senderImpl.send(mailMessage);
            //System.out.println("邮件发送成功！");        }/code]
